La Bardoise is a rallye-trail in Bard, a village in the Loire, organized by MJC Loisirs au Village. Its primary format is a 23 km nature run with timed trail sections and untimed liaison sections covered at a free pace, making it resemble a small adventure event more than a standard trail race.
The routes traverse Bard’s hills and natural paths, offering options from very short courses to a 23.05 km route with 767 m of elevation gain. Participants start and stop each timed section using an electronic finger system, similar to that used in multisport raids and orienteering. The event welcomes novices, experienced runners, competitors, amateurs, families, and nature-running enthusiasts. The morning concludes with a local meal. The race, initially a first edition organized by the village MJC, has since reached at least its tenth edition.
