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.


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.

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.
