Trail Els Esterregalls is a mountain trail race held in Isòvol, La Cerdanya, Girona. The event centers on the Esterregalls, a unique local landmark in Cerdanya which lends the race its name. The primary trail distance is approximately 21 km, recognized with a UTMB Index 20K listing. A recent measurement confirmed the course at 20.64 km with 848 m of elevation gain.
The race also provides shorter distances, including 11 km and 15 km routes, in addition to the main 21 km trail. The Esterregalls area is more than just a name; organizers describe it as an emblematic location and one of La Cerdanya’s most distinctive landscapes, serving as a focal point for the mountain route. A recent edition saw 200 finishers, contributing to its atmosphere as a local trail event rather than a large-scale race.
