Not sure what your source is but Froome and Bardet were on Alpe D'Huez at the same time! That must mean that Bardet gets second place?

(Also: I'm not sure that reconning Alpe D'Huez is a competitive advantage. Maybe if you're looking to bring Bernal and he's never done it, but they climb that thing every other year. Sometimes twice!)
