Usain Bolt coasted across the finish line in his 200 meters heat.

The defending Olympic champion did his trademark pose and other animated antics during introductions.

Then he did what he always does. He ran fast and dominated the competition.

He was already ahead of the field as he came off the turn, and then cruised home from there. He actually let up at the end.

Another day at the office for the world's fastest man.
