La Nocturne du Val Joly is a night trail and Nordic walking event held in Eppe-Sauvage, located in the Nord department of Hauts-de-France, close to the Val Joly area. The event takes place in mid-October and features two short off-road routes: a 10 km trail run and an 8 km Nordic walk.
The 10 km trail is the primary running event and the most attended option. Both routes are designed as single loops, providing participants with one full circuit instead of multiple laps. The prior event attracted over 200 participants, creating an atmosphere akin to a community autumn night gathering rather than a major urban competition.
