Welcome to the Tour du Mont Blanc, the most iconic long-distance trail in the Alps - a complete loop around the highest mountain in western Europe, crossing three countries, ten mountain passes and some of the most spectacular alpine scenery in the world. Join us for 6 nights of trail running covering the full route end-to-end, sleeping in traditional mountain refuges along the way, starting and finishing in Les Houches at the foot of the Mont Blanc massif. We'll run six big days, covering roughly 165km, with around 10,000m of total climbing - from rolling alpine pasture and ancient drove roads on the French side, over the Col de la Seigne into Italy and the granite spires of the south face of Mont Blanc, then across the Grand Col Ferret into Switzerland's quieter pastoral valleys, before tackling the spectacular Fenêtre d'Arpette and returning to the French side for the final balcony traverse home. Stops in Courmayeur for proper Italian pizza and in chocolate-box Swiss villages along the way punctuate the bigger days, with plenty of opportunities for coffee, cold drinks and photos en route. This is not a race, it's trail running as a journey.

We'll run as a group at a relaxed, social pace, with the climbs tackled at whatever speed suits the day. Refuges are basic but characterful - communal dorms, simple hot meals, and unforgettable views from the doorstep. Evenings are spent sharing tables with hikers and runners from around the world, stargazing from high alpine balconies, and turning in early for the next day's climb. Please note: the TMB involves significant elevation, exposure and consecutive big days, so a solid base of trail and hiking fitness will help you get the most out of this Run Weekends.
