*  Solidarity

Solidarity is a value that is practised and shared by the inhabitants at the heart of natural regions, which can become hostile, and consequently they need to help each other to progress better together or simply to survive. In the name of the principle of solidarity, each player in the field of trail-running is asked to prioritise going to the aid of anybody in danger or difficulty wherever they are and in whatever circumstance.

In a more global manner, the participants and players in the trail-running field often show solidarity by making a commitment in favour of environmental, social or societal causes or by helping the underprivileged. Trail-running race organisers implement this principle of responsibility by directly supporting charitable actions and sustainable development; numerous participants “run for a cause” to support the projects of their choice.

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.
