Trail Nocturne et Ultra Trail de la Sibérie

About this event

This Belgian winter event offers something rare: a collection of nighttime trails through the forests of Profondeville, paired with serious ultra distances for those seeking a bigger challenge. The nocturne races range from a friendly 6km with headlamps to a 25km adventure, making it an accessible introduction to night running. For experienced runners, the ultra options stretch up to 160km with substantial elevation. The February timing adds a crisp, atmospheric quality to the forest trails, and the variety of distances means groups of mixed abilities can share the same event weekend. The beginner-friendly shorter routes provide a supportive way to discover trail running after dark.
