Going for gold – American sprinter Tyson Gay says he's in his prime and fit and ready for the London Olympics.
Beating Bolt – Gay will be hoping to repeat his performance at the 2007 IAAF World Athletic Championships in Osaka, Japan where he crossed the line first in the 200m ahead of Usain Bolt.
Jumping for joy – But Gay stormed to gold in the 100m, beating Derrick Atkins of the Bahamas (left) and Jamaica's Asafa Powell in a time of 9.85 seconds.
Three and easy – Gay also won gold as part of the U.S. 4x100m relay team.
Subjected to silver – Two years later in Berlin though, triple Olympic champion Bolt won gold in the 100m and 200m, setting world record times in both. Gay had to settle for silver in the 100m.
Strung out – Prior to the Beijing Olympics, Gay was troubled by a hamstring injury which meant he arrived at the Games in less than perfect shape and he failed to win a medal. Here Gay (far left) finishes fifth in the 100m semifinal to miss out on the final, won by Bolt in record time.
A Greene mentor – Gay counts America's retired sprinter Maurice Greene as both a hero and a mentor. The former Olympic 100m champion's advice and support "really means a lot to me," says Gay.
Near miss – Gay's first outing at the World Championships at Helsinki's Olympic Stadium in 2005 ended without a medal. Here he can be seen (second from left) finishing fourth in the 200m final.
