What can anyone do to beat Cobo at this point?
Well, I hope Sky at least try and go on the attack rather than just giving in. Chase down any breaks and keep Froome at the front so he at least has a chance of getting some bonus seconds in the sprints/climbs/stage finishes. It's unlikely, but there are still over a minutes worth of bonus seconds up for grabs!
There's no point in attacking unless there's an opportunity to split the peloton in the wind. The remaining hills aren't hard enough to cause much damage (
I've ridden up some of them without too much trouble!) and are all too far from the finish.
Much though I'd love to see a Sky team time trial from 10km out, it wouldn't work.
Just zooming off the front, even as a team, is pointless because most of the field (especially Geox, Rabobank, Leopard-Trek, Liquigas) will chase and catch you because your success would disadvantage their top riders.
And you won't get any help chasing down breaks unless one of the top five in GC are in them.
Like I said, i've thought about this.
