Quintana does usually seem to go well in the last week when everybody else is tired…
I would say though that was when he was fitter than he seems to be now. He definitely seems to be well down on power compared to other GC contenders like Mollema, Porte and even Yates. I think he knows it as well witnessed by his complete lack of attack on stage 9 to Andorra Arcallis. It was all he could do to follow Froome’s wheel.
Last year Froome admitted he was tired and a bit sick in the last week and he has deliberately modified his training to be stronger right through the Tour. Quintana may well recover somewhat and the windy last few days have been hard on him I think. Next Wednesday will be the real test with a big uphill finish after the rest day.
