Cross 3 Playas 2026

Cross 3 Playas is a 10-kilometer race in Donostia / San Sebastián that follows the city’s three beaches. It is a flat urban run, suitable for experienced runners seeking a steady rhythm and for newer runners wanting a straightforward course without climbs. The route stays close to the coast, offering a beach-by-beach view of the city instead of heading into the hills surrounding San Sebastián. It is one of the older races in the city, having reached more than thirty editions. Recent fields have also stood out for their gender balance: more than half of the 10K entrants are women, with female registrations ahead of male registrations for a second straight edition.
