Rio Olympics: Usain Bolt wins; GB golds for Whitlock, Murray, Rose & Kenny

Usain Bolt claimed a record third 100m title while tennis player Andy Murray won Britain's fifth Rio gold medal on GB's best day at an overseas Olympics.

A 15th gold of the Games, putting GB second in the table, followed gymnast Max Whitlock's historic double win and Justin Rose's golf victory.

Cyclist Jason Kenny defeated team-mate Callum Skinner for his fifth title.

Bolt, 29, ran 9.81 seconds to beat Justin Gatlin to gold and follow up his titles at Beijing 2008 and London 2012.

The Jamaican remains on course for the sprint 'treble treble', with the 200m and the 4x100m relay to come.

"I expected to go faster, but I'm happy I won," he said. "I did what I had to."

South African Wayde van Niekerk broke Michael Johnson's 17-year-old world record by 0.15secs to win 400m gold in 43.03. The mark stood for 6,198 days.

Wimbledon champion Murray, 29, retained his Olympic title with an epic four-set win over Argentina's Juan Martin del Potro.

Britain secured five golds, and their three silvers included one for windsurfer Nick Dempsey to keep the team well on track for their Rio medal target of 48.

GB won six gold medals on 'Super Saturday' at London 2012 - the best one-day haul since eight were won in 1908.

Sailor Giles Scott is guaranteed gold in the men's Finn class, while boxer Joshua Buatsi will win at least a bronze.

But there will be no third Olympic medal for Christine Ohuruogu, champion in 2008 and silver medallist at London 2012.
