Runners begin at the stadium's base and conclude inside it for the 15 km Salto Donostia - San Sebastian, a road race held in October in San Sebastian, Spain. The primary race is 15 km at 10:00, preceded by a 5 km run at 09:30 and a distinct 15 km rollers and handbike competition. The 15 km event draws a substantial field, with the latest recorded results showing 3,892 participants for that distance.
The course is designed for speed, described by the organizer as an ultra-fast layout, yet it still offers participants a comprehensive view of Donostia. It proceeds north from the stadium, traces the Urumea river, crosses historic bridges, goes through the city center, and then runs alongside La Concha Bay before incorporating a short, elevated loop for added challenge. The ambiance is distinctly Basque and local, featuring music and hand claps along the route, and the stadium finish provides a defined endpoint, unlike a less distinct seafront conclusion.
