I think Quintana did what he could today. I just didn't like when he stopped attacking when Porte/Poels followed him but Froome was not able to. He wasn't racing with Porte/Poels so he should just have continued with his attack.
He will definitely win Tour de France in next few years.
Re:
I thought that Quintana left it too late also but to be honest Quintana managed to gain 32 seconds during last 5 kilometers on not so steep section of climb. I wonder what might happen when they are climbing on steeper sections that are at least 9-10%.
Re: Re:
Froome looks strong right now but I'm not sure if as strong as in 2013. He didn't beat TJVG with huge margins either on Dauphine and maybe is little bit too active on 1st week in my opinion.
I also think that on Wednesday Froome will lose some time to other GC riders.
