Trail Nocturno 4 Lobos y 3000 Buitres

Trail Nocturno 4 Lobos y 3000 Buitres is a night trail-running event held in Serradilla, within the Cáceres province of Extremadura, Spain. It takes place on a late-June weekend and provides two non-competitive options: the 22 km Trail Nocturno and the shorter Cross Nocturno, measuring approximately 9 to 9.6 km. The format is straightforward: participants select either the longer mountain trail or the shorter night cross route. Official maps, elevation profiles, route notes, and regulations are provided by the organizers. Now in its eighth edition, the event has an established rhythm as a local race, and its name directly references the wild surroundings of Serradilla, evoking four wolves and three thousand vultures.
