PTL

With its unique concept and its specific features, the PTL sets apart from other races. The spirit of the PTL is based on mental commitment, team spirit and adventure, as well as on sporting and mountain values.

This ultra endurance race takes participants on a grand tour of the Mont-Blanc (300km and 25000m of D+), covering high altitude trails, without any way-marking, which requires a sense of orientation on and off the trails. The course changes every year and allows for runners to discover the rich diversity of the French, Italian and Swiss trails of the Mont Blanc massif.

The 2026 course - winding through the ever-present Mont-Blanc and its prestigious satellites - is again this year innovative and out of the ordinary. You will cross little-known places, often difficult to access and offering breathtaking views.

The PTL is run in teams of 2 or 3 athletes, without any official ranking. The teams progress in a rough and demanding mountain environment requiring a strong technical, physical and mental level. Because it is a very difficult and demanding race, applicants go through a selection process requiring the presentation of a file proving their mountain experience.
