There were also tears, as there often is when the stakes are high, as Molly Huddle celebrated too soon and lost out on 10,000m bronze.
Thanks, as always, for joining us. There will be more of the same on Tuesday, with five gold medals to be won. Can Greg Rutherford add the world title to his Olympic, European and Commonwealth golds? We'll find out on Tuesday afternoon.
If you missed any of today's action, or just want to watch it all again, there will be highlights online and on BBC Two from 19:00 BST.
Post update
There's no more track and field for us to watch which means we will call it a day. Sprinting gold for Jamaica as another of the country's great wins 100m gold, there was a shock in the pole vault as Renaud Lavillenie once again fails to win a world title, while Olympic champion Greg Rutherford has progressed to the long jump final.
'Coe will do great things'
'Huddle may never have that opportunity again'
Women's 10,000m final
Michael Johnson
BBC Sport athletics expert & 400m world record holder
Talking about American Molly Huddle who was set to win a bronze medal in the women's 10,000m, but celebrated too early and was pipped on the line by compatriot Emily Infeld.
"Molly Huddle had a medal and gave it up with a real freshman mistake. It's unfortunate for her. She is disappointed and embarrassed and may never have that opportunity ever again. That medal was hers."
Picture of the day
As we prepare to wrap up for the day, it'd be remiss not to mention Rolanda Bell who made a splash in the women's 3000m steeplechase heats today, falling head over heels into the water, a moment which was captured beautifully by a photographer.

'Schippers has a very bright future in the 100m'
Women's 100m final
Michael Johnson
BBC Sport athletics expert & 400m world record holder
"Those were the best sprinters in the world so for a European to get a silver medal when everyone is there then that bodes well for Dafne Schippers.
"I wouldn't expect her to go back to the heptathlon and she has a very bright future in the 100m. It was a tough field and she was able to come out with a silver medal and a personal best."

The medal table has changed since this morning, with Kenya and Jamaica overtaking Britain at the top. Britain still in third, though, after day three.
Fraser-Pryce's hair secrets revealed
Phil Jones asks Shelly-Ann Fraser-Pryce about her haircut and she reveals she coloured her hair herself. "I had these green braids and I thought, what the heck," she says, laughing, and looking like she's just stepped out of a salon.

'Impressive running'
Close but not close enough

If it were the 110m perhaps Dafne Schippers would have caught Shelly-Ann Fraser-Pryce but, on the other hand, if the finishing line wasn't looming the world champion probably would not have slowed down and celebrated.

Selfies for Fraser-Pryce
Shelly-Ann Fraser-Pryce is waving to her fans,and there are many of them, and poses with the Jamaican flag for the photographers. The hair and the Jamaican flag go together nicely, which I suppose is the point.
There are also a few obligatory selfies to take, of course.

Bronze for Bowie
America's Tori Bowie, another who has swapped events, from long jump to sprinting, wins 100m bronze in 10.86.
'What a start!'
Darren Campbell
Former British sprinter on BBC Radio 5 live
"Fraser-Pryce did not leave anything to chance. I've never seen anyone come out of the blocks so explosively in my life - male or female - and she opened a four metre gap.
"Schippers did not fear her and never gave up but she couldn't quite close the gap."

A golden hat-trick for Fraser-Pryce

Shelly-Ann Fraser-Pryce had time to salute as she crossed the line, celebrating before the finish which allowed Dafne Schippers to close in on her. It was a straightforward victory in the end for the Jamaican.

Schippers, a heptathlete by trade before she switched to sprinting, takes silver in a national record 10.81.

'A great athlete and character'
Men's 3,000m steeplechase final
Brendan Foster
Olympic medallist and BBC athletics commentator
"That was absolutely amazing from Ezekiel Kemboi. You don't win four world titles and two Olympic Games without being the very best. He is a great athlete and a character of the track."
Kemboi wins 3,000m steeplechase
Blimey. An incredible turbo-charged burst of speed from Ezekiel Kemboi after the bell and the Kenyan overtakes everyone and maintains his pace to capture a fourth consecutive world title. An astonishing sprint finish, clocking 8:11.28 to win.
Predictably, it was a Kenyan top three, with Conseslus Kipruto (8:12.38) second and Brimin Kiprop Kipruto (8:12.54) joining them on the podium.

American Evan Jager, who looks more like a decathlete such is his stature, is ranked second in the world this year and bursts into the lead at the bell... but he's quickly overtaken and his chances are gone, gone, gone...

"It's going to be a sprinter's race," says Brandan Foster of the men's 3,000m steeplechase final. 2013 World silver medallist Conseslus Kipruto is leading the bunch. Blond American Evan Jager is by his side.

'An honour and a pleasure'
'The French faces tell the story'
Men's pole vault final
Steve Backley
Four-time European javelin champion on BBC TV
"A big shock. The faces of the French team tell the story. When he gets it right, he is utterly brilliant, but not today.
"Renaud Lavillenie is out and may not even medal. Amazing."
No gold for Lavillenie
Olympic champion, world record holder, the overwhelming favourite, Renaud Lavillenie has one more chance to rescue himself from a dire situation.
5.90m is the height, if he fails then he will not become world champion, the title which has evaded him throughout his career.
He goes through the usual routine, but it's not the outcome he's used to. The bar wobbles and falls once again and the Frenchman can only shake his head in disbelief.
Winner - Ibarguen wins triple jump gold
A season's best 14.90m from Caterine Ibarguen is good enough for triple jump gold, which means the Colombian retains her world crown.
Silver will be awarded to Hanna Knyazyeva-Minenko (14.78m) while Kazakhstan's Olga Rypakova will take home a bronze.

Canada's Barber clears 5.90m in pole vault
Canada's Shawnacy Barber succeeds where Olympic champion Renaud Lavillenie failed - clearing 5.90m on his first attempt and that has turned the screw ever so slightly on the Frenchman, who is pacing up and down in the background.

Eventually he sets off, a puff of the cheeks, upwards he goes... his thigh grazes the bar and gravity does its job. The Olympic champion must go again at that height.

"If you're trying to decide whether English Gardner is your favourite name in the women's 100m, it might be worth knowing that her US team-mate Tori Bowie's full first name is Frentorish."
"I think Tori Bowie can challenge Fraser-Pryce in the final. Her technique is very smooth and if she can execute her start and drive phase she will come back on Fraser-Pryce and, if she is in the lead, I'm not sure Fraser-Pryce can catch her."
Bowie wins in 10.87
Tori Bowie the favourite to progress, and that isn't because she's got an A-lister's name. The American reacts fabulously, stumbles slightly coming out of the blocks, though, and doesn't relinquish the lead for the entirety of the race, clocking 10.87 to win.

Describing the challenges he faced coaching Ennis-Hill after she gave birth 13 months ago, Minichiello added: "The running was superb from day one, the difficulty was doing stuff like jumping and bouncing.
"That was very difficult when we started and we had some Achilles issues to deal with as well. You learn as you are going along and do the best you can to make a compromise."

Jessica Ennis-Hill's coach Toni Minichiello is currently chatting to Gabby Logan on the telly, but earlier he was speaking to the good folk on BBC Radio 5 live.
"When she first came back to the sport it was very difficult with the power events and then we had injury issues, so it was slow progress, but when she got to the London Anniversary Games, it was there that we felt she should go," says Minichiello.

Is Meghan Beesley through to the 400m hurdles final as a fastest loser? Unfortunately not, her time of 55.41 not quite good enough, but Eilidh Child is through as a fastest loser.
America's Shamier Little is also through as a fastest loser, and hopefully she will wear that eye-catching bow in her hair in the final.
Beesley third, Hejnova wins
Ouch. Smash, bang, wallop. America's Kori Carter runs into a barrier and she's gone, gone gone.
Meghan Beesley finishes third, with the world champ Zuzana Hejnova strolling over the line in first with Jamaica's Janieve Russell second.
Beesley gunning for the final
British eyes on Meghan Beesley in lane four as she prepares to run and hurdle in the final semi-final. The Briton ran a personal best 54.42 to qualify from the heats, but is up against world champion Zuzana Hejnova in this ding-dong.

Quote Message: I tried to go off hard, but lost my stride on the bend and lost momentum into nine and 10. I'm so upset.

I tried to go off hard, but lost my stride on the bend and lost momentum into nine and 10. I'm so upset. I don't think it will be enough to make the final with the way these girls are running. I'll be very lucky if I make the final.
Child is downbeat, but there's still hope as she is currently the quickest loser with one more semi-final to come...
Petersen beats Spencer
The great Kaliese Spencer controlling the race early on, but is passed by Denmark's Sara Slott Petersen (54.34) with 20m or so to go. What happened to Shamier Little? The American and her bow crossed the line in third in 54.86, an iffy hurdle coming out of the bend costly.
It was a fairly slow race, which is good news for Eilidh Child, says Steve Cram in the commentary box.
Women's 400m hurdles semis
The second women's 400m hurdles semi-final is upon us and although there is no Briton racing that does not mean we're not interested, mainly because we want to see if Shamier Little's radioactive green bow stays on top of her head for the entire lap.
It's an incredible accessory to wear during the heat of battle, but why not add extra glamour to such occasions?
'Back to the drawing board'
Women's 400m hurdles semi-finals
Colin Jackson
Two-time world 110m hurdles champion
"Eilidh Child will be disappointed with that performance. She would have been looking at this list and thought she could make it through.
"But the problem was with hurdles six and seven and she took hurdle eight on her wrong leg. It was just off sync for her and it is back to the drawing board. But she could still get through as a fastest loser."
Child third in first semi-final
BBCCopyright: BBC
As the bookies' would have predicted, Eilidh Child, Cassandra Tate and Wenda Nel coming round the final bend together. Child slightly ahead... but she's overtaken by eventual winner Tate (54.33 seconds) and Nel, the Briton stuttering on the final couple of hurdles.
Child (54.80 seconds) must now wait to find out if she is one of the two fastest losers.
Women's 400m hurdles
The first two in each semi-final will qualify, plus the two fastest losers. Should European champ Eilidh Child qualify, it would be her second successive final at the World Championships.
On paper, the Scot is the third quickest this year of the line-up, behind America's Cassandra Tate and South Africa's Wenda Nel.
Coming up

For those of you who like graphics and a bit of detail on your schedule then this one's for you. Briton Eilidh Child (lane 5) is in the first 400m hurdles semi-final. The Scot sipping juice as she waits to be called into position.
Day three schedule
I guess we should focus on the day ahead. Five gold medals to be won, the fastest women on the planet on show - this is how it will all unfold:
12:00 men's javelin throw (qualification, Group A)
12:05 men's pole vault final
12:10 women's 400m hurdles semi-finals
12:30 women's triple jump final

'Hopefully I can compete with these guys'
More quotes from British sprinter Adam Gemili who feels he has learned a lot by watching the best sprinters in the 100m final.
He tells BBC Sport: "I'm always learning and improving. Hopefully as I get older I can go out and compete with these guys. I just have to train hard. If I was out on the start line hopefully I would've got into the final but it was not to be."
'A wicked experience out here'
British sprinter Adam Gemili, who is out in China, but will not compete in the 4x100m relay because of injury, has been talking to BBC Sport.
He says: "My injury is better now, it's more a precaution to not run. We've got a few big years coming up but if I went out and did something silly then that would put me further back.
"Watching last night's 100m was so cool. It has been a wicked experience out here. With Bolt you always have to believe in this guy and never write him off. Gatlin just fell apart but what a race to witness."

Usain Bolt places his video recorder (are they still called camcorers?!) on the podium step as he is presented with a red bouquet and his ninth world championship gold medal. Where would the sport be without him? What will the sport do when he's gone?
'Atmosphere like no other'
Darren Campbell
Former British sprinter on BBC Radio 5 live
"It was an atmosphere like no other in the 100m final and, apart from Usain Bolt, all the experienced athletes crumbled under the pressure. It was telling that the two most inexperienced athletes took bronze ahead of Gay, Powell and others."
'Bolt the greatest'
Mike Costello
BBC Radio 5 live athletics commentator
"Usain Bolt, the greatest athlete of all time, the man who secured such a significant victory for his sport, stands alone above all others with nine gold medals at World Championships."

Track and field's principal showman, Usain Bolt, is back on the track where winning has become routine, preparing for the 100m medal ceremony and the Jamaican has a video camera in his hand, filming the moment.
The 28-year-old jumped 8.25m, with American Jeff Henderson, the leading long jumper this year, recording 8.36m.
Rutherford has gone on Twitter, well, asked his girlfriend to do so, and posted this message.
'Ohuruogu a solid performer'
Women's 400m heats
Michael Johnson
BBC Sport athletics expert & 400m world record holder
"Christine Ohuruogu is a solid performer and has relied on that throughout her career. She is not one of the fastest runners this year but will use this race to get into shape.
"She ran a very even-paced race. She has got really good technique, is a very powerful runner and has great upper-body strength. If there is any athlete that I don't worry about, it is Christine. She will always be right there."
Olympic long jump champion Greg Rutherford reached Tuesday's final, finishing second in qualifying.
Defending champion Christine Ohuruogu moved on to the 400m semi-finals by winning her heat, with fellow Briton Anyika Onuora also going through in a personal best time of 51.14secs.
And Holly Bradshaw recorded a season's best of 4.55m to finish joint top of qualifying in the pole vault.

'Monday morning motivation'
Talking of heptathletes, Katarina Johnson-Thompson had a horrible day yesterday, as she broke down in tears after her hopes of a heptathlon medal at the World Championships in Beijing ended in disappointment.
The Briton finished 28th, her chances effectively ending when she failed to record a score in the long jump.
But today she has posted this message on Twitter.

The food of champions
What does an athlete do after winning a world title? Treat herself to four puddings, it seems. "Yum," Jessica Ennis-Hill simply said in her caption on Instagram.

"She has had to build up her training and do everything right, but she has peaked at the right time. She said she would be happy with a bronze medal but what an amazing job she did.
"She is so happy being a mum and her son is going to be so proud of her."
Super mum, super athlete
Sometimes no words are necessary. The Guardian sum up Jessica Ennis-Hill's feats in one glorious image.
Sean Ingle writes: "Only a handful of women have celebrated a world title after giving birth, and the majority of those have come in endurance races, where pregnancy may confer some benefits. But in the heptathlon? Never."

We've not talked much about Jessica Ennis-Hill yet. Let's address that.
Thirteen months after giving birth to her son Reggie, Ennis-Hill is now a world champion. A remarkable achievement.
The 29-year-old started her comeback on a stationary bike in November, was then troubled by an Achilles injury. There were doubts whether she would compete in Beijing, but GO to the Chinese capital she did and my how she triumphed.

It's that man again, the one who saved athletics. "Usain Bolt gave the gift of life to athletics as he produced surely his greatest win to raise the sport from its death bed," writes Alex Spink in the Daily Mirror.

What the papers say
I think it's universally agreed among headline writers that Usain Bolt is the saviour of athletics.
"Usain Bolt rode to the rescue of his beleaguered sport once again as he dashed Justin Gatlin's hopes of 100 metres gold at the World Championships in Beijing," says Guy Aspin in the Independent.

'Impossible to ban for life'
Michael Johnson
BBC Sport athletics expert & 400m world record holder
"Usain Bolt does feel responsible and people were depending on him. People appreciate him and what he brings to the sport. He is an entertainer but he takes the sport very seriously.
"It is impossible to ban people for life. That is what the fans want, but legally it is not possible so we will have to accept that drug cheats will come back into the sport. For the fans of this sport, the sentiment was they would have preferred it if Justin Gatlin had gone out in the first round."

Mind games and fistbumps
Tom Fordyce
Chief sports writer in Beijing
"On the morning after the night before, all the talk in Beijing - or at least in the sporting bubble around the Bird's Nest - has been of a 100m final that still has all who saw it shaking their heads in wonder.
"Why did Gatlin fall apart? Where did Bolt find the self-belief? How critical were the mind games that the Jamaican tried on his rival as they warmed up?
"There is even a theory it came down to a fistbump, offered by Bolt to his rival seconds before gun. Linford Christie once growled like an angry bear at Carl Lewis when he tried the same thing before a World final. Gatlin, nonplussed, accepted it - and in that moment, goes the theory, subconsciously ceded control and authority to the great champion."
Did Bolt save athletics?

It was important but I don't think he saved athletics, it was just a battle of two sprinters and technically who's better. Everyone was a bit biased towards Usain Bolt and the majority of us are glad he delivered.
0.01 seconds between good and bad?
The 100m final was close, there was hardly anything in it, just a hundredth of a second separating Usain Bolt and his rival Justin Gatlin but that was enough for gold in what has been described as the six-time Olympic champion's greatest performance of all.
Gatlin was the favourite, he'd run the four quickest times of the year, but that accounted for nothing in Beijing. They don't give gold medals based on Diamond League performances, and the majority of the world is happy about that.
"0.01 secs between good and evil as Bolt pips drugs cheat," headlined the Daily Mail today.

Unsurprisingly, Usain Bolt and Jessica Ennis-Hill dominate the back pages of this morning's national papers. "The day athletics smiled again," headlines the Daily Telegraph.

"Once again, Bolt proved us all fools," he writes. "On a night that could have ended with the sport no longer teetering on the abyss but plummeting over it, the victories of Bolt and, a few hours earlier, Jessica Ennis-Hill in the heptathlon, gave the believers something to cling to and the doubters reason to perhaps think again."

Post update
Hello! Welcome to live coverage of the third day of the World Championships in Beijing, but we can't talk about today until we reflect on a wonderful yesterday.
Jessica Ennis-Hill produced the mother of sporting comebacks by winning heptathlon gold while Usain Bolt pulled off what seemed impossible, beating Justin Gatlin, a two-time drug cheat and the dominant force of sprinting in the last two years. Incredible performances from incredible athletes.
Post update
The sun rose again this morning, as it always does, and the clocks continue to tick. Everything seems the same, but something's a little different. Worriers are smiling, skeptics are filled with hope. The smiling assassins of cynicism triumphed in Beijing yesterday and dark clouds are gradually disappearing.

There were also tears, as there often is when the stakes are high, as Molly Huddle celebrated too soon and lost out on 10,000m bronze.
Thanks, as always, for joining us. There will be more of the same on Tuesday, with five gold medals to be won. Can Greg Rutherford add the world title to his Olympic, European and Commonwealth golds? We'll find out on Tuesday afternoon.

There's no more track and field for us to watch which means we will call it a day. Sprinting gold for Jamaica as another of the country's great wins 100m gold, there was a shock in the pole vault as Renaud Lavillenie once again fails to win a world title, while Olympic champion Greg Rutherford has progressed to the long jump final.
'Coe will do great things'
'Huddle may never have that opportunity again'
Women's 10,000m final
Michael Johnson
BBC Sport athletics expert & 400m world record holder
Talking about American Molly Huddle who was set to win a bronze medal in the women's 10,000m, but celebrated too early and was pipped on the line by compatriot Emily Infeld.
"Molly Huddle had a medal and gave it up with a real freshman mistake. It's unfortunate for her. She is disappointed and embarrassed and may never have that opportunity ever again. That medal was hers."
Picture of the day
As we prepare to wrap up for the day, it'd be remiss not to mention Rolanda Bell who made a splash in the women's 3000m steeplechase heats today, falling head over heels into the water, a moment which was captured beautifully by a photographer.
'Schippers has a very bright future in the 100m'
Women's 100m final
Michael Johnson
BBC Sport athletics expert & 400m world record holder
"Those were the best sprinters in the world so for a European to get a silver medal when everyone is there then that bodes well for Dafne Schippers.
"I wouldn't expect her to go back to the heptathlon and she has a very bright future in the 100m. It was a tough field and she was able to come out with a silver medal and a personal best."
'I'm tired of 10.7s'
Women's 100m final
Shelly-Ann Fraser-Pryce has just won a gold medal, but is not too impressed with her time.
Medal table
The medal table has changed since this morning, with Kenya and Jamaica overtaking Britain at the top. Britain still in third, though, after day three.
Fraser-Pryce's hair secrets revealed
Phil Jones asks Shelly-Ann Fraser-Pryce about her haircut and she reveals she coloured her hair herself. "I had these green braids and I thought, what the heck," she says, laughing, and looking like she's just stepped out of a salon.
'Impressive running'
Close but not close enough
If it were the 110m perhaps Dafne Schippers would have caught Shelly-Ann Fraser-Pryce but, on the other hand, if the finishing line wasn't looming the world champion probably would not have slowed down and celebrated.
'Wow! I'm so happy'
Women's 100m final
Selfies for Fraser-Pryce
Shelly-Ann Fraser-Pryce is waving to her fans,and there are many of them, and poses with the Jamaican flag for the photographers. The hair and the Jamaican flag go together nicely, which I suppose is the point.
There are also a few obligatory selfies to take, of course.

"Fraser-Pryce did not leave anything to chance. I've never seen anyone come out of the blocks so explosively in my life - male or female - and she opened a four metre gap.
"Schippers did not fear her and never gave up but she couldn't quite close the gap."

Colin Jackson
Two-time world 110m hurdles champion
"Shelly-Ann Fraser-Pryce will be very pleased with the victory but I'm not sure she will be happy with the way she ran.
"The start was not as good as I expected and that's why we didn't see her get close to her personal best of 10.70."
A golden hat-trick for Fraser-Pryce
Shelly-Ann Fraser-Pryce had time to salute as she crossed the line, celebrating before the finish which allowed Dafne Schippers to close in on her. It was a straightforward victory in the end for the Jamaican.
Fraser-Pryce wins 100m title in 10.76
Shelley-Ann Fraser-Pryce the favourite, the defending champion, out of the blocks first, ahead of everyone by halfway but Dafne Schippers is closing her down...
...the finishing line comes to Fraser-Pryce's rescue before the Dutchwoman can close in, and she crosses the line in 10.76 to successfully defend her title.
Schippers, a heptathlete by trade before she switched to sprinting, takes silver in a national record 10.81.

Here are the contenders, featuring the big names... defending champion Shelly-Ann Fraser-Pryce, European champion Dafne Schippers, America's Tori Bowie... and I could go on.
Women's 100m final
If the women's 100m finalists can finish with the elan of Ezekiel Kemboi we will have experienced a wonderful race.
The fastest women in the world, who also happen to have the best haristyles in the world will burst out of the blocks at around 14:35 BST, which is pretty soon really.
Vote result
Earlier we asked if you think Usain Bolt and Mo Farah will do the double and the majority of you think both will - 69% of you in fact.
Thanks for voting.
'A great athlete and character'
Men's 3,000m steeplechase final
Brendan Foster
Olympic medallist and BBC athletics commentator
"That was absolutely amazing from Ezekiel Kemboi. You don't win four world titles and two Olympic Games without being the very best. He is a great athlete and a character of the track."
Kemboi wins 3,000m steeplechase
Blimey. An incredible turbo-charged burst of speed from Ezekiel Kemboi after the bell and the Kenyan overtakes everyone and maintains his pace to capture a fourth consecutive world title. An astonishing sprint finish, clocking 8:11.28 to win.
Predictably, it was a Kenyan top three, with Conseslus Kipruto (8:12.38) second and Brimin Kiprop Kipruto (8:12.54) joining them on the podium.
3,000m steeplechase final
American Evan Jager, who looks more like a decathlete such is his stature, is ranked second in the world this year and bursts into the lead at the bell... but he's quickly overtaken and his chances are gone, gone, gone...
Kenyans dominating steeplechase
"It's going to be a sprinter's race," says Brandan Foster of the men's 3,000m steeplechase final. 2013 World silver medallist Conseslus Kipruto is leading the bunch. Blond American Evan Jager is by his side.
Pole vault gold for Barber
Both Shawnacy Barber and Raphael Holzdeppe fail to clear 6.00m after three attempts which means gold will be awarded to young Canadian Barner, who cleared 5.90m with his first attempt.

The final now a showdown between the German and Canada's Shawnacy Barber. Renaud Lavillenie has been confirmed as the bronze medallist, which is not what he came to Beijing for.
'An honour and a pleasure'
'The French faces tell the story'
Men's pole vault final
Steve Backley
Four-time European javelin champion on BBC TV
"A big shock. The faces of the French team tell the story. When he gets it right, he is utterly brilliant, but not today.
"Renaud Lavillenie is out and may not even medal. Amazing."
No gold for Lavillenie
Olympic champion, world record holder, the overwhelming favourite, Renaud Lavillenie has one more chance to rescue himself from a dire situation.
5.90m is the height, if he fails then he will not become world champion, the title which has evaded him throughout his career.
He goes through the usual routine, but it's not the outcome he's used to. The bar wobbles and falls once again and the Frenchman can only shake his head in disbelief.
Winner - Ibarguen wins triple jump gold
A season's best 14.90m from Caterine Ibarguen is good enough for triple jump gold, which means the Colombian retains her world crown.
Silver will be awarded to Hanna Knyazyeva-Minenko (14.78m) while Kazakhstan's Olga Rypakova will take home a bronze.
Women's 10,000m final
Her fellow finalists aren't running quick enough so Kenya's Sally Jepkosgei Kipyego steps forward, increases the tempo and gets ready for a battle royal. Ten laps remaining and we're set for an intriguing finale.
Lavillenie fails at 5.90m
Kate Avery currently 18th in the women's 10,000m, but over in the pole vault Renaud Lavillenie is attempting 5.90m, his second effort...
Does he do it? No, no, no. His knee touches the pole and the Olympic champion has one more opportunity to keep his golden hopes alive. Oof the tension.
Canada's Barber clears 5.90m in pole vault
Canada's Shawnacy Barber succeeds where Olympic champion Renaud Lavillenie failed - clearing 5.90m on his first attempt and that has turned the screw ever so slightly on the Frenchman, who is pacing up and down in the background.
Women's 10,000m final
Japan's Rei Ohara leading the women around the track in the 10,000m. Everyone's huddled together, no-one yet to make a move.
First failure for Lavillenie at 5.90m
Renaud Lavillenie encourages the spectators to slowly clap before asking them to dim the noise. Make your mind up, Renaud.
The bar is set at 5.90m, the Frenchman being made to wait for some reason or another...
Eventually he sets off, a puff of the cheeks, upwards he goes... his thigh grazes the bar and gravity does its job. The Olympic champion must go again at that height.
Women's 10,000m final
The distance runners are making their way around, and around, and around the track. The race features former double world champion Vivian Cheruiyot, another mum who is making her comeback on the track.
She missed the World Championships in Moscow in 2013 to give birth to her son, but has returned in a bid to win what would be her fourth world title.
Coming up
Haven't had your fix of graphics and timetables? In a bid to sate you, here's what's still to come in the Bird's Nest.
Ibarguen leads triple jump final
The women's 10,000m final, which features Britain's Kate Avery, is about to begin but let's turn our attention on to the women's triple jump final.
Colombia's Caterinel Ibarguen has set the standard, leading the way with a 14.90m hop, skip and a jump. It's hardly a surprise as the defending champion is unbeaten in 28 competitions.

Yousif into the final
According to the list in front of me, Rabah Yousif is the fastest loser which means there's a place for the Briton in Wednesday's final. A doff of the cap to you, Mr Yousif.
'Rooney was struggling'
Men's 400m semi-finals
Michael Johnson
BBC Sport athletics expert & 400m world record holder
"Martyn Rooney was on the right-hand side of his lane and he was struggling - the arms were not going in the right direction.
"I believe the first round, where he had a personal best, took it out of him and that's unfortunate for him."
Van Niekerk wins, Rooney sixth
Men's 400m semi-finals
Martyn Rooney is in lane seven and he's feeling the breath of Wayde Van Niekerk (44.31) on his shoulder as they burst into the final corner. It's the South African who wins, with LaShawn Merrit closely behind in second with a season's best 44.34.
Britain's Rooney heavy-legged, finishing in sixth in 45.29.
Post update
Men's 400m semi-finals
There's British interest in the final 400m semi-final of the day and that's Martyn Rooney, who ran a season's best 44.45 to advance from the heats as one of the fastest losers.
South Africa's Wayde Van Niekerk the quickest on paper with a season's best 43.96.
'An elephant on your back'
Darren Campbell
Former British sprinter on BBC Radio 5 live
"Running the 400m is like an elephant has jumped on your back if you get it wrong. It's like watching people try to do the marathon when their legs go. The pain is ridiculous if you misjudge it."
'Yousif can't do much better than that'
Men's 400m semi-finals
Michael Johnson
BBC Sport athletics expert & 400m world record holder
"Rabah Yousif ran a very good race. It got really competitive around the curve but he held his own. It was 44.54 and it's a great race, a huge personal best and you can't do much better than that."
Yousif made to wait...
Yousif third and sets PB
Isaac Makwala wins in 44.11 and has enough energy for a few celebratory push-ups.Yousef Ahmed Masrahi (44.40) was second.
Britain's Rabah Yousif clocks a personal best 44.54 and he can do no more than that. It might be enough to progress as a fastest loser.
Men's 400m semi-finals
On the track, Britain's Rabah Yousif Bkheit is preparing to race in the second of the men's 400m semi-finals. Saudi Arabia's Yousef Ahmed Masrahi, who topped the time sheets in the heats, and Botswana's world leader Isaac Makwala are the men who will probably stand in his way of a place in the final.
Lavillenie clears 5.80m
In the men's pole vault we have first sight of Renaud Lavillenie. The bar is up to 5.80m and the Frenchman clears it as if the height is merely a few centimeters above the ground. He kisses his clenched fist. Why not?
The world record holder and two others - Pawel Wojciechowski and Piotr Lisek - are the only men who have so far cleared that height
'This is so easy'
Men's 400m semi-finals
Allison Curbishley
BBC athletics expert on Radio 5 live
"I love these rounds - you are trying to say to your rivals 'this is so easy'. Kirani James is hardly breathing. It will be hard but he's making it look so easy.
"This is a fast track - can they get close to Michael Johnson's world record? They will just be thinking of winning but there could be fireworks in the final."
'Sending out a message'
Men's 400m semi-finals
Steve Cram
BBC athletics commentator
"From the top of the home straight Kirani James was looking around and he was sending out a message. He was not going to let Luguelin Santos go past him."
James wins 400m semi in 44.16
The first two automatically through to the final and they are Kirani James and Luguelin Santos (44.26).
James was out of the blocks quickly and by the time they come out of the final bend he is in the lead. The Granadian has time to look over his shoulders, slow down slightly and cross the line first in 44.17, with Santos breaking the Dominican Republic's national record.
Bird's eye view from the Bird's Nest
Men's 400m semi-finals
Olympic champion Kirani James features in the first head and should easily as his season's best of 43.95 secos is head and shoulders above the rest. The 22-year-old James and his fellow semi-finalists being made to wait by the pole vaulters.

Men's pole vault final
We've neglected the men's pole vault, which features world record holder and Olympic champion Renaud Lavillenie. He's yet to win a world title, though, so could this be his year? The Frenchman has yet to jump, content to leave the others do their thing. Czech Michael Blaner currently leading with a 5.64m clearance.
'I'm disappointed in myself'
Phil Jones' interview with Britain's Asha Philip resembles a segment of 'I'm a Celebrity' as the sprinter yelps after being attacked by a flying bug. The Briton is made of tough stuff and carries on regardless. What a pro.
"I'm a bit disappointed in myself," she says. "I always want more. Getting injured not long before these championships was a bit of a mess, but I tried to give it a go.
"It's my second World Championships and I've made the semi-finals both times so hopefully one day I will make a final."
Schippers through to final in 10.83
Women's 100m semi-finals
From world-class heptathlete to world-class sprinter? It seems so. Dafne Schippers comes from behind, uses her power and strength to overpower her rivals in the latter stages and clocks a personal best 10.83.
Former world champion Veronica Campbell-Brown is second in 10.89, which means 2013 silver medallist Murielle Ahoure will not be in the final later this afternoon.
Women's 100m semis: Heat three

Who gets top billing?
Tom Fordyce
Chief sports writer in Beijing
"If you're trying to decide whether English Gardner is your favourite name in the women's 100m, it might be worth knowing that her US team-mate Tori Bowie's full first name is Frentorish."

Michael Bennett-Lee: Who can beat @realshellyannfp I really don't think there is anyone this lady is phenomenal.
Can Bowie challenge Fraser-Pryce?
Darren Campbell
Former British sprinter on BBC Radio 5 live
"I think Tori Bowie can challenge Fraser-Pryce in the final. Her technique is very smooth and if she can execute her start and drive phase she will come back on Fraser-Pryce and, if she is in the lead, I'm not sure Fraser-Pryce can catch her."
Bowie wins in 10.87
Tori Bowie the favourite to progress, and that isn't because she's got an A-lister's name. The American reacts fabulously, stumbles slightly coming out of the blocks, though, and doesn't relinquish the lead for the entirety of the race, clocking 10.87 to win.
Trinidad and Tobago's Kelly-Ann Baptiste is also through, coming second in 10.90.
Women's 100m semis: Heat two
Here's the line up for the second women's 100m semi-final. The semi-finalists being introduced to the crowd as I type so we will be under way shortly.

Fraser-Pryce through to final in 10.82
They step into the blocks, Briton Asha Philip takes a deep breath before crouching... the first two qualify automatically for the final...
Easy for Shelly-Ann Fraser-Pryce as she pumps the legs and overtakes her rivals from halfway to finish in 10.82 seconds. Joining her in the final will be Commonwealth champion Blessing Okagbare (10.89).
Asha PhIilip started well but was out of contention by the closing stages, finishing seventh in 11.21 secs.

Women's 100m semi-finals
What's next? The women's 100m semi-finals and another Jamaican sprinting great, Shelly-Ann Fraser-Pryce is pacing near her lane, waiting to explode into action.
The world and Olympic champion has been the the hairdresser for this championships and looks like a flower girl in technicolor - green dreads with sunflowers on her head. It grabs the attention.
'We are leaving today'
Jessica Ennis-Hill's coach Toni Minichello has been talking to BBC Sport. He says: "It was straight back to the hotel yesterday for packing as we are leaving today. Reggie has been waiting for his mum for the last two weeks so it's time to go home."
Describing the challenges he faced coaching Ennis-Hill after she gave birth 13 months ago, Minichiello added: "The running was superb from day one, the difficulty was doing stuff like jumping and bouncing.
"That was very difficult when we started and we had some Achilles issues to deal with as well. You learn as you are going along and do the best you can to make a compromise."
It has been slow progress - Minichiello
Jessica Ennis-Hill's coach Toni Minichiello is currently chatting to Gabby Logan on the telly, but earlier he was speaking to the good folk on BBC Radio 5 live.
"When she first came back to the sport it was very difficult with the power events and then we had injury issues, so it was slow progress, but when she got to the London Anniversary Games, it was there that we felt she should go," says Minichiello.
'Valiant effort from Beesley'
Women's 400m hurdles semi-finals
Michael Johnson
BBC Sport athletics expert & 400m world record holder
"Meghan went out really quickly and she would have to attack this and do the best she could. She is a slight athlete, very small, and lacking a bit of power that the other athletes have, but it was a valiant effort from her."
Beesely out but Child through
Is Meghan Beesley through to the 400m hurdles final as a fastest loser? Unfortunately not, her time of 55.41 not quite good enough, but Eilidh Child is through as a fastest loser.
America's Shamier Little is also through as a fastest loser, and hopefully she will wear that eye-catching bow in her hair in the final.
Beesley third, Hejnova wins
Ouch. Smash, bang, wallop. America's Kori Carter runs into a barrier and she's gone, gone gone.
Meghan Beesley finishes third, with the world champ Zuzana Hejnova strolling over the line in first with Jamaica's Janieve Russell second.
Beesley gunning for the final
British eyes on Meghan Beesley in lane four as she prepares to run and hurdle in the final semi-final. The Briton ran a personal best 54.42 to qualify from the heats, but is up against world champion Zuzana Hejnova in this ding-dong.
'I'm so upset'
Women's 400m hurdles semi-finals
Child is downbeat, but there's still hope as she is currently the quickest loser with one more semi-final to come...
Petersen beats Spencer
The great Kaliese Spencer controlling the race early on, but is passed by Denmark's Sara Slott Petersen (54.34) with 20m or so to go. What happened to Shamier Little? The American and her bow crossed the line in third in 54.86, an iffy hurdle coming out of the bend costly.
It was a fairly slow race, which is good news for Eilidh Child, says Steve Cram in the commentary box.
Women's 400m hurdles semis
The second women's 400m hurdles semi-final is upon us and although there is no Briton racing that does not mean we're not interested, mainly because we want to see if Shamier Little's radioactive green bow stays on top of her head for the entire lap.
It's an incredible accessory to wear during the heat of battle, but why not add extra glamour to such occasions?
'Back to the drawing board'
Women's 400m hurdles semi-finals
Colin Jackson
Two-time world 110m hurdles champion
"Eilidh Child will be disappointed with that performance. She would have been looking at this list and thought she could make it through.
"But the problem was with hurdles six and seven and she took hurdle eight on her wrong leg. It was just off sync for her and it is back to the drawing board. But she could still get through as a fastest loser."
Child third in first semi-final
As the bookies' would have predicted, Eilidh Child, Cassandra Tate and Wenda Nel coming round the final bend together. Child slightly ahead... but she's overtaken by eventual winner Tate (54.33 seconds) and Nel, the Briton stuttering on the final couple of hurdles.
Child (54.80 seconds) must now wait to find out if she is one of the two fastest losers.
Women's 400m hurdles
The first two in each semi-final will qualify, plus the two fastest losers. Should European champ Eilidh Child qualify, it would be her second successive final at the World Championships.
On paper, the Scot is the third quickest this year of the line-up, behind America's Cassandra Tate and South Africa's Wenda Nel.
Coming up
For those of you who like graphics and a bit of detail on your schedule then this one's for you. Briton Eilidh Child (lane 5) is in the first 400m hurdles semi-final. The Scot sipping juice as she waits to be called into position.
Day three schedule
I guess we should focus on the day ahead. Five gold medals to be won, the fastest women on the planet on show - this is how it will all unfold:
12:00 men's javelin throw (qualification, Group A)
12:05 men's pole vault final
12:10 women's 400m hurdles semi-finals
12:30 women's triple jump final

'Hopefully I can compete with these guys'
More quotes from British sprinter Adam Gemili who feels he has learned a lot by watching the best sprinters in the 100m final.
He tells BBC Sport: "I'm always learning and improving. Hopefully as I get older I can go out and compete with these guys. I just have to train hard. If I was out on the start line hopefully I would've got into the final but it was not to be."
'A wicked experience out here'
British sprinter Adam Gemili, who is out in China, but will not compete in the 4x100m relay because of injury, has been talking to BBC Sport.
He says: "My injury is better now, it's more a precaution to not run. We've got a few big years coming up but if I went out and did something silly then that would put me further back.
"Watching last night's 100m was so cool. It has been a wicked experience out here. With Bolt you always have to believe in this guy and never write him off. Gatlin just fell apart but what a race to witness."

"Christine Ohuruogu is a solid performer and has relied on that throughout her career. She is not one of the fastest runners this year but will use this race to get into shape.
"She ran a very even-paced race. She has got really good technique, is a very powerful runner and has great upper-body strength. If there is any athlete that I don't worry about, it is Christine. She will always be right there."
What have you missed?
While you were hopefully tucked up in bed, a few British athletes were making progress in Beijing.
Olympic long jump champion Greg Rutherford reached Tuesday's final, finishing second in qualifying.
Defending champion Christine Ohuruogu moved on to the 400m semi-finals by winning her heat, with fellow Briton Anyika Onuora also going through in a personal best time of 51.14secs.
And Holly Bradshaw recorded a season's best of 4.55m to finish joint top of qualifying in the pole vault.

'Can I see this girl coming back? I'm not certain'
It wasn't only sport scientists and former athletes who doubted whether Jessica Ennis-Hill would be the heptathlete of old. There was a time when her coach Toni Minichiello wasn't so sure...

"What an amazing role model Jessica Ennis-Hill is. It is about building back from having a baby.
"She has had to build up her training and do everything right, but she has peaked at the right time. She said she would be happy with a bronze medal but what an amazing job she did.
"She is so happy being a mum and her son is going to be so proud of her."
Super mum, super athlete
Sometimes no words are necessary. The Guardian sum up Jessica Ennis-Hill's feats in one glorious image.
Sean Ingle writes: "Only a handful of women have celebrated a world title after giving birth, and the majority of those have come in endurance races, where pregnancy may confer some benefits. But in the heptathlon? Never."

Thirteen months after giving birth to her son Reggie, Ennis-Hill is now a world champion. A remarkable achievement.

What the papers say
Daily Mirror
It's that man again, the one who saved athletics. "Usain Bolt gave the gift of life to athletics as he produced surely his greatest win to raise the sport from its death bed," writes Alex Spink in the Daily Mirror.
Lord Coe enjoys himself
What the papers say
I think it's universally agreed among headline writers that Usain Bolt is the saviour of athletics.
"Usain Bolt rode to the rescue of his beleaguered sport once again as he dashed Justin Gatlin's hopes of 100 metres gold at the World Championships in Beijing," says Guy Aspin in the Independent.
'Impossible to ban for life'
Michael Johnson
BBC Sport athletics expert & 400m world record holder
"Usain Bolt does feel responsible and people were depending on him. People appreciate him and what he brings to the sport. He is an entertainer but he takes the sport very seriously.
"It is impossible to ban people for life. That is what the fans want, but legally it is not possible so we will have to accept that drug cheats will come back into the sport. For the fans of this sport, the sentiment was they would have preferred it if Justin Gatlin had gone out in the first round."

Mind games and fistbumps
Tom Fordyce
Chief sports writer in Beijing
"On the morning after the night before, all the talk in Beijing - or at least in the sporting bubble around the Bird's Nest - has been of a 100m final that still has all who saw it shaking their heads in wonder.
"Why did Gatlin fall apart? Where did Bolt find the self-belief? How critical were the mind games that the Jamaican tried on his rival as they warmed up?
"There is even a theory it came down to a fistbump, offered by Bolt to his rival seconds before gun. Linford Christie once growled like an angry bear at Carl Lewis when he tried the same thing before a World final. Gatlin, nonplussed, accepted it - and in that moment, goes the theory, subconsciously ceded control and authority to the great champion."
Did Bolt save athletics?
0.01 seconds between good and bad?
The 100m final was close, there was hardly anything in it, just a hundredth of a second separating Usain Bolt and his rival Justin Gatlin but that was enough for gold in what has been described as the six-time Olympic champion's greatest performance of all.
Gatlin was the favourite, he'd run the four quickest times of the year, but that accounted for nothing in Beijing. They don't give gold medals based on Diamond League performances, and the majority of the world is happy about that.
"0.01 secs between good and evil as Bolt pips drugs cheat," headlined the Daily Mail today.
What the papers say
Unsurprisingly, Usain Bolt and Jessica Ennis-Hill dominate the back pages of this morning's national papers. "The day athletics smiled again," headlines the Daily Telegraph.
BBC Coverage
Live coverage has started online and on BBC Two with Gabby Logan, Michael Johnson and Jo Pavey. They'll be with you all afternoon. (Hang on, no Daley Thompson? Where's Daley?!)
The greatest miracle of all?
Tom Fordyce
Chief sports writer in Beijing
Was Bolt's victory on Sunday his greatest miracle, asks our chief sports writer Tom Fordyce.
"Once again, Bolt proved us all fools," he writes. "On a night that could have ended with the sport no longer teetering on the abyss but plummeting over it, the victories of Bolt and, a few hours earlier, Jessica Ennis-Hill in the heptathlon, gave the believers something to cling to and the doubters reason to perhaps think again."
Post update
Hello! Welcome to live coverage of the third day of the World Championships in Beijing, but we can't talk about today until we reflect on a wonderful yesterday.
Jessica Ennis-Hill produced the mother of sporting comebacks by winning heptathlon gold while Usain Bolt pulled off what seemed impossible, beating Justin Gatlin, a two-time drug cheat and the dominant force of sprinting in the last two years. Incredible performances from incredible athletes.
Post update
The sun rose again this morning, as it always does, and the clocks continue to tick. Everything seems the same, but something's a little different. Worriers are smiling, skeptics are filled with hope. The smiling assassins of cynicism triumphed in Beijing yesterday and dark clouds are gradually disappearing.
