Col de Chaussy

Highlight • Mountain Pass

"No up and straight back down the pass," a small plateau of the Col de Chaussy.
If you ride the shoelace, you'll also get over the pass; it's a nice ride.

Gravel between Lac du Loup and (almost) Col de la Madeleine.

By fair means (understand “I pushed” - almost 1km)

The track through the resort isn't crazy (public works atmosphere), but otherwise, all the rest of the Lacets de Montvernier, Col du Chaussy, Lac du Loup, Col de la Madeleine, and also the descent - great!

Narrow and dizzying road, the credit goes to its builders, who attacked the cliff for real. Its very impressive appearance is reminiscent of the climb to "La Croix de Toulouse", located above Briançon, which is …

Third "effort" (and what effort!), this hill overlooking the ski resort of St. Francois-Longchamp. A hard and long climb, where I went a couple of times in crisis, both for the tiredness accumulated in recent days, and for the heat, today truly remarkable and not even mitigated by shaded areas, given that a large part of the climb takes place …
