Let's hope he stays fit and healthy for London 2012, as he tries to reprise his golden performance from the 2007 World Championships.
The second-fastest man in the history of the world, he'll be hoping to bolt (ahem) past his obvious rival and win gold for the US in the 100 metres.

This year's Olympics features some of the fastest men who have ever walked this earth, so the 100 metre final on August 5 could be a cracker.
Gay routinely beats off his athletic competitors and finishes in less than ten seconds, which we're told is a good thing when it comes to sprinting.
Best of luck, Tyson.
