Well Carapaz lost 45secs in the first TT and two minutes in the 2nd. If he maintains the form of the 2nd, he needs at least a minute but preferably nearer 1.5 minutesRace feels really nicely poised. Carapaz, the best climber of the favourites, needs more time because Roglic will get time back on the TT. He has to attack again and Roglic will have to respond. Landa can follow and go for stages. The loser feels like Nibali who doesn't seem to be able to outclimb Roglic and can't out-TT him either.
Loads of good stages to come so I'll probably be completely wrong
