Alberto Contador open to sharing power data

Alberto Contador says he would be willing to follow Team Sky's lead and release his power data but insists the conclusions drawn from such numbers cannot always be believed.

On Tuesday's rest day, Sky's head of athlete performance Tim Kerrison presented data from Froome's climb up the Col du Soudet - the summit finish of stage 10 where he put time into all his rivals - showing he averaged 414w with an average heart rate of 158bpm.

At the Tinkoff-Saxo press conference the same day, Contador said he believes Froome is being questioned too much about the validity of his performances.

“I have no problem providing my data but it’s a question that is variable,” Contador said. “Sometimes people make calculations that are not real when they speak about my performance. I look at my SRM, and the data is very different from what they say.

“About Froome, everybody is questioning him and I think maybe it’s too much because the other day it was very disgusting what happened with a spectator throwing urine on him. I think we have to see an end to this kind of behaviour.”

Contador sits in fifth place in the general classification, nearly four-and-a-half minutes down on Froome, and insists that although his chances of completing the Giro/Tour double are very slim, he won't be taking it easy to Paris.

“I don’t think I will try [the double] again,” he said. “In any case, I still think it’s possible. The Giro was very difficult and tough with Astana strong from the beginning. I arrived at the Tour and the level of my rivals has been very high, so all together the double remains a difficult task.”
