A finish atop a super-steep ramp with little space at the summit in the middle of nowhere... yet this is not the Vuelta. The stage supposedly has the highest elevation gain of any stage in the race.

Climbs
The opening ramp through Châteaugay is roughly 3k at 6%, I couldn't find a profile, but it should help the stronger climbers if the breakaway forms early. 25 kilometers in, the riders tackle a proper climb, the cat. 1 Col de Ceyssat.
The race heads through the Monts Dore up the cat. 3 Col de Guéry and then reaches the harder climb of Montée de la Stèle.
A long, gradual descent follows this climb, the intermediate sprint is at a flatter section near its end. The terrain remains undulating, but the Côte de l'Estiade and the Côte d'Anglards-de-Salers aren't too hard. With 15k to go, the business end of the stage finally starts, first with the Col de Néronne from its previously unused steepest side...
...then the Pas de Peyrol, also from its steepest side, although this one has been used quite often. It's the final 11.3k of the profile below, a flat and a short descent from the summit of Néronne, then 3.5 easy and 2 brutally steep kilometers to the finish.
