David Rudisha - Kenya

   Sport: 800m

 

David Rudisha from Kenya

World champion and world record holder, David Rudisha has dominated the 800m for the past two years. In August 2010, he broke the world record twice inside a week and then took gold at last year's World Championships in South Korea. And the lanky Kenyan is the red-hot favourite to add the Olympic title to his collection. London 2012 will be his first Olympic experience - he missed out on Beijing through injury. His father, Daniel, won silver in Mexico City in 1968.
