Winner of men's 100m sets new world record, 9.69 seconds
Usain Bolt powered to a new world record as he produced a stunning run in the Olympic 100m final.
Bolt was well clear at 60m and although he eased down and started to celebrate 15 metres from the line he still set a new mark of 9.69 seconds.
Richard Thompson finished second while American Walter Dix came third but they were yards behind the Jamaican.
That was an incredible race to watch.
