In reply to GrahamD:
Well they didn't need to bother marking anybody in the end (apart from Valverde but that was ultimatley in vain as Quintana couldn't follow either) they just rode away......
I cant remember a GC rider coming in at the end of the first mountain stage with nearly a minute over his nearest rivals for a long time, and all that gained in the last 8k, its pretty much a done deal now, Froome would have to crack spectacularly to lose now, I cant see that happening.
Be a good fight for the minor podium palces though.
