San Sebastián

San Sebastián sits on the Basque coast where the Pyrenees drop to the sea, giving runners steep climbs inland and the flat Concha beach promenade as default training ground. Cyclists own this city—the Clasica Ciclista San Sebastian is one of Spain's toughest one-day races, threading 100km through the sharp Gipuzkoa hills with repeated 6–8% gradients, while the Clásica Haimar Zubeldia pushes into the mountains for 150km of Basque climbing. The local duathlon scene is serious too, with trails like Aiako Mendi offering short, punchy elevation tests that suit the landscape's steep terrain.
