About This Race
The 101K represents the event's premier endurance challenge below the full 250K distance, requiring runners to navigate multiple demanding alpine sections while maintaining steady pacing through technical terrain and significant elevation changes. This distance attracts experienced ultra runners seeking a substantial test without committing to the full ultra-distance, demanding both mountain running skills and the mental fortitude to sustain effort through changing alpine conditions over 12-15 hours. The course provides enough distance to experience the full character of the Eiger region's trails while remaining accessible to runners with solid ultra experience but perhaps limited exposure to extended mountain running.
