*  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.
