The good thing for Sky is the timing of this problem. They now have a flat stage to recover as best they can, followed by a TT where the rest of the riders bar Catweasel can take it a bit easier. The Ventoux stage is perfect for Sky with a long flattish run in followed by one monster climb, but one where their train should be pretty effective. I expect Froome to put another 30 sec - 1 min into the GC boys then. If he TT's well then he should have a lead of 2 1/2 mins to play with after Ventoux. The alps will be a different story now, with long range attacks to be expected. Very interesting tour so far.
