About This Race

The 42K strikes the perfect balance for runners seeking a substantial mountain challenge without the ultra-endurance demands of the longer distances. This marathon-length course allows runners to experience the full character of the Wildstrubel terrain while maintaining a more manageable pacing strategy, making it ideal for those transitioning from road marathons to technical Alpine running or experienced trail runners wanting a demanding but achievable mountain objective. The distance provides enough time to settle into the rhythm of technical descents and sustained climbs while still demanding respect for the semi-autonomous navigation and weather management skills that define UTMB World Series events.
