Urtxin'trail is a night trail race held in Hasparren, Pyrénées-Atlantiques, on the Ursuya mountain. Organized by Hasparren Urtxintxak Athlétisme, it offers two mountain routes: one approximately 14.3 km with 667 m of elevation gain, and another about 23.85 km with 1,212 m of elevation gain.
The race is compact yet steep, with both options featuring significant elevation gain over short distances. The shorter route is suitable for runners seeking a challenging evening trail run without extreme distance, while the 24 km course provides a more demanding night for stronger climbers on the same massif.
