*  Respect for the

Races take place in fragile natural environments. All players involved with trail-running races, runners, organisers, partners, accompanying persons make a commitment to protect the natural equilibrium.

Organisers of trail-running races must do all they can to reduce the negative impact linked to the running of their races. They make a commitment by sharing information and making efforts to educate in order to contribute to the general awareness of the natural environment’s fragility.
Each organiser will identify the environmental risks engendered by their event and propose concrete actions to reduce the risks to the minimum. They will encourage the use of public transport or car-sharing and limit, as much as they can, the use of other motorised equipment.
Each runner makes a commitment to adopt the most relevant behaviour to minimize his or her impact on the terrain through which he or she passes.

Together, the members of the trail-running community act as ambassadors for the promotion and conservation of natural environments.


If the trail running has won many fans around the world in the early 2000s, this sporting discipline was not yet recognized as such. That's why more than 150 passionate actors gathered in 2012 to lay the foundations of this original practice and affirm its values. 

September 3, 2012: 1st Assises Internationales du Trail

On September 3, 2012, 150 trail running enthusiasts from 18 countries around the world gathered in Courmayeur, Italy. Race organizers, equipment manufacturers, elite athletes, coaches and media shared their experience with the desire to structure and secure their practice. Indeed, the trail running, born in the United States in the late 70s, was still not officially recognized as a sport in its own at the international level.

It was the first time that so many trail running players met. These sessions enabled these participants from all over the world to become aware of the diversity of their points of view and the need for the trail to organize themselves as a discipline in its own right, while taking into account the approaches of all the continents: America, Asia, Africa, Oceania and Europe.
The 1st Assises Internationales du Trail has initiated a concerted dialogue with the aim of:
  • guarantee the health and safety of runners and all those involved in trail running
  • affirm, preserve and defend the values of trail running.

5 working groups to structure the discipline

Since 2014, 50 volunteers from 13 countries on five continents have continued the work initiated during the 1st Assises Internationales du Trail.
5 working groups, composed of race organizers, athletes, coaches, representatives of sports federations, equipment manufacturers and the media have united their cultures and their points of view to accompany this evolving discipline, with the following result:
  • the definition of what trail running is, a definition shared around the world,
  • the drafting of an ethical trail running charter to assert the values of the discipline,
  • the implementation of a health policy to promote a doping-free sport and protect the health of runners,
  • the development of a reasoned management of high level athletes,
  • the elaboration of the rules for a uniform international ranking.

July 2013: The birth of ITRA

The 5 working groups have created the need to create an association bringing together all the trail players around shared values and principles around the world. This is how the International Trail Association (ITRA) saw the day in July 2013, animated by the passion of the trail and the enthusiasm of its 14 founding members.
