Beautiful, technical, wild, and demanding—there are many ways to describe the TDS, which connects the Aosta Valley to Savoie, passing through the villages of the Mont Blanc tour and the surrounding mountain ranges. Running through this unique playground means following trails where history and mountain landscapes blend, where technical terrain meets the kindness of its inhabitants.
A 145 km trail with 9176 meters of elevation gain—this is the challenge that runners must take on in this must-do race!
Bourg Saint Maurice is an important stop in this race, featuring the first major refreshment point, located at the gymnasium of the middle school in the town center.
The first participants will arrive around 4:15 AM, with runners passing through until approximately 11:00 AM.
