Ultra Montée de la Berra (UMB) 2026

The Ultra Montée de la Berra is a vertical trail race held in Treyvaux, Canton of Fribourg, Switzerland, typically in late September. Participants select one of four mountain routes: 3.4 km, 6.9 km, 10.3 km, or 17.2 km. The event emphasizes elevation gain over measured distance. The shortest race ascends 695 metres. The 6.9 km route gains 1,390 metres. The 10.3 km course includes 3,400 metres of ascent and 500 metres of descent. The 17.2 km route climbs 3,475 metres and is the most frequently chosen option. Categorized as vertical, nature, and mountain trail, the organizer's French tagline, “Ça va être aberrant,” conveys the challenging uphill nature of the race southwest of Fribourg.
