If, for some reason, Katusha/Movistar/Sky fail to drive the pace really hard the first time up the climb (though I can't imagine why they wouldn't), it might be an opportunity for one of the top-descending classics guys (say Evans, Gilbert, or even Canc?) to hang on, attack near the top of that first climb, get a bigger gap on the descent, and then hold on 'till the top of the second ascent.
Probably not, but just wanted to imagine an possible alternate scenario to the top 4 sprinting with 2k to go
