Marcha de Montaña Demandasaurus 2026

The Demandasaurus Mountain March is a medium-mountain athletics event held in Salas de los Infantes, Burgos province, Spain. It takes place over two days in October, offering formats for runners, walkers, and mountain bikers, not just a single race distance. The schedule includes trail runs, a non-competitive march, and BTT mountain-bike options, with distances ranging from 10 km to 41 km. The shorter trail races and the 13 km march are non-competitive, allowing participants to enjoy a mountain route without the pressure of racing for a position. The Ayuntamiento de Salas de los Infantes organizes the event, and the "XII" edition number indicates it has a history of multiple previous events.
