The Tor des Géants: a test of ultra endurance
First established in 2010, the Tor des Géants, part of the TORX® endurance series, is a non-stop, 205-mile ultra trail race in Italy’s Aosta Valley. The Tor de Géants route crosses 34 municipalities, 25 mountain passes, and two natural parks, all while requiring runners to pace themselves and manage effort, rest, and sleep over multiple days.
The race takes place in September, with the 2026 Tour des Géants scheduled for September 13th-19th and the awards ceremony to be held on September 20th.
The Tor des Géants route
The TORX® Tour des Géants course starts and ends in Courmayeur, forming a counter-clockwise loop around the Aosta Valley, encompassing technical singletrack, rocky traverses, and long alpine climbs. Stretches through Gran Paradiso National Park and Mont Avic Regional Park impact pacing, with terrain shifting between forests, exposed ridgelines, and runnable valleys that give way to slower technical ascents.
With 78,700 feet of total elevation gain, participants climb the equivalent of Mt. Everest nearly three times during the Tor des Géants’ 330-km distance. Aid stations in mountain towns and villages like Valgrisenche provide opportunities for nutrition and rest, but runners decide themselves how long to spend refueling and recharging.
205 miles of mountainous terrain: the TOR330 race
The Tor des Géants’ distance and lack of compulsory stages make it the world’s longest non-stop trail race, with runners spending up to six days on the course. Climbs exceeding 1,000 meters can take hours, calling for steady pacing and effort management to avoid early fatigue. Descents are equally demanding, with technical terrain requiring precise foot placement.
Runners must determine how often and how long to sleep; most accumulate only a few hours of rest, often in short intervals at aid stations. Sleep deprivation impacts coordination and decision-making, adding to the challenge. Continuing through the night also means making adjustments to stay safe on the trails after dark when decreased visibility and lower temperatures can undermine performance.
Altitude ranges from about 1,000 to nearly 11,000 feet, where lower oxygen levels affect cardiovascular efficiency and recovery. The cumulative effect of distance, elevation, and lack of sleep makes this TORX® race a true test of physical resilience and mental strength on the trails.
The TORX® eXperience endurance trail series
The Tor des Géants is part of the broader TORX® eXperience, which includes multiple events:
- TOR450 Tor des Glaciers: 450 km (280 miles) of glacial terrain
- TOR130 Tot Dret: 130 km (81 miles) on largely the same terrain as the second half of the Tor des Géants
- TOR100 Cervino-Monte Bianco: 100 km (62 miles) linking the Matterhorn and Mont-Blanc
- TOR30 Passage au Malatrà: 30 km (18.6 miles) following the end of the Tor des Géants route
With various lengths and difficulties to choose from, the TORX® eXperience draws skilled trail runners from all over the world.
Running Tor des Géants: endurance for days
In order to prepare for an ultra trail race like the Tor des Géants, you need to train with considerable distances, spending over 10 or 15 hours in the mountains. A typical trail run doesn’t often simulate the duration or elevation of the Tor des Géants. Altitude-specific training is therefore critical, and sustained climbs make cardiovascular intervals and endurance training equally vital.
Performance and comfort also depend on the trail running gear you choose. Trail running footwear for alpine races needs reliable grip and adequate cushioning for hours-long efforts. Runners are required to carry all their own equipment — including water and food — so packs must economize space for sustenance between aid stations. Layering systems are also essential to trail running clothing, as temperatures can shift drastically.

Tor des Géants: registration and participation
Participation is limited to a maximum of 1,100 runners. If the number of pre-registrations exceeds available spots, participants are then selected through a lottery with certain quotas enforced based on a runner’s country of origin.
TOR330 race history and records
Due to its difficulty, the Tor des Géants has a finish rate of only 60%, so just making it to the end is a major accomplishment. Franco Collé has managed this feat several times, and his personal record of 66 hours and 39 minutes is one of the fastest times in the race’s history. In 2024, François D’Haene became the second Frenchman to win the Tor des Géants, marking a dramatic return to competition after two years of injury and setbacks.
In the women’s field, Silvia Trigueros Garrote has been one of the race’s most frequent participants, often finishing in first or second. Katharina Hartmuth holds the current record at 79 hours and 10 minutes.
What to know before taking on the Tor des Géants
The Tor des Géants’ extreme duration taxes your mind just as much as your body. Those eager to rise to the challenge should consider what it will take to make the attempt.
Do you have to qualify for the TOR330?
There is no qualification required for the Tor des Géants, but prior experience with mountain ultras of over 100K and with significant elevation gain is highly recommended. Runners must also provide a valid competitive sports medical certificate.
What is the cut-off time for the Tor des Géants?
The official cut-off time is 150 hours. Intermediate cut-offs at key checkpoints ensure runners are moving at an adequate pace.
How hard is the Tor des Géants?
This is one of the most demanding ultra trail races in the world. Distance and elevation gain both play a role, but perhaps the greatest challenge is the need to self-regulate pacing and make strategic decisions about how and when to recover.
The Tor des Géants: 205 miles of discipline and drive
As the longest non-stop ultra trail race in the world, the Tor des Géants’ combination of distance and elevation is paired with a lack of formal stages to create a structure where runners must balance pacing and recovery over several days, often with very little sleep. Those who make it through the entire Aosta Valley and back to the finish owe their success to a mix of self-discipline, solid training foundations, and a true passion for trail running.
