*  Respect for the
environment

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.

Definition of trail-running

Trail-running is a pedestrian race open to all, in a natural environment (mountain, desert, forest, plain…) with minimal possible paved or asphalt road (which should not exceed 20% of the total course).

The terrain can vary (dirt road, forest trail, single track…) and the route must be properly marked (1).

The race is ideally – but not necessarily – in self-sufficiency or semi self-sufficiency (2) and is held in the respect for sporting ethics, loyalty, solidarity and the environment.

Classification of Trail running races

  • Trail: Under 42 km
  • Trail Ultra Medium (M): 42 km to 69 km
  • Trail Ultra Long (L): 70 km to 99 km
  • Trail Ultra XLong (XL): 100 km and more

(1) "Properly marked" means that the runners will receive enough information to complete the race without getting lost. 
That includes physical markings (flags, tapes, signs…) or GR permanent markings or GPS tracks or map indication.

(2) "Self-sufficiency or semi self-sufficiency" means that the runner has to be autonomous between aid stations, regarding clothing, communications, food and drink.
