Who's going to win it today? Wiggins? Cancellera? Kloden? Armstrong? Contador? Possibly rain, and a bit of wind. Wiggins may be tired from yesterday, I would have said Cancellera, but he rode early, so the others will have him to shoot at. Depends whether the weather gets better or worse. It would be nice to see Contador, but this is not his specialty. SPOILER BELOW..
Wiggins will be highly motivated to do well today since it's do or die for him. Unless he can recoup some serious time today, he's pretty much done. I think Lance will hold his own. Wiggins will probably beat him in the TT, but I doubt he'll take enough time out of Lance to beat him in GC. This isn't where Contador shines, but he'd really have to screw up bad to loose the yellow jersey. Cancellara is off the radar.
