It was a semifinal heat, and heat was what Usain Bolt brought. Again.

He took the 200-meter on Wednesday night with a confident stride that, to the average observer, looked as if he wasn't really working very hard. Everyone else struggled to catch up with him as he led the vanguard to the finish line, making one of the Olympics' most intense sprints look like his evening jog.

Earlier, Bolt walked to the starting line with his usual combination of smiles, salutes and struts. It was only three days ago that he set a new Olympic record for the 100-meter, beating his own Olympic time but still not besting his personal fastest time, which also happens to be the world record.
