Sep Vanmarcke has hit the deck three times already in minor crashes. He seems unhurt but it also seems a bit discouraging when there are lots of strong rivals who are not in discomfort. Sometimes I feel like the adrenaline / endorphins from being somewhat injured actually help performance, but not when there is so long to remaining to go. 100 more kilometers of tough stuff. So my guess is that it's not Vanmarcke's day today
Nibali is an enigma, whether he can do anything or not in this context. Not looking great right now. First attempt at the race, and also he is limited somewhat by the relative strength of teammates
