Trail El Calero 2026

Trail El Calero is a mountain race held in Barruelo de Santullán, Palencia province, northern Spain, in early October. The primary option is a 25 km trail covering 1,000 meters of elevation gain, demanding strong mountain running ability despite its moderate distance. An 8.4 km trail route and an 8.4 km walking event are also available, offering a shorter alternative for participants seeking the same environment without the extensive climbing. The event is a component of the Palencia Trail Series, serving as a late-season fixture. Descriptions indicate a challenging mountain day for around a hundred participants, fostering a local mountain gathering atmosphere rather than a large-scale competition. Organized by the Ayuntamiento de Barruelo de Santullán and the local neighborhood council, all formats are non-competitive, emphasizing community engagement, even with the significant elevation on the 25 km course.
