The 2015 World Championships come to an end, leaving us with fantastic memories. Usain Bolt overcame Justin Gatlin to prove he's the best that's ever been; Jessica Ennis-Hill proved she's a super mum; Greg Rutherford proved he's a worthy champion while Mo Farah proved he can make history again and again.
Thanks, as always, for joining us. Until next time...

On the 4x100m relay debacle
Neil Black is asked about Britain's sprint relay team and Richard Kilty's tweets suggesting there's disharmony in the team and that CJ Ujah should not have run the last leg.
"We shouldn't judge Richard Kilty in the heat of the moment when he is disappointed and upset," says Black. "We came to win medals in all four relays, we did that in two. That's a pretty good record.
"We're not concerned. We've got high standards. We were not going to settle for fifth, sixth or seventh, so we went for a medal.
"We take risks to win medals. It didn’t work out but we’d do it again. We move on and stay positive."
Medal haul 'what we expected'
Asked about Britain's medal haul of four golds, a silver and two bronzes, Neil Black says: "This is about what we expected. We’re looking to win medals and this is there or thereabouts.
"We’re happy with how people have performed on a global level. And those fourth, fifth and sixth places are brilliant and that’s what we were expecting in Beijing. It's on the road to the Rio Olympics and London Worlds in 2017."
'Unbelievable championships'
Neil Black's summation
Neil Black, Britain's performance director, says the championships "couldn't be better".
He tells Gabby Logan: "There have been brilliant performances over the whole competition with some of our established stars producing again.
"And then some of our young people in new events are being competitive. It's been an unbelievable championships and we are really happy and proud."

Britain's best ever
BBC SportCopyright: BBC Sport
Britain's previous best gold-medal haul was three in Stuttgart in 1993 and Moscow in 2013. The Super Saturday gang - Mo Farah (2), Jessica Ennis-Hill and Greg Rutherford - have made Beijing the team's most successful championships yet.
Bronze Rooney?
Martyn Rooney joked he would call his son Bird's Nest Rooney, here is what hos wife had to say...

I can't wait to meet him. from Britain's Martyn Rooney. 4x400m bronze medallist

I did not want to go home empty handed, I wanted to bring something back to my wife to make it worthwhile. Hopefully she is proud of what I have done. I can't wait to meet him.
Baby and medal celebrations
What should Martyn Rooney call his newborn son? Phil Jones says some have suggested the 400m runner should name his first born after the 400m world champion Wayde van Niekerk. That would, of course, mean a Wayde Rooney has entered the world.
Rooney, diplomatically, says there's nothing wrong with the name Wayde but says he's unlikely to name his son after the South African.
Kenya's gold rush
Britain fourth in medal table
Britain end the championships fourth in the medal table with a total of seven medals and four golds - which is the team's most successful golden haul.
Kenya are numero uno - 16 medals in total, including seven gold ones.

Martyn Rooney wasn't initially in the British team, but a successful appeal ensured he made it to Beijing and he was then named team captain. Representing his country did mean he missed the birth of his first child, though.

By the time it comes to the final 10m the Jamaican runs out of steam, which allows Martyn Rooney to pip him to win bronze for Britain.

But Gianmarco Tamberi touches the bar at 2.29m and gravity does the rest. That's the last we'll see of the Italian and his half-and-half beard at these championships. Seventh place as good as it gets for Tamberi, but at least he gets to look in the mirror and see that beard every day

Attention hipsters!
Taking hipster to the extreme is high jumper Gianmarco Tamberi. The Italian sported the half-and-half beard at the European Indoor Championships, continued to do so at this summer's Anniversary Games and has stuck with it for Beijing. Why not, I suppose? When a look works then it works...

'Farah lives physical nightmare most days'
Tom Fordyce
Chief sports writer in Beijing
APCopyright: AP
Our chief sports writer Tom Fordyce has brilliantly explained why Mo Farah's victories are anything but routine.
"The 5,000m makes sense to a lot of ordinary Britons. Thousands run the distance at a Parkrun every weekend, some with PBs in mind, others with dogs on a lead or kids in tow," writes Tom.
"But those segments of Farah's are not incomprehensible only to the happy Saturday-morning dabblers. Farah's was a last mile that half the entrants in the men's 1500m would have been unable to live with. It was a last half-mile that half the 800m field would have struggled with too."
But back to Mo Farah for a moment, who is on the front page of The Times. Apparently the Briton should consider making arrangements for a visit to Bucks Palace. "Knighthood beckons after 'triple double' gold," is their headline.

Usain Bolt is preparing to step up onto the highest podium of all to collect his 11th world title.

GB's relay record
BBC SportCopyright: BBC Sport
Britain's track record on the sprint relay does not make happy reading.
"What A Mo-Ment!"screams the front page of the Independent.
"Farah was serene, steering clear of the trips that had nearly derailed him in the 10,000m and 5,000m heats for another dominant victory," writes Matt Majendie in the paper.
The IndependentCopyright: The Independent
What does Farah think?
Responding to Brendan Foster's comments, Farah said it was "amazing" to be in the same category as greats such as, erm, David Beckham.
"We have had so many legends and to be in the same category as them is amazing," he said. "It's great to make history."
Getty ImagesCopyright: Getty Images
Britain's greatest sportsman?
Brendan Foster thinks he is, but is Mo Farah Britain's greatest sportsman?
"He's Great Britain's most prolific winner of global golds and he's put former British athletes like Sebastian Coe and Daley Thompson behind him," Foster argued on BBC Radio 5 live.
"Former rower Sir Steve Redgrave [who won five Olympic golds] was part of a team. Mo is on his own and it's lonely out there. He's ruthless and we've not seen that. We should be enjoying the moment. We'll never see his like again."

Farah homeward bound
Sometimes a series of emoticons say it all... Britain's Farah is heading home to reunite with his pregnant wife and children. Hopefully banners and bunting are hanging from every wall and ceiling at Farah towers.
What the papers say
"Arise, Sir Mo," says the Daily Telegraph on its back page.
"Since his 5,000m gold in Daegu in 2011 he has been a champion beyond compare, reeling off an unprecedented seven successive victories, including glorious double distance titles in London, Moscow and now Beijing," writes Oliver Brown the Daily Telegraph.
Daily TelegraphCopyright: Daily Telegraph
The 'triple-double'
But before we focus on the day's action, there's a certain triple-double to talk about. Mo Farah did it, as everyone thought he would, becoming the first man in history to pull off a distance 'triple-double'.
The Briton has now won three successive world 5,000m titles and has won golds in both track distance events at the Olympics and two World Championships.
It is something not even the great Ethiopian Kenenisa Bekele achieved, the only other person to claim an Olympic and world 'double-double' in the 5,000m and 10,000m. Simply brilliant.

Post update
Hello! Yes, it's true, this is the final day of the World Championships in Beijing. There's no point trying to stop the inevitable, but it doesn't mean we can't make the most of the remaining few hours we have and relish watching the best in the world competing for the last six medals on offer.
Post update
The triple-double - magnificent in whatever shape or form it comes in.
On a plate it can be the tastiest, juiciest burger. In a cone? Taste-bud exploding, towering scoops of ice cream.
On the track, it's an incomparable feat, achieved by only the greatest.

Usain Bolt has posted a picture on Instagram with his 4x100m relay champions. "Golden Relay Squad out and bad," the 11-time world champion writes.
Medal ceremony
Former IAAF president Lamine Diack will present the final medals of the day to the 4x400m relay top three.
Britain's quartet on the podium, of course, and Martyn Rooney seems delighted with his miniature mascot, waving it in the air to someone whose attention he's caught in the crowd. That's a gift for baby Rooney.

On this day...
Who are Britain's future stars?
The future is looking bright, so they say, but who are the young athletes who could star for Britain in future championships?

On the 4x100m relay debacle
Neil Black is asked about Britain's sprint relay team and Richard Kilty's tweets suggesting there's disharmony in the team and that CJ Ujah should not have run the last leg.
"We shouldn't judge Richard Kilty in the heat of the moment when he is disappointed and upset," says Black. "We came to win medals in all four relays, we did that in two. That's a pretty good record.
"We're not concerned. We've got high standards. We were not going to settle for fifth, sixth or seventh, so we went for a medal.
"We take risks to win medals. It didn’t work out but we’d do it again. We move on and stay positive."
Medal haul 'what we expected'
Asked about Britain's medal haul of four golds, a silver and two bronzes, Neil Black says: "This is about what we expected. We’re looking to win medals and this is there or thereabouts.
"We’re happy with how people have performed on a global level. And those fourth, fifth and sixth places are brilliant and that’s what we were expecting in Beijing. It's on the road to the Rio Olympics and London Worlds in 2017."
'Unbelievable championships'
Neil Black's summation
Neil Black, Britain's performance director, says the championships "couldn't be better".
He tells Gabby Logan: "There have been brilliant performances over the whole competition with some of our established stars producing again.
"And then some of our young people in new events are being competitive. It's been an unbelievable championships and we are really happy and proud."

Britain's best ever
Britain's previous best gold-medal haul was three in Stuttgart in 1993 and Moscow in 2013. The Super Saturday gang - Mo Farah (2), Jessica Ennis-Hill and Greg Rutherford - have made Beijing the team's most successful championships yet.
Bronze Rooney?
Martyn Rooney joked he would call his son Bird's Nest Rooney, here is what hos wife had to say...
Rooney 'incredibly happy'
Baby and medal celebrations
What should Martyn Rooney call his newborn son? Phil Jones says some have suggested the 400m runner should name his first born after the 400m world champion Wayde van Niekerk. That would, of course, mean a Wayde Rooney has entered the world.
Rooney, diplomatically, says there's nothing wrong with the name Wayde but says he's unlikely to name his son after the South African.
Kenya's gold rush
Britain fourth in medal table
Britain end the championships fourth in the medal table with a total of seven medals and four golds - which is the team's most successful golden haul.
Kenya are numero uno - 16 medals in total, including seven gold ones.
Child delighted with bronze
Rooney's the Daddy
Martyn Rooney wasn't initially in the British team, but a successful appeal ensured he made it to Beijing and he was then named team captain. Representing his country did mean he missed the birth of his first child, though.
Post update
Two bronze medals for Britain in the 4x400m relays and the women's team are talking to Phil Jones on the telly. Christine Ohuruogu wearing fetching headgear - a union bow. A national flag simply won't do these days.

USA win 4x400m gold, Britain take bronze
Oh my word! Jamaica's Javon Francis presses some sort of booster button with 250m remaining, overtaking LaShawn Merrit to take the lead with the speed of a 200m runner... Astonishing. Foolish? Yep. By the time it comes to the final 10m the Jamaican runs out of steam, which allows Martyn Rooney to pip him to win bronze for Britain.
LaShawn Merritt guides America to gold in 2:57.82, while Trinidad and Tobago claim silver in a national record 2:58.20.
USA First, Britain third...
Tony McQuay puts the Americans in first spot... Britain third going into the third leg.

Men's 4x400m relay final
The Americans steal the show again during introductions for the 4x400m relay with a baseball themed 'celebration'. These posturings are nice additions to the championships.
Britain? They nick Brazilian Bebeto's 'baby' goal celebration during the 1994 World Cup, a nod to captain Martyn Rooney who has recently become a father.
Drouin wins high jump gold
The bar has been lowered to 2.34m in the high jump jump-off and Canada's Derek Drouin is the only man to clear the height, and he did so comfortably.
The 2013 world champion Bohdan Bondarenko and China's Zhang Guowei will share silver.

Men's high jump final - jump-off
There's a jump off in the men's high jump final. Birthday boy and defending champion Bohdan Bondarenko, Canada's Derek Drouin and China's Guowei Zhang will battle for gold.
All have three failures at 2.36m, but as all have cleared all previous heights on their first attempts they go again at 2.36m.
Drouin and Bondarenko fail on 2.36m again...
Men's high jump final
There will be no medal for Qatar's Mutaz Essa Barshim in the men's high jump, which is a shock. The world leader coming to Beijing, whose personal best 2.43m is the equal third highest of all-time, fails at 2.36m.
'What a surprise'

Britian's split times:
Ohuruogu: 51.1 seconds

Child: 50.6 seconds

Bronze for Britain
A brilliant bronze for Britain as 20-year-old Seren Bundy-Davies holds her position and crosses the line with a big distance between her and the rest. A season's best 3:23.62 for the British quartet who are smiling and jumping on the finishing line.
Jamaica win 4x400m relay gold, Britain bronze
The USA in first spot coming down the home straight... but Jamaica's Novlene Williams-Mills closes down Francena McCorory and overtakes her with 10m to go! Gold for Jamaica in 3:19.13.

Brit Grice ninth in 1500m
Kenya's Elijah Motonei Manangoi makes a late dash to the line to secure silver in an excitingly finish, clocking 3:34.63. Morocco's Abdalaati Iguider takes bronze (3:34.67). Britain's Charlie Grice was ninth in 3:36.21.
Kiprop defends 1500m title
Brilliant. Brilliant. Brilliant. With 1200m the finalists step ion the accelerator... the Kenyan trio are behind coming into the final bend..
Asbel Kiprop seems a long way from glory, in about 10th with 300m to go, but he extends his stride, moves up the field around the bend... he's into the top three down the home straight and those long legs move him past Abdalaati Iguider and Taoufik Makhloufi. Kiprop home in 3:34.40
Men's 1500m final
Kenya aiming for a top three in the 1500m. Asbel Kiprop, the two-time reigning champion, would be most people's favourite. Timothy Cheruiyot leading the way coming towards the 800m mark. Kiprop lurking...
Men's 1500m final
The men's 1500m final is next up. Alas there is no Ovett, Coe or Cram representing Britain but there is a Brit in the line-up and that's Charlie Grice, the fourth fastest of the 12 finalists.
Here's how they line up:
Barshim takes lead, Tamberi out
Mutaz Essa Barshim has retaken the lead in the men's high jump final, clearing 2.33m on his first attempt.
But Gianmarco Tamberi touches the bar at 2.29m and gravity does the rest. That's the last we'll see of the Italian and his half-and-half beard at these championships. Seventh place as good as it gets for Tamberi, but at least he gets to look in the mirror and see that beard every day
'Dibaba gave up'

Brit Twell 12th in 5000m
Where did Britain's Stephanie Twell finish? I can help with that, she was 12th in 15:26.24. The experts in the commentary box think that's a fine effort.
Championship record for Ayana
Almaz Ayana's winning time was 14:26.83 - a championship record which breaks Tirunesh Dibaba's previous championship best. It's not been a great 15 minutes for the Dibaba family.
Dibaba outsprinted for silver
Everyone thought she would win gold but Genzebe Dibaba must settle for bronze. By the time she realises Senbere Teferi is on her heels it's all too late. There's a last-minute kick from Dibaba but there's no reserves of energy left and she's beaten to silver by her compatriot for an Ethiopian top three.
Ayana wins 5000m gold
The final bell rings and Almaz Ayana is on course for victory, she's beaten Genzebe Dibaba with those punishing quick laps in the middle of the race.
Time to celebrate?
An interesting celebration from China's Guowei Zhang as he clears 2.29m in the high jump to go third. He must have watched the Karate Kid last night for celebration ideas.
Women's 5000m final
Ethiopia's Almaz Ayana has upped the tempo in the 5000m final, her plan is to sap Genzebe Dibaba's energey, negating her kick at the end. A 65-second lap and they go through 3000m in 8:55.63.
Dibaba is being tested because there's oodles of space - about 20m - between Ayana and Dibaba. What a finish this is going to be.
Women's javelin final
Oof it's close in the women's javelin final - only 2cm separating leader Kathrina Molitor of Germany (64.74m) and China's Huihui Lyu, who has produced a season's best 64.72m.
Women's 5000m final
Japanese duo Misaki Onishi and Ayuko Suzuki setting the pace, completing the first 1000m of the 5000m final in three minutes.

The first track event of the day is about to start and, just as in the men's 5,000m on Saturday, history could be made.

Men's high jump final
Heights of 2.20m and 2.25m are easy for favourite Mutaz Essa Barshim, who clears them both on his first attempt. Although he has just failed at 2.29m.
Defending champion Bohdan Bondarenko also went over 2.25m on his first attempt.
Day Nine schedule
For the final time this week, we bring you the daily schedule. (Let's not get tearful so early on, please)

Men's high jump final
High jump (11:30 BST)
There might be a familiar name and face to cricket fans when the high jump gets underway.
That's because Brandon Starc of Australia is competing. He's the younger brother of cricketer Mitchell, who struggled against England in the recent Ashes series.
Hopefully the bar doesn't tumble as frequently this afternoon as Australian wickets...
Attention hipsters!
Taking hipster to the extreme is high jumper Gianmarco Tamberi. The Italian sported the half-and-half beard at the European Indoor Championships, continued to do so at this summer's Anniversary Games and has stuck with it for Beijing. Why not, I suppose? When a look works then it works...
The Italian says his trademark beard is to entertain the audience. It is entertaining, Gianmarco... Definitely.
Kenya on top
Medal table
What does the medal table look like? Kenya are still on top as they have been for most of the week, while Britain are fourth thanks to Mo, Jess, Greg and Shara.
What you might have missed
There was only one event happening in Beijing while the owls and badgers were roaming Britain's fields undisturbed and carefree and that was the women's marathon.
Ethiopian Mare Dibaba won the gold medal, outsprinting Helah Kiprop to beat the Kenyan by one second. It was exciting watching them both enter the stadium together. Feel free to watch Dibaba's brilliant finish by clicking here.
'Farah lives physical nightmare most days'
Tom Fordyce
Chief sports writer in Beijing
Our chief sports writer Tom Fordyce has brilliantly explained why Mo Farah's victories are anything but routine.
"The 5,000m makes sense to a lot of ordinary Britons. Thousands run the distance at a Parkrun every weekend, some with PBs in mind, others with dogs on a lead or kids in tow," writes Tom.
"But those segments of Farah's are not incomprehensible only to the happy Saturday-morning dabblers. Farah's was a last mile that half the entrants in the men's 1500m would have been unable to live with. It was a last half-mile that half the 800m field would have struggled with too."
Read more of Tom's piece by clicking here.
What the papers say
But back to Mo Farah for a moment, who is on the front page of The Times. Apparently the Briton should consider making arrangements for a visit to Bucks Palace. "Knighthood beckons after 'triple double' gold," is their headline.
Men's 4x400m relay
The one-lap experts will, as is tradition, bring these championships to a close at 13:25 (BST) and Britain's 4x400m relay team has just been announced and making the line-up are Rabah Yousif, Delano Williams, Jarryd Dunn and Martyn Rooney.

Sprint relay medal ceremony
Usain Bolt is preparing to step up onto the highest podium of all to collect his 11th world title.
But while the Jamaican and his team-mates are waiting, a Canadian sprinter - whose team won bronze - is having a sneezing fit. He then shakes the hand of Jesse Owens' granddaughter, who is awarding the medals, without using wet wipes first. I'm not saying anything...
GB's relay record
Britain's track record on the sprint relay does not make happy reading.
GB 4x100m failure fallout
Should we mention the sprint relay and Britain's failure to get the baton around the track?
What the papers say
"What A Mo-Ment!"screams the front page of the Independent.
"Farah was serene, steering clear of the trips that had nearly derailed him in the 10,000m and 5,000m heats for another dominant victory," writes Matt Majendie in the paper.
What does Farah think?
Responding to Brendan Foster's comments, Farah said it was "amazing" to be in the same category as greats such as, erm, David Beckham.
"We have had so many legends and to be in the same category as them is amazing," he said. "It's great to make history."
Britain's greatest sportsman?
Brendan Foster thinks he is, but is Mo Farah Britain's greatest sportsman?
"He's Great Britain's most prolific winner of global golds and he's put former British athletes like Sebastian Coe and Daley Thompson behind him," Foster argued on BBC Radio 5 live.
"Former rower Sir Steve Redgrave [who won five Olympic golds] was part of a team. Mo is on his own and it's lonely out there. He's ruthless and we've not seen that. We should be enjoying the moment. We'll never see his like again."
Farah homeward bound
Sometimes a series of emoticons say it all... Britain's Farah is heading home to reunite with his pregnant wife and children. Hopefully banners and bunting are hanging from every wall and ceiling at Farah towers.
What the papers say
"Arise, Sir Mo," says the Daily Telegraph on its back page.
"Since his 5,000m gold in Daegu in 2011 he has been a champion beyond compare, reeling off an unprecedented seven successive victories, including glorious double distance titles in London, Moscow and now Beijing," writes Oliver Brown the Daily Telegraph.
The 'triple-double'
But before we focus on the day's action, there's a certain triple-double to talk about. Mo Farah did it, as everyone thought he would, becoming the first man in history to pull off a distance 'triple-double'.
The Briton has now won three successive world 5,000m titles and has won golds in both track distance events at the Olympics and two World Championships.
It is something not even the great Ethiopian Kenenisa Bekele achieved, the only other person to claim an Olympic and world 'double-double' in the 5,000m and 10,000m. Simply brilliant.
Post update
Hello! Yes, it's true, this is the final day of the World Championships in Beijing. There's no point trying to stop the inevitable, but it doesn't mean we can't make the most of the remaining few hours we have and relish watching the best in the world competing for the last six medals on offer.
Post update
The triple-double - magnificent in whatever shape or form it comes in.
On a plate it can be the tastiest, juiciest burger. In a cone? Taste-bud exploding, towering scoops of ice cream.
On the track, it's an incomparable feat, achieved by only the greatest.
