The Trail Nocturne de l'Ecoparc Catalan is a night trail race held in early December in Occitanie, Pyrénées-Orientales. Participants run through the Ecoparc Catalan area, near Villeneuve-la-Rivière, Pézilla-la-Rivière, Calce, and Baixas. The courses blend town running with open-country trail running. The distinctive feature is the illuminated setting: a large wind turbine park and the surrounding Mediterranean communes are specially lit for the race, making the event designed for running after dark, not simply adding headlamps to a standard trail route.
Five night-trail distances are offered: 7 km, 11 km, 22 km, 33 km, and 44 km. The 22 km, 33 km, and 44 km races are available as solo runs or as relays for teams of two, three, or four. The 7 km and 11 km options can also be completed as hikes. Over 2,000 people participated in the third edition, with the field intended to accommodate walkers, newer runners, relay teams, and longer-distance trail runners. Local residents from the four communes line the route to support participants. The runner pack includes an official jersey, a finisher medal, a 66 Degrés Sud bag, aid at the finish line, safety support on the course, and trophies for the winners.
