Sky have suggested the World Anti-Doping Agency be given full access to all their information in order to quell insinuations that their team is doping.
Sky’s team principal, Sir Dave Brailsford, said: “They can have everything we’ve got. They can come and live with us. They can see all of our data, have access to every single training file we’ve got.
“They can then compare that data on a consistent basis. And they could then tell the world whether they think this is credible or not.”
Chris Froome was again forced to field questions about doping a day after tightening his grip on the yellow jersey with a historic Stage 15 win.
“I just think it’s quite sad that we’re sitting here the day after the biggest victory of my life, a historic win, talking about doping,” Froome said.
“My team-mates and I have been away from home for months training together and working our arses off to get here, and here I am accused of being a cheat and a liar.”
These were the first signs of frustration from Froome after days of calmly batting away the questions.
When Lance Armstrong’s name was mentioned atop Mont Ventoux on Sunday, the 28-year-old said he would take it “as a compliment” regarding his performance, but on Monday insisted he was a very different man to the American. “Lance cheated,” he said. “I’m not cheating. End of story.”
Brailsford was equally tired of the topic, and told reporters to come up with a better way of settling the issue than asking the same questions every day.
“Rather than asking us to come up with some way to prove we’re innocent, why don’t you collectively have a meeting and tell me what would prove it to you?” he said. “It’s a rest day, it’s 10am, and the bottom line is I’m defending somebody who’s done nothing wrong.
“I’m more than happy to try to find a way to convince you guys that we’re doing nothing wrong but we need a little bit of help.”
Some have demanded that Sky release their power data - numbers which show the power output of their riders on the bikes - but Brailsford does not want to release the team’s “trade secrets” to rival operations.
