DesafiOSOmiedo
The EDP DesafiOSOmiedo is one of the most spectacular mountain races in northern Spain. Since 2013, this event traverses the Somiedo Natural Park, a UNESCO Biosphere Reserve and home of the Cantabrian brown bear. Three distances for all levels, starting and finishing in Pola de Somiedo.
The Courses
From Pola de Somiedo, all three courses head into the park’s valleys and summits, passing glacial lakes, traditional mountain huts (brañas), and grazing passes.
- UTDS (70K) — 8,000m D+ covering the full park. Start at 6:00 AM. 14-hour time limit with cutoffs at Saliencia, Farrapona, Valle del Lago and Puerto de Somiedo.
- MDS (46K) — 2,270m D+ through the heart of the park. Start at 8:00 AM. 10h 15min time limit.
- SDS (24K) — 1,038m D+ for those seeking a shorter but still scenic distance. Start at 9:30 AM. 5h 15min time limit.
Terrain and Difficulty
Somiedo Natural Park offers varied terrain: mountain trails, shepherd tracks, high mountain sections and passes through centuries-old brañas. The UTDS is a demanding race with 8,000m of elevation gain that tests both endurance and technique. The MDS and SDS are more accessible but no less spectacular. Check our trail shoe recommendations for mountain terrain.
July Weather in Somiedo
July in Somiedo offers the best conditions of the year: pleasant temperatures in the valleys (18-25°C) and cool at the summits (8-15°C). However, afternoon storms are common in the Asturian mountains. The early UTDS start (6:00 AM) makes the most of the cooler hours. Bring sun protection and a waterproof windbreaker even if the forecast looks clear.
Somiedo and the Brown Bear
Somiedo is one of the last refuges of the Cantabrian brown bear. The natural park protects a unique ecosystem of forests, glacial lakes and brañas (traditional shepherd huts with broom-thatched roofs). Lagos de Saliencia and Valle del Lago are two of the most iconic spots on the course. Beyond the race, Somiedo is worth exploring for its nature and gastronomy. Discover more races in Asturias.
