Media EDP DesafiOSOmiedo 46k 2026

The Media DesafiOSOmiedo (MDS) is one of the event’s signature distances: a wild, spectacular high‑mountain route that demands strength, technique and flawless effort management. Over 46.8 km, the course mixes runnable sections with very tough terrain, accumulating 2,270 m of ascent and an impressive 3,780 m of descent, making it a challenge both physically and mentally. The start in Valle del Lago sets the tone with narrow trails, steep ramps and uneven terrain that forces runners to find rhythm without overspending early. This opening section alternates explosive climbs with faster segments, always surrounded by Somiedo’s characteristic landscape: forest, rock, humidity and pure wilderness. The heart of the race arrives with the major climbs, where most of the positive elevation gain is concentrated. These are long, sustained ascents that require power‑hiking, pacing and a cool head. The terrain becomes more alpine, more exposed and more technical, offering spectacular views that reward the effort. After reaching the high point, the course launches into the most punishing section for the legs: a massive 3,780 m− descent toward Pola de Somiedo. It’s a beautiful but highly technical downhill, with fast stretches, loose rock and constant changes of rhythm. This is where the race is decided: those who arrive strong can fly; those who don’t will suffer every meter. The MDS is ideal for experienced mountain runners who enjoy long, technical routes with big elevation profiles. It’s not a race for improvisation — it requires strength, endurance, terrain reading and a clear strategy. In return, it offers one of the most spectacular courses in northern Spain, ending with a vibrant finish in Pola de Somiedo, where the event atmosphere peaks.
