The Trail au clair de lune - Moyaux is an evening nature trail race held in Moyaux, Calvados. Runners start from Place de l'Eglise, with race check-in at the Nicolas Batum complex. Two distances are available: 18 km and 10 km. Both races begin after dark, requiring participants to present a working headlamp and a reflective armband to receive their bib. This event, now in its eighth edition, is organized by Moyaux Intercom Basket.
The course is predominantly off-road, consisting of approximately 90% trails, paths, and woodland, with only 10% on paved roads. The 18 km race is open to juniors and older categories, while the 10 km race also accommodates cadets, making it suitable for younger trail runners. All participants have a 2 hour 30 minute time limit; those exceeding this duration will be removed from the official results. One euro from each entry fee is donated to the Moyaux Firefighters Association, directly supporting the local volunteer firefighters.
