On a medium mountain stage efforts were high and Team Sky road on the from and literally burnt of the whole field apart from Evans and Nibali. Chris Horner had a flat with about 10km to go but made it back to the peleton where he did some work for the team before calling it a day. I have heard though not confirmed but I would be fairly confident that the figures are correct that Wiggins pushed a NP of 470 watts on the last climb of the day. At 70kg thats 6.7w/kg, 72.5kg its 6.48w/kg and 75kg its 6.26w/kg
