L'Antre 2 boucles : 64 km – 3,200 m ascent / 3,200 m descent The main race!

This is the flagship race of this first edition of the Chartreuse Three Breweries Trail. Starting from L’Antre 2 Bières in Saint-Laurent-du-Pont, there’s a 10-bornes warm-up along the Guiers before the real challenge begins, taking you to La Noisigotte in Saint-Pierre-d’Entremont. You’ll then head towards Saint-Pierre-de-Chartreuse, passing by La Marmotte Masquée. The final stretch takes you up to the legendary heights of the massif, climbing towards the Grande Chartreuse monastery and tackling the technical section at the Pas du Loup before beginning the long, final descent back to Saint-Laurent-du-Pont.

WHO WON the Chartreuse Terminorum?

40 at the start. 3 days of adventure. 0 finishers. The answer seems obvious. And yet… For over 50 hours, 40 men and women of 8 different nationalities trekked the trails of the Chartreuse without GPS, without signposts and without assistance. They searched for hidden books, spent two nights in the mountains, and battled the heat, sleep deprivation, navigation errors and their own limits. Three runners reached the legendary milestone of the Fun Run: 3 loops 180 km 15,000 m of elevation gain
