This Giro is over for Wiggins. The plan was very simple:
* take time in the Team Time Trial = check
* take time in the Time Trial = more or less check
* consolidate in the rest of the stages = not check, even lost 1.5 minutes
Where is he going to take time back? Uphill? Downhill? Uh, no.
His contenders know his weak point and will attack him there, Evans - Nibali - Hesjedal - Scarponi - even Gesink of all people will seek there moment. If it rains tomorrow expect a Jan Ullrich from Wiggins.
And, to be frank, the Giro is no Tour. These mountains are way tougher. Also the way the Giro is ridden is totally different.
I would be very surprised if Wiggins would come back in GT contention.
