The San Sebastián Half Marathon 2025 It is not simply a sporting event. It is an appointment with the landscape, personal effort, self-improvement and the athletic character of a city that breathes sport. The next Sunday April 6, San Sebastián will once again become the perfect setting for thousands of runners, local and coming from all corners, to take on one of the most beautiful and fastest routes on the national scene.

An event that goes beyond running
With more than thirty editions behind it, the San Sebastian Half Marathon 2025 has established itself as one of the most attractive events in northern Spain. The route, the organization, the environment, the mild temperature of the Cantabrian Sea in spring and that very San Sebastián way of mixing sports with culture and aesthetics make running in San Sebastián a unique experience.
Date, distances and modalities
The race will take place on Sunday April 6, 2025, with joint departure for both modalities at 10:00 h from San Sebastián Boulevard. The two options available to runners are:
- Media marathon (21.097 km): the queen test, with a circuit of two identical laps and approved by the Royal Spanish Athletics Federation (RFEA).
- Carrera 10K: ideal for those starting out in the world of racing or looking for a more affordable distance.
Both tests share the essence of a practically flat profile, without pronounced curves, at sea level. This design makes the San Sebastian Half Marathon 2025 an ideal race both to enjoy and to look for a mark.
