Interesting Itzulia-route this year actually, because you well have a big fight between the 'pure' climbers (Landa, Quintana, Uran, Teuns, Bardet, maybe Latour), the guys with allround capacities (Izagirre brothers, De La Cruz, Porte) and the GC guys who have to make their mark in the ITT (Roglic, Kwiat) to have a chance for the overall victory. 
I like it, because it will create a different racing dynamic and approach. Especially if you compare it to earlier editions, where the climbers were heavily in favor.
