The Tout Cattenom Court by Night is a 13 km night trail run held in Cattenom, Moselle. It typically takes place on a Saturday evening in October. The start and finish points are located at the Mirgenbach reservoir parking area on the D56. Runners navigate forest trails and paths after dark, with an elevation gain of 195 meters. The entry fee has been listed at 15 EUR, maintaining the character of a local trail event rather than a large-scale production.
The route incorporates the darkness into the race itself, requiring participants to use headlamps. The course features a section through the Galgenberg structure. A past edition attracted 369 participants, with Mathéo Legay finishing first in 52:06 and Elodie Frank leading the women in 1:01:37. Although the event is in its early stages with its third edition, the combination of forest running, night conditions, and a consistent 13 km distance establishes its distinct identity.
