Tour de France champion Chris Froome says that he is determined to defend his title next July to prove that cycling has entered a new, drugs-free age.
On his way to winning the yellow jersey this year, Froome had to defend himself against suspicions his performance was artificially enhanced – just as Sky team mate Sir Bradley Wiggins had to do 12 months earlier when he became the first British rider to win the race.
