Bk trail - Ossès 2026

BK Trail is a late-July trail race held in Bidarray, a Basque village in the Pyrénées-Atlantiques of southwest France. It features two mountain distances: a 24 km route with approximately 1,700 metres of elevation gain and a 45 km route with about 2,700 metres of elevation gain. The race takes place on the GR 10, near the Iparla ridges. The routes consist of genuine mountain trails, not road-style runs with some unpaved sections. Participants are drawn to the steep ascents, forest paths, open mountain landscapes, and the authentic Basque-country trail character of an event based in Bidarray, distinct from a large urban race.
