Road cycling

The climb to the Great St. Bernard Pass (2469 m) from Aosta follows the historic State Road 27 via Gignod. It is a very long climb, about 33 km, which exceeds almost 1900 meters of altitude difference. The gradient is generally constant, with an average of around 5.7%, making it challenging especially for the length and altitude reached. The pass is located on the border with Switzerland.

Road cycling

The climb via the SS27 is good for descending, for climbing the variant that passes through Rosain to Etroubles with little traffic is better, it is a few km longer than the more well-known route, but you never face excessively steep gradients, and on some flat and downhill sections you can catch your breath.
Traffic from Etroubles to the tunnel entrance (beware of heavy vehicles), then the situation normalizes.
From Saint Rhémy onwards, possible very annoying headwind
