Wildstrubel by UTMB, first run in 2022, is billed as an extraordinary trail race through Switzerland’s northern Alps. Set between the Swiss cantons of Valais and Bern, runners will race in the Wildstrubel massif and Crans-Montana as UTMB continues to expand its stable of events.
Featuring three main races over a four-day programme, organisers are enticing entrants with “perfectly manicured mountain pastures, breathtaking views of the Valais’ 4,000m peaks, and the striking landscapes of the Oberland mountain range”.
