It doesn't get any tougher than this. Two HC climbs and two first category climbs in the Pyrenees. If Evans, Nibali, and Van den Broeck don't take time out of Wiggins tomorrow, they probably never will. This is Basque country, home territory for the Euskatel team, which will surely go on the attack. However, I don't see a breakaway surviving to the end of this stage. This is one where the GC contenders will likely go mano-a-mano for the victory.
