Usain Bolt broke world records in both the 100 and 200-meter dash in Beijing, but it might not be so easy this time around.

In what is arguably the sport's premiere event, Bolt will be in a dogfight with both Jamaicans and Americans in the 100. He lost to Yohan Blake last month in the Jamaican Olympic Trials, and has had some trouble getting out of the blocks. Blake also won at the World Championships last year after Bolt false-started.
The American contingent features legitimate contenders in both Justin Gatlin and Tyson Gay. This could very well end up being the most exciting 10 seconds of the London Olympics.
Bolt considers the 200 to be his main event, yet Blake once again bested him in it at the ultra-competitive Jamaican Olympic Trials. The Jamaicans have a chance for a podium sweep as Jason Young, 21, has gone as low as 19.86 seconds.
