Yeah, that was another great stage, that final hill did do exactly what it should have done. And still the Gavia to come! As Scarponi said when the route was announced:
"The Gavia, as well? This is going to be hell! I just can't wait until I can see light at the end of that tunnel on top of the Gavia, literally and metaphorically, because the Tonale's not too hard... But, mamma mia, what a Giro!"
I've changed my mind of Wiggins again - looking at the pictures of him (in the link above) and seeing him today, he seems to have been coasting a little bit. I am guessing that perhaps he is trying to preserve his energy for the final TT.
