San Sebastián Marathon

The San Sebastián Marathon is one of Spain’s fastest, attracting runners looking for a personal best in a scenic coastal setting. With a flat course that weaves through the elegant streets, beachfront promenades, and lively neighborhoods of Donostia, the race combines performance with cultural charm. Cheered on by enthusiastic locals and cooled by the sea breeze, this late-autumn marathon is a must-run in the Basque Country.
