I think tomorrow is going to go a bit weird. Quintana will not be allowed in the break. That long drop off the l'Iseran is could turn in to a war of the descenders which won't produce much and that comparatively short hack up to Tignes will be the stage of some ineffective tactics. Alaphillipe to lose maybe 30s.
My money would be on Bernal to win what will effectively be a royal rumble on the way up to Val Thorens.
