Going by the link in the first post, the stages in the Alps could look like this, going by the latest info on that page
Digne-Les-Bains - Pra-Loup (MTF)
possible climbs:
- Col des Champs - 2001m (mentioned on Velowire)
- Col de Cayolle - 2326m (would make the most sense by far )
- Pra Loup ~ 1630m MTF
Pretty damn good, if true
rest day
Gap - Saint-Jean-de-Maurienne
probable climbs:
- Glandon from the south
- Col du Chaussy (as per Velowire) - great climb. Finish not too far away from the descent, I guess.
Saint-Jean-de-Maurienne - La Toussuire (MTF)
short(?) mountain stage to showcase the Maurienne area
probable climbs:
- Croix de Fer via Col du Glandon - HC
- La Toussuire 1st
Mollard too, I guess
final mountain stage (Alpe d'Huez?) (MTF)
no new reliable info on this one, it seems. The older rumor was of another double Alpe d'Huez ascent.
