I'm currently in the Alpes Maritimes. We did Col des Champs, Col d'Allos and Col de la Cayolle yesterday. 115 km and 3200 m of climbing. The climbs are maybe slightly less famous than those in the Dauphiné and haute savoie, but regarding scenery this is certainly one of the great rides of the Alps. I can thoroughly recommend it. Caracteristics are maybe a bit similar to the great Tour de Suisse stage with Nufenepass, Furkapass and Gotthardpass this year.
We started with Champs from the east, which is the toughest climb of the three, at least rgarding the sides we tackled them from. The avg. gradient seems pretty low with 6.2 % but there are a few descents, so effectively you're mostly climbing at 8% or more. Allos from south is really gentle, except for the last 6 km or so it's basically a long valley ride. The upper switchbacks are spectacular though. The descent is quite infamous, super technical and in terrible condition, not as bad as the one from Champs though. Cayolle from the North is amazingly beautiful and very diverse. Spectacular canyon at the bottom, and high mountain scenery at the top. I can really only recommend it!
We're gonna tackle Turini tomorrow, so let's see how that goes.
