Sky ready to give WADA all data
This year's race has been under extra scrutiny as it is the first Tour being staged after Lance Armstrong admitted that he had cheated his way to seven Tour titles from 1999 to 2005. Although he was stripped of all seven of the titles, the sport is still trying to salvage its image.
With athletics also under a cloud following the positive dope tests of former 100 metres record holder Asafa Powell and 2007 world 100 metres champion Tyson Gay at the weekend, Brailsford was adamant that Froome and other riders in his team are clean and their achievements should not be undermined.
"Given what's happened with Armstrong, given what's happened with athletics I think just replying with the old way of thinking is not going to give us solutions," Brailsford told a packed news conference at his team hotel here on Monday.
On Sunday, Froome, rooted to his saddle, accelerated brutally to leave rival Alberto Contador of Spain stuck on the tar on his way to victory in the 15th stage, triggering a collective gasp in the press room.
The Briton now leads second-placed Bauke Mollema of the Netherlands by 4:14 and Contador by 4:25.
