Bradley Wiggins has thanked his Team Sky team-mate Mark Cavendish for helping him keep the lead at the Tour de France.
Wiggins still has the yellow jersey with five stages left and he says Cavendish has been vital in helping him stay in front.
Wiggins has a two minute 5 seconds lead over his team-mate and compatriot Chris Froome.
Tomorrow Team Sky will try to help Wiggins through the brutal stage 16 which has four huge Pyrenean mountains to negotiate.
