Cycling Col du Chaussy via Lacets de Montvernier
Ride 13.4 kilometers gaining 999 meters at 7.5% average grade.
While the climb itself is a challenge and worth including on your route in the extraordinary Saint Jean de Maurienne Climb Zone, it is the World Class hairpins which make this climb exceptional. This is simply an amazing climbing experience due to its amazing formation of hairpins (lacets in French), 17 in a brief cluster at the start. 0.4 miles up the climb we begin a unique set of compressed hairpins known throughout the world as “Lacets de Montvernier” (or in English, “Shoelaces of Montvernier”) that cover 1.2 miles/1.9 km at 8.7% average grade gaining 540’.
The climb begins just northeast of E70 and D1006 near Pontamafrey, six kilometers north of Saint-Jean-de-Maurienne.
This is a climb that simply must be done if you’re anywhere in or near the Savoie Department of southeastern France and the French Alps climbing hub of Saint-Jean-de-Maurienne.
