Sky open up to prove Froome is ‘clean’

Team Sky principal Dave Brailsford has written to the World Anti-Doping Agency (WADA) offering to open the books on Chris Froome to prove the Tour de France leader is riding clean.

Froome has faced almost daily questioning on the matter since taking the yellow jersey almost two weeks ago with victory on stage eight in Ax 3 Domaines, and he started yesterday’s stage 18 to Alpe d’Huez hours after L’Equipe had published an analysis of data Sky had released to them to make their case.

Although Brailsford has long maintained he would not make the team’s power data — numbers which show riders’ output on the bike — public, he did allow L’Equipe access to results from 18 climbs tackled by Froome since the 2011 Vuelta a Espana, as well as various other pieces of biological information.
