Wildstrubel by UTMB

Wildstrubel by UTMB is a trail-running series in the northern Swiss Alps, centered on the Wildstrubel massif and its high-mountain terrain. The race options range from the Wild 25 to the Wild 110, with longer distances including 42 km, 55 km, 72 km, and 113 km courses. The longest race ascends 6,600 metres, marking it as true mountain running, distinct from road ultras with minor elevation changes. The courses traverse Alpine pastures, glacier regions, and the Oberland mountain range, offering views toward the 4,000-metre peaks of the Valais. Starting points across the series include Crans-Montana, Kandersteg, Adelboden, Lenk, and Leukerbad, contributing to a dispersed Swiss resort atmosphere rather than a centralized race hub. Multiple distances award UTMB Running Stones, from one on the shortest race to four on the Wild 110, attracting runners aiming for UTMB qualification alongside those seeking a challenging Alpine race.
