The TLCB invites you to discover the wild side of Chamrousse, far from the ski lifts and close to the summits.
At 1650 metres above sea level, the air is purer, the trails more technical, and the scenery… you'll see for yourself 😏
What you'll find on site:
Course focus:
Here, you don't just run: you explore the other side of Chamrousse, on the Belledonne side, where the trails aren't there to look pretty. It's technical, rocky, pure Isérois terrain. You'll climb, push again, manage your footing... and feast your eyes on the views.
The route takes you through a protected environment, between alpine meadows, open ridges and high-altitude lakes. A raw, preserved little corner of nature, typical of the massif. At every bend, you come across a piece of Isère that few people truly know — except those who love getting lost (and sweating) up there.
