Official event pageWhat this race demands
Wildstrubel by UTMB demands sustained endurance over a 110-kilometer trail running journey through the alpine terrain of Crans-Montana, Switzerland.
Ultra-Distance Endurance
Covering 110 kilometers in a mountain environment requires immense aerobic capacity, efficient pacing, and the ability to sustain forward motion over many hours.
Alpine Trail Durability
Navigating the technical terrain of the northern Swiss Alps and the Wildstrubel massif places high eccentric loading on the lower limbs and demands robust structural resilience.
Given the duration of a 110-kilometer ultra-marathon, athletes should target an intake of 60 to 90 grams of carbohydrates per hour to maintain energy availability.
