The Trail Verbier St-Bernard by UTMB X-Alpine is a 140.3km alpine ultra with around 9,127m of elevation gain through the Valais, starting and finishing in Verbier. The overall cutoff is 41 hours 30 minutes, and the highest point is Cabane d'Orny at 2,818m. Winning times are typically around 19–20 hours.
X-Alpine links high cols and hut approaches around the Grand-Saint-Bernard sector with long valley descents into Sembrancher, La Fouly, and Bourg-St-Pierre. Bourg-St-Pierre is a key crew and drop-bag hub mid-race. Expect true alpine weather, snow patches early or late season, and sustained power-hiking grades. Intermediate cutoffs may publish closer to race week - use the overall 41h30 as the planning ceiling until then.
Data is approximate and courses change between editions - always verify against the official race guide.
