Grand Raid des 3 Vallées - 110 km 2026

The Grand Raid des 3 Vallées 110 km is a mountain trail ultra based in Val Thorens, French Alps. Its most striking detail is the start: runners depart from Cime Caron at 3,200 meters, then face a 110-kilometer route with 5,880 meters of climbing. The race begins at 16:00, meaning participants will undertake a long alpine effort that includes evening and night running. The 110 km is part of the wider Grand Raid des 3 Vallées program, which includes shorter 10 km, 25 km, 50 km, and 70 km races, plus a 170 km option. There is also a 170 km relay for teams of eight, making the event suitable for both solo ultra runners and groups wishing to share the longest distance. The available facts indicate a high-altitude race centered on Val Thorens, rather than a road-style mountain run: the distance, climb, and Cime Caron start are the primary distinguishing features.
