The Sylver Trail is a nature running event held in Bois-le-Roi, a village within the Eure department of Normandy. It provides three race distances suitable for various skill levels, commencing at the village's multi-purpose hall.
The courses traverse paths and trails winding through the Norman forests surrounding Bois-le-Roi. This edition takes place at night, requiring participants to use headlamps and offering a more subdued encounter with the forest compared to a daytime trail race.
