I think we need little bit of perspective about Wiggins “poor” descending
Wiggins lost about a minute on that descent yesterday, with Astana taking all sorts of risks to drop him. On the flat both Astana AND Garmin were going full bore to try and keep the gap, but Sky just rode straight up to them.
Wiggins looked quite comfortable at the foot of the last climb and it was hesjedal that went out the back.
Result was that Garmin shot themselves in the foot, Nibali hasn’t gained any time when racing to his strengths and Wiggins is being written off as a contender.
Not sure how Wiggins can gain time on Nibali without a long TT, but his position is pretty good.
