Course & Elevation
The half marathon of the Bilbao Night Running Fest is a night-time city race in Bilbao, held on a Saturday in mid-October. The festival, known as the Bilbao Night Marathon until 2024, dropped the full marathon in 2025 and now has a half marathon and a 10 km 'Carrera Pirata'. It is organised by the Club de Atletismo Bilborun, with production by Streetmarketing Event Company, and the half marathon is an RFEA-measured, single-lap 21.097 km course. Runners start in waves from 19:00 on the esplanade by the San Mamés stadium and finish beside the Guggenheim Museum. The route passes the Euskalduna Palace, the Gran Vía, the Arriaga Theatre, the Casco Viejo, the City Hall, the Isozaki Towers and the Zubizuri bridge by Calatrava. The 2026 edition was the 18th and drew a record 27,000 runners across both distances, from 76 countries. The time limit is 2 hours 45 minutes. The men's record is 1:00:34, set by Deogracius Musobo in 2026. The 2027 race, set for 16 October, will open with a cap of 20,000 entries.
