Marathon de San Sebastián

The Marathon de San Sebastián is a road marathon held in late November in Donostia-San Sebastián, located on Spain’s Basque coast. It holds the distinction of being the second oldest marathon in Spain. The route is entirely urban, remaining flat and at sea level. A 10K race is also conducted on the same day, accommodating newer runners and faster short-distance athletes alongside the marathon participants. The course winds through the city, passes by the bay, and extends to the eastern part of San Sebastián. This path offers participants city streets and coastal vistas with minimal elevation gain. The flat course attracts those aiming for personal best times, and local runners consider the marathon a significant objective; the city’s mayor likened it to a pinnacle for runners from San Sebastián. Both first-time marathoners and seasoned runners seeking fast times benefit from the spectator and runner support along the course, which aids momentum.
