Occupation: Olympic-champion track star
At the 2008 Beijing Olympics, Bolt ran a record 9.69 in the 100 m, even while slowing down at the finish. In the 2009 Worlds, he clocked a 9.58 another 100-m record. What does the world's fastest man have in store for the London Olympics? Fellow Jamaican Yohan Blake, who won the 100 m at the 2011 Worlds after Bolt was disqualified because of a false start, has emerged as a worthy rival. Still, as long as Bolt is lined up, he'll always be the man to beat.
