You’ll be exploring the unspoilt, wild landscapes of Les Cerces, in a unique high-mountain setting, amongst the ibex and chamois that call this place home. Four technical and challenging routes are on offer.
Four technical and challenging routes are on offer:
• the Grand Tour des Cerces (60 km – 4,000 m elevation gain): an exceptional route, the longest and most demanding.
• The Marathon des Cerces (45 km – 3,200 m elevation gain): a majestic route with a distinctly alpine profile.
• The Petit Tour des Cerces (26 km – 1,850 m elevation gain): ‘petit’ (small) is the only thing about it; its highest point at 2,717 m and the technical nature of the trails make it a challenging event
• The Tour des Chapelles (12 km – 600 m elevation gain): a magnificent route that remains demanding despite its 12 km length. You’ll alternate between wide tracks and long single tracks.
