About this race
The Greina Trail events series is centered on the Classic Greina Trail, a 27 km mountain race featuring 1,440 meters of ascent and an equal amount of descent. This is the series' primary race, now in its seventh edition.
The route crosses the Greina plateau, passing through the most distinctive sections of this high mountain region. It is the course most frequently cited by participants as the series’ signature route, offering sufficient ascent, descent, and technical terrain to qualify as a true endurance test, distinct from a simple trail run.
