About Marathon du Mont Blanc

With the sheer white heights of the Mont Blanc massif as its sensational backdrop, the Chamonix Valley shows the Alps at their most dramatic. First ‘discovered’ as a tourist destination by Brits William Windham and Richard Pococke in 1741, it has become a wintertime playground of epic proportions, more than satisfying the most demanding skiers as well as the après-ski revellers who pack themselves into its boot-stompin’ bars. In summer, lift-accessible highland trails offer thrilling panoramas to hikers, mountain bikers and other high-altitude thrill seekers. With that being said, the Mont Blanc 80km is the place to be.

The Mont-Blanc 80KM race has become legendary in the Chamonix Mont-Blanc Valley. With its 82km and 6000 meters of vertical, it has been recognized as one of the most technical trail races in France. The 80KM race is difficult but it is also one of the most beautiful!

Overview

The Mont-Blanc 80KM race has become legendary in the Chamonix Mont-Blanc Valley. With its 82km and 6000 meters of vertical, it has been recognized as one of the most technical trail races in France. The 80KM race is difficult but it is also one of the most beautiful!

Mont-Blanc 80KM: 82km, 6000m vertical

The course for the Mont-Blanc 80km race has taken a more remote and technical route. The first part of the course starts with a climb up to Bel Achat and then to Brevent (9.5km - 2461m) followed by a traverse at Flegere and the Col des Montets by passing through Tete aux Vents before descending to the Buet (25.9km - 1338m).

For the second part of the course things get serious with a climb to the col de la Terrasse (33.8km - 2645m) passing through la Loriaz: the climb is more technical than by the Tre les Eaux (2013 and 2014), but not as long. At this culmination point of the course, runners descend the combe de la Veudale to join the Emosson dam and traverse toward la Chapelle (38.7km 1963m). (Full aid-station).
From this point there is a sublime view of the Mont-Blanc range and the Tour basin before starting the descent to the villages of Gietroz and Chatelard to then go back up to the hamlet of Jeurs (45.5km - 1778m). The course then joins the Catogne hut and the tete de l'Arolette and the tete de Balme.

Runners will take the Ardoisieres trail leaving from the col des Posettes (51.1km - 1999m) to rejoin the village of Le Tour. They will take the northern balcony trail to climb toward the Planet village before going down via the Rambles trail, which avoids Argentiere, before going toward les Bois.

The third part of the course between les Bois and Chamonix will be a little easier before the last difficulty: the climb up to Montenvers (70.5km - 1900m) passing through one of Chamonix's most well-known tourist sites, the Mer de Glace. One final balcony trail at the foot of the Aiguilles des Grandes Charmoz, followed by the Blaitiere and the Fou lead runners to the Plan d'Aiguille hut (75.7km -2178m) overhanging the Arve Valley.
1150 vertical meters below the finish line awaits runners with open arms after their technical alpine trek of 82km.

The course runners dream of! The trails cross through an entire valley, over summits, south side trails, then the north side trails, allowing them to discover the panorama of the Mont-Blanc range and the magnificent grandeur of the Aiguilles Rouges....a unique spectacle!
