The top finishers from stages 1,4, and some of 5 are the pool of contenders.
Maybe Thor will want the Jersey for another day? If he held on two days ago, he can handle this, I think. For that reason I'm ruling out a breakaway finish.
EBH impressed me with his acceleration today, Gilbert can always live up to expectations, Feillu, Rojas, and a few I'm forgetting others should not be ruled out. Evans and Vino types will probably be opportunistic on these rolling courses.
I think Rojas will handle the strong attempts of the leaders to make a small selection, pass a fading attacker in the last 100, and get the good one that he's been close to.
