Pendleton defends Froome over 'hurtful' doping questions

Britain's Chris Froome is set to win the 100th Tour de France on Sunday.

However, he has been forced to respond to questions about doping, following revelations over Lance Armstrong and other former Tour de France giants who used drugs in the 90s and 2000s.

Froome told BBC Sport: "I've also believed in people who have turned out to be cheats and liars. But I can assure you, I'm not."

Speaking on The Andrew Marr Show, Olympic gold medallist Victoria Pendleton praised Chris Froome's efforts, calling him an "absolutely phenomenal athlete".
