Urduñako Mendi Lasterketa 2026

The Urduñako Mendi Lasterketa begins and ends in Foru Plaza in Urduña, Bizkaia, leading runners into the Gorobel mountains. Participants can choose from three routes: a 33 km solo trail race, a 33 km relay, and a 14 km popular race. The primary 33 km course ascends 1,750 meters, holds UTMB Index status, and commences in the morning. The extended route crosses forests, ancient beech woods, rivers, and significant waterfalls, featuring numerous ascents and descents across the Sierra Salvada passes. This mountainous region is designated as both a ZEPA and a ZEC, grounding the race in its natural setting rather than a mere marked course. A recent running saw 210 finishers, indicating a dedicated mountain running field without being an overly large event.
