From the Col de Légal, this route allows you to make a varied loop with, on its first part, an itinerary in line of crest, before running down to Mandailles Saint Julien. You will go back to The Col de Legal by a route offering a more rural and agricultural framework.
Warning: this itinerary is difficult because of its length and the repetition of technical areas (but not exposed). It is reserved for experienced trail-runners.
