Olympic Daily Preview - Thursday, August 9th

London, England (Sports Network) - Jamaican sprinting star Usain Bolt will try to captivate the crowd at Olympic Stadium with another historic performance as the London Games hit Day 13 on Thursday.

Bolt will aim for his fifth Olympic gold medal when he races in the 200-meter final. Four years ago in Beijing, he won gold in the men's 100, 200 and 400- meter relay and he's already won the 100 here in London. Bolt joined Carl Lewis of the United States as the only men to win consecutive 100 golds and no man has ever claimed two Olympic titles in the 200.

Once again, the biggest threat to end Bolt's run of gold is expected to come from his countryman Yohan Blake, who beat Jamaica's national hero in both the 100 and 200 earlier this summer at the country's Olympic trials.

Bolt easily qualified for the final of the 200 on Thursday with a time of 20.18 seconds. Blake had the best time of the three heats, running the half- lap in 20.01 seconds. American sprinter Wallace Spearmon was next after Blake, finishing only .01 seconds behind. Spearmon crossed the finish line third at the Beijing Games, but was later disqualified for stepping out of his lane.
