CdM Nocturna Feria de Mora is a night mountain race held in Mora de Rubielos, a village in Spain's Teruel province, Aragon. Participants venture into the Sierra de Gudar after sunset, choosing between two trail distances: 10 km with 320 m of elevation gain, or 16 km with 550 m of elevation gain. The event also offers a 10 km hiking category mirroring the short race's climb, alongside children's races ranging from 500 m to 3,000 m.
The start and finish line are situated in Plaza del Ayuntamiento, placing the race's beginning and end at the heart of Mora de Rubielos. The courses are loop-style, utilizing mountain trails, with trail marking and medical assistance available. Participant numbers are limited to 300 for each adult category and 200 for the children's events, maintaining a local feel. The Ayuntamiento de Mora de Rubielos coordinates the race, supported by the Servicio Comarcal de Deportes de la Comarca de Gudar-Javalambre, with registration managed via Runatica. The race's nickname, "Les demons de minuit," accurately reflects its nature: a headlamp-lit trail run after dark, distinct from a daytime road race.
