Reading the route
OCC links Switzerland to France on the shortest of the Mont-Blanc massif's point-to-point routes, with a dense run of cols and alpine pastures. It starts from Orsières at 8:15 am.
The trail first passes Champex-Lac, then Plan de l'Au, before dropping toward the Trient valley.
From Trient, it climbs up to Tête de Balme, the high point of the route, at 2,292 m.
It then drops via Col des Posettes, passes Le Tour and Argentière, before reaching Chamonix. Runners have fourteen and a half hours from start to finish.
