Regulations 2022


The world of trail running brings together different sorts of people who do not only practise sport, but who also believe in and respect a number of important values that form the ethics of sport.

Respect for People
Self-respect: no cheating, either before or during the run;
Respect for the other runners: always help another runner in difficulty;
Respect for the volunteers: they take part in the race simply for the pleasure of helping out.
Respect for Nature
Respect plants and wildlife: don’t leave rubbish behind.
Stick to the paths marked, without taking shortcuts, in order to prevent soil erosion.
No money prizes
Just a prize to reward each runner who finishes the trail.
Sharing and solidarity
Everyone, be they runners or volunteers, should take action to ensure support is provided in all situations.

Preliminary statement: important note regarding the SARS COV 2 pandemic (COVID 19)

The persistence of the pandemic still makes it difficult to predict the scenarios that will arise during the days of the event. In the coming months, all the measures necessary for the realization of the Gran Trail Courmayeur 2022 will be defined in compliance with the prescriptions that will gradually arrive from the competent national and international authorities. This regulation will be unilaterally updated accordingly. Any substantial changes will be communicated through the 100x100 Trail newsletter, published on the website and on all official race channels.
Gran Trail Courmayeur, GTC100, GTC50, GTC30 are trademarks owned or used exclusively by VDA Trailers. Any communication of the event or use of images of it must be done in observance of the name of the event and registered trademarks, subject to agreement by the organisation.

Any dissemination for commercial purposes of photographic or video images captured during the event, via any means (internet, social networks, TV, press, magazines, etc.), without written authorisation from the organisation is prohibited.


    The Gran Trail Courmayeur is organised by VDA TRAILERS, a limited liability amateur sports association, with the patronage of Courmayeur, Pré-Saint-Didier and La Thuile municipalities.

    Three trail runs through a natural landscape, along Val Veny and Val Ferret with the start and finishing line in the municipality of Courmayeur and going through the municipalities of Pré-Saint-Didier and La Thuile. This is a single – stage race with complete freedom in speed that must be completed within a set time.

    GTC100 :
    Race of about 100km with an altitude range of 7900 mt; it must be completed in 33 hours.

    GTC55 :
    Race of about 55km with an altitude range of 3800 mt; it must be completed in 18 hours.

    GTC30 :
    Race of about 30km with an altitude range of 2000 mt; it must be completed in 8 hours.

    Difficulty level
    HARD: difficult track racing, expert trailers, rugged, exposed and steep terrain, with short stretches equipped but without mountaineering difficulties, prolonged passages an important quote

    ITRA classification
    When it comes to trail racing, there is something for everyone! ITRA categorizes trail races according to their level of difficulty.
    Knowing the difficulty of a trail race allows runners to select the race that best suits their needs as well as to prepare for it to the best of their ability.
    ITRA race evaluation provides runners and organizers with a consistent measure all around the world.
    ITRA uses a validated method to calculate the level of difficulty of a race and this method is based on the notion of ‘Km-effort’.
    The total “Km-effort” of a race are calculated by taking into account both the distance and the elevation gain

    GTC100 ITRA Points 5 Mountain Points 10
    GTC55 ITRA Points 3 Mountain Points 8
    GTC30 ITRA Points 2 Mountain Points 8

    Underestimating the physical and psychological preparation required, as well as the appropriate clothing and equipment, can have dangerous and potentially life-threatening consequences!

    If you are considering taking part, it is therefore imperative:
    • to be totally aware of the unusual length and peculiarities of the race;
    • to be thoroughly prepared, both physically and mentally;
    • to have equipped yourself before the race for total self-reliance in the mountains, so that you can manage any problems involved with this type of endurance trail, in particular:
      • coping alone and in isolation with the physical and psychological problems of extreme fatigue, gastro-intestinal upsets, muscle and joint pain, minor cuts and injuries, etc;
      • managing altitude and weather conditions that could potentially cause extreme difficulty (darkness, high wind, freezing temperatures, fog, rain and snow) without any help;
      • understanding that the organisation is not responsible for helping runners to manage any common issues that might arise and that with races like the Tor des Géants®, across mountain terrain, your safety depends on your own capacity for self-management in extreme situations.

    The race is open to any man or woman over the age of 18 at the time of registration, members or otherwise (categories include Seniors and Veterans). There are no specific restrictions on registering for the Gran Trail Courmayeur, but it is strongly recommended that you have taken part in at least one other long-distance endurance trail over mountain terrain with a significant altitude difference.
