Night City Trail is a night race series in Torrelavega, focused on exploring the city after dark on foot or by bike. It is noted as the first urban night trail race, with a decade of history. Participants can choose from several options: a 15 km trail for running or walking, a 40 km MTB/eBike route for adventure cyclists, team entries over 15 km, and a shorter 7 km route suitable for families, walkers, and inclusive participation.
The course format is urban trail, distinct from a standard road race. The appeal lies in viewing Torrelavega from a different perspective while navigating the city at night. The team category requires a minimum of five people, facilitating entry for clubs and groups of friends. The 7 km route is intended for a relaxed walking pace, while the longer trail and bike routes offer a more challenging option for runners and cyclists.
