Zurich San Sebastián Marathon

The Zurich Maratón San Sebastián is a city-centre marathon held in Donostia - San Sebastián that returns on 22 November 2026. The race uses a three‑lap urban circuit introduced in 2022 that the organisers describe as more central, more touristic, faster and flatter; the course runs along the Urumea river promenade and the bay of La Concha. The route takes in key landmarks such as Victoria Eugenia Theatre, Anoeta Stadium, the Cathedral of the Buen Pastor and the Kursaal, and finishes on the Boulevard with a long flat run-in ideal for fast finishes.

This edition is organised by RPM MKTG S.L. under the Zurich San Sebastián Marathon brand and features the event expo, pre‑race bib collection and participant services across the race weekend. The official event website provides course maps, registration and practical information for runners and visitors, and the weekend is promoted as a combined sporting and cultural experience in the Basque city.
