La Villardaire begins at 6 PM in Villars, with runners starting from the Salle de la Libération after dark. This is a trail foot race on natural paths, organized by the Villars Running association, offering two distance options: 12 kilometers and 17 kilometers.
The routes have been updated, and the organizers incorporated new sections after receiving permission from local farmers. This detail lends the race a local, practical character; it is not merely a road loop but a night run shaped by the countryside and the landowners who grant access.
