Tor des Géants is a 336.5km single-stage ultra-trail with 26,182m of elevation gain, run on the Alte Vie 1 and 2 of the Aosta Valley and starting and finishing in Courmayeur, Italy. The overall cutoff is 150 hours and the highest point is Col Loson at 3,295m. There are no mandatory stages: runners manage their own sleep across six life bases, which is what makes the race unlike any other hundred-miler.
The race starts on a Sunday in two waves, at 10:00 and 12:00, and every time barrier for the second wave falls exactly two hours later than for the first. Six life bases - Valgrisenche, Cogne, Donnas, Gressoney, Valtournenche and Ollomont - carry your TOR bag and are the only points with a bed, a shower and a full drop bag. Expect three to six nights out: the 150-hour limit leaves room for more than six days on the course, and sleep management rather than pace decides most finishes.
Data is approximate and courses change between editions - always verify against the official race guide.
