The overall Tour de France leader Chris Froome has had to defend himself against critics who believe he could be following in the footsteps of the shamed drugs cheat Lance Armstrong.
Froome's stunning stage win up Mont Ventoux on the weekend prompted comparisons with the disgraced Armstrong, but the Kenyan-born British rider has claimed since the start of the race that he is "100 percent clean" and he's had enough of being made to feel he is a cheat.
Last year's runner-up says he and his British team-mates have spent months away from home training and sleeping at high altitudes getting ready for the Tour.
Team Sky's principal Dave Brailsford says he's prepared to give the World Anti-Doping Agency all their team training data.
