About This Race
The 77K presents the most demanding single-day challenge at Trail Verbier St-Bernard, pushing runners through extended high-altitude terrain that tests both mountain running skills and endurance pacing strategies. This distance attracts experienced ultra runners seeking a substantial alpine challenge without committing to the multi-day demands of the 140K X-Alpine, requiring careful energy management across technical ascents and descents that span nearly the full breadth of the course's most challenging sections. The 77K serves as both a stepping stone for runners progressing toward longer UTMB World Series distances and a destination race for those who prefer their mountain ultras contained within a single, intense day of alpine running.
