*  Respect for

The practice of trail-running can entail risks and the search for performance and/or pleasure on no account justifies the distortion of one’s, more or less long term, good health.

Each runner will be particularly vigilant so as not to take any doping product and not to resort to the abusive use of self-medication. They must take care not to exceed their limits to the point of affecting their physical or moral integrity.
