I go back to the fear I have already expressed. Gramartboden is an incredibly hard climb, a true and proper murito. It's unlikely we'll get many attack before it; I mean, sure, those 3km will be an attritional spectacle, but I reckon it'll be like a Xorret del Cati finish, just after a lot of climbing and kilometres. The only real hope I have of it not being 15-30 riders slogging it up 15% gradients is the little flat between the two climbs, but attacking from a largish group on Igls would be tricky considering it's shallow. An attack on the downhill is possible, though. Reverse the order of the two climbs and it would be much better I reckon.
But maybe I'm just pessimistic.
(You may have guessed I don't find races decided on >10% that good)
