Usain Bolt secured his second hat-trick of sprint gold medals as Jamaica won the 4x100m relay in a new world record time of 36.84 seconds.

Having already become the first man in Olympic history to do a sprint double double – winning both the 100m and 200m at consecutive Games – the world’s fastest man then rounded off a dream tournament for Jamaica as he anchored them to victory over the United States in the relay.

After two legs, the United States held a narrow advantage, but on leg three 100m world champion and Olympic silver medallist Yohan Blake went past Tyson Gay, before passing the baton on to the imperious Bolt, who raced away from Ryan Bailey to cross the line in a new record time.

Bolt then celebrated by performing a Mo Farah ‘Mobot’ celebration as he crossed the line.

Although it is a team event, inevitably it was Bolt who received most attention and praise after the race – not surprising considering he has now entered the ranks of the all-time great Olympians for his medal-winning exploits as well as his performances.

When asked about the prospect of completing a ‘treble-treble’ at the 2016 Rio Olympics, Bolt said he thought it would be pretty unlikely.

‘I’ve thought about it but I think it’s going to be very hard because Yohan, he’s just come into the game and he’s running pretty well, and I’m sure there’s going to be a lot more cats coming up to run,’ he said.

‘I’m just happy. I’ll take it a step at a time.’

Bolt’s sixth gold medal puts him in elite company – only three athletes in Olympic history have won five or more gold medals, the others being Ville Ritola (five, 1924-28),  Ray Ewry (eight, 1900-08) and Carl Lewis (nine, 1984-96).
