British athlete Dwain Chamber's Olympic preparations... in Chamonix

Britain's Dwain Chambers, before travelling to London next week for the Olympics, has come to Chamonix to complete his physical preparation. The 100 metre sprinter, suspended for doping in 2003, is now finally returning at the highest level. Dwain Chambers will be at the London Olympics, to convince athletes not to take performance drugs. It's easy to spot Mr Chambers: he will be either in the weight training room of the Richard Bozon Sports Centre or on the Chamonix running track nearby.
