San Sebastián Marathon
The San Sebastián Marathon (Donostia Marathon) draws about 3,000 finishers each November along the Basque Country's stunning Bay of Biscay coast. The course passes La Concha beach, the Kursaal Congress Centre, and the Gros district with views of green hills and the Cantabrian Sea. November cool weather and rolling coastal terrain make it one of Spain's most scenic regional marathons.
Next race: Sunday, 15 November 2026
