What's new in 2027

Verbier Marathon X-Treme – 43 km / 3,000 m+

The current Verbier Marathon becomes the Verbier Marathon X-Treme. Its iconic passage over the summit of Mont Rogneux, at 3,084 m, remains part of the course. Technical and alpine, this route is designed for runners who already have experience on this type of terrain. Participation will be limited to 800 runners.

Verbier Marathon – 47 km / 2,900 m+

A new Verbier Marathon will bypass Mont Rogneux from Col de Mille via Cabane Brunet. Slightly longer but less technical, this new route offers a more accessible option for runners looking to discover the 50K format. Participation will be limited to 1,100 runners.

Both races will start on Friday, July 9 from Moay (Bruson) before splitting at Cabane de Mille.

Route modification at the Gd St-Bernard

Following the delays encountered during the 2026 edition shortly before the Col du Grand-St-Bernard, due to a technical section, the X-Traversée course route will be revised in this area. The X-Alpine will keep the same route.
