Sep'arty 2026

Sep'arty is a night-time urban trail run held annually in mid-December in Tréguier, Côtes-d'Armor, Brittany. The main event is a 10 km urban trail, complemented by an 8 km walk, attracting both runners and walkers, not exclusively trail specialists. The course winds through Tréguier's streets and alleys, with the 10 km race being the most frequented choice. Organized by Sport Nature Trégor, it functions as a charity event supporting the fight against multiple sclerosis. A distinctive aspect of its local character is the surprise element along the route; one past edition included a section with foam in Kercoz alley. The original organizing team concluded their ten-year tenure, marking a distinct local history for the event beyond being just a winter run.
