Usain Bolt successfully defended his 100m title, breaking the Olympic record with a time of 9.63seconds and in the process, the Jamaican tamed his training partner Yohan Blake.

The 25-year-old delivered once again on the biggest stage of them all, recovering from a slow start to win easily and silence the doubters who had been questioning his fitness before London 2012.

Blake, surely the one to take over Bolt’s mantle when he hangs up his spikes, won the silver in a time of 9.75sec. Former Olympic champion American Justin Gatlin ran 9.79sec and  took the bronze, with team-mate Tyson Gay finishing fourth.

The third Jamaican in the final, former world-record holder, Asafa Powell pulled up and finished back in eighth place.

A vintage final looked on the cards when seven of the eight qualifiers for the final ran sub ten-second times in  the semis.

Bolt was only the third fastest but won easily in 9.87, slowest out of the blocks but still able to ease off for the final third. Gatlin was the quickest in 9.82, Blake – a training partner of Bolt nicknamed ‘The Beast’ – clocking 9.85.

British trio Adam Gemili, Dwain Chambers and James Dasaolu all missed out on the final.

Gemili, 18, recovered from a poor start to snatch third on the line behind Blake and Gay in 10.06, while Chambers (10.05) was fourth in his semi and tenth fastest overall and Dasaolu (10.18) seventh in the first semi.
