The longest single-stage mountain ultra in the world, the Tor des Géants circles the entire Valle d'Aosta region through more than 25 mountain passes above 2,500 meters. With 24,000 meters of elevation gain and a 150-hour time limit, it is as much a test of sleep management and mental fortitude as physical endurance. The race attracts a passionate international field drawn to its legendary difficulty and Alpine grandeur.

Col Malatra (2,928m)

One of the most feared passes on the course, Col Malatra is often shrouded in cloud and exposed to fierce winds. In 2015, ice on this col forced race organizers to halt the event. Runners scramble over rocky terrain with fixed ropes on the steepest sections.

Rifugio Coda Life Base

At roughly the halfway point, runners pass through a series of refugios that serve as life bases where sleep, hot food, and medical checks are available. Managing rest stops at these refugios is critical to finishing within the 150-hour cutoff.
