The fastest man in the world, who holds the world record in the 100m, 200m and the 4x100m relay and won gold in all of those events at Beijing 2008 and London 2012, Bolt is attempting to pull off an unprecedented 'triple triple'. If he achieves this feat, he will cement his name as the greatest sprinter in history. Bolt admitted to some anxiety ahead of his heat.

"I was nervous because the 200m is my favourite event. I didn't want to go out. I've recovered from the 100m. I'm tired now, but happy to be through. I'm looking forward to tomorrow (the semi-finals, Wednesday 17 August)."
