Cross Solidario San Silvestre 2026

The Cross Solidario San Silvestre is a 4 km run in San Agustín de Guadalix, a town in Spain's Madrid region. It is a non-competitive event, emphasizing participation over competition. Its San Silvestre designation connects it to the end-of-year running tradition. The route begins and ends in San Agustín de Guadalix, ensuring the event remains contained locally and is straightforward to navigate. The charity aspect is integral to the format, meaning participants join a brief community run with a social aim, distinct from a formal road race.
