Arrival: Courmayeur Parco del Bollino – Mont Blanc Trail Fest Village

The route, approximately 100 km long with an elevation gain of about 7,400 metres, winds along the spectacular mountain trails connecting Courmayeur, Pré-Saint-Didier, and La Thuile, crossing the stunning Val Veny and Val Ferret, at the foot of Mont Blanc.

The entire course is marked with red flags, signs, and arrows to ensure clear and safe navigation for all participants.

The start takes place in Piazza Abbé Henry, in the historic centre of Courmayeur (1,224 m a.s.l.). After passing through Dolonne and the Fonti Vittoria, the trail climbs towards Champex, Pré-Saint-Didier. From there, skirting the local swimming pool, it continues past the old quarries to reach the charming village of Arpy, where runners will find the first refreshment point at the hostel.

The ascent to the Colle della Croce leads to a scenic section heading towards the Rifugio Deffeyes (2,500 m a.s.l.), before which a very short section equipped with chains is encountered. A refreshment point awaits runners at the refuge. From there begins the long descent to La Thuile, passing the Rutor’s waterfalls and reaching Arly (1,450 m a.s.l.), roughly one third of the route.

Retracing part of the legendary Tor des Géants®, the course reaches the Youlaz Valley (refreshment point at 2,047 m a.s.l.), then climbs over the panoramic Colle dell’Arp (2,572 m a.s.l.), Colle di Youlaz (2,661 m a.s.l.) and the highest point of the race, just below Mont Nix (2,830 m a.s.l.).

A long traverse leads to Col du Berrio Blanc (2,818 m a.s.l.) and Mont Fortin (2,755 m a.s.l.), where an airlifted mobile bivouac serves as a refreshment point.

The descent continues past beautiful alpine lakes, towards Col Chavanne (2,598 m a.s.l.), Col de la Seigne (2,510 m a.s.l.), and the Casermette (2,290 m a.s.l.), reaching the Lago Combal refreshment point (1,952 m a.s.l.).

Following the Tour du Mont Blanc trail, the route climbs to Arp Vieille (2,303 m a.s.l.), passes Lago Checrouit (2,151 m a.s.l.), and reaches Rifugio Maison Vieille (1,952 m a.s.l.), where another refreshment awaits.

After reaching the entrance to Val Veny and crossing the sandy area, the ascent begins towards the Pavillon du Mont Fréty, which hosts the life base at the mid-station of the Skyway Monte Bianco cable car. An old trail then descends to La Palud; after crossing the bridge, the route continues along the panoramic balcony of Val Ferret.

The majestic Val Ferret guides runners to the Rifugio Bonatti refreshment point and into the Malatrà Valley, roughly halfway through the race.

From there, the final two passes, Entre deux Sauts (2,524 m a.s.l.) and Col Sapin (2,435 m a.s.l.), lead into the last descent towards Curru, La Suche, and L’Ermitage.

The triumphant finish line awaits in Courmayeur, at the Parco del Bollino, the vibrant heart of the Mont Blanc Trail Fest Village.
