Like i said on the first page, he's a fighter. They will not easily "drop" him and be able to call it a day. If Algarve, Burgos, Tour de l'Ain etc have taught us anything, it is that he can sustain his pace and doesn't really crack. I think he will gradually lose time in the real mountain stages. A minute in one stage, 40 seconds in another etc. I agree it's unlikely he will win, but he could still finish top5, which would still be a huge result for him.
This ^^
I don't think he'll explode because he always rides the mountains at his own pace. He will loose some time in several stages, but should be able to finish the race inside the top 10 or even top 5.
