LE MARATRAIL DE L'ECUREUIL : 42 KM - 2300m D+

An open route, a stop at the three partner breweries, and landscapes that are completely different between the first and second halves of the route. That’s what this challenging route promises – though it doesn’t feature any physically extreme sections. You’ll set off from La Noisigotte in Saint-Pierre-d’Entremont, passing through Saint-Pierre-de-Chartreuse and then La Marmotte Masquée. The final stretch then takes you up to the legendary heights of the massif, climbing towards the Grande Chartreuse monastery and tackling the technical section at the Pas du Loup before beginning the final, long descent towards St Laurent du Pont.
