Usain Bolt may have come from behind to take his heat 10:07 but he looked VERY relaxed about it.
The Estadio Olimpico erupted when the fastest man in the world took to the start line for round one of the 100 metres in Rio.
And the Jamaican seemed to be toying with the rest of the field as he basically stopped trying three quarters of the way through and cheekily looked around.

Anyone else get the sense Usain Bolt is speed-walking through these heats?

Great Britain's James Dasaolu was in the same heat, running next to Bolt and finishing in third. But he'll have to wait to see if he qualifies for the next round as a fastest loser.
