The PTL® (Petite Trotte à Léon) is one of the UTMB® week races.
Its concept is unique and its specific features set it 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 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 motivational letter and a file proving their mountain experience.

The 14th edition of the PTL® will start on Monday, August 22, 2022 at 8:00 am, at Place Triangle de l'Amitié in Chamonix. The finishes will have until Sunday August 28 at 16:30 to complete the loop and get back to Place Triangle de l'Amitié, for a maximum racing time of 152h30.

The 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.
