About This Race

The 43K represents the technical middle ground at Trail Verbier St-Bernard, offering experienced trail runners a substantial alpine challenge without the extreme commitment of the longer ultra distances. This distance provides the full mountain experience across varied Swiss alpine terrain while remaining accessible to runners stepping up from shorter mountain races or those seeking a demanding yet manageable day in the Valais Alps. The course delivers significant elevation gain and technical trail conditions that demand solid mountain running experience, making it ideal for runners comfortable with sustained climbing and technical descents over moderate ultra distance.
