The Foulées des Barthes is a trail race in Tercis-les-Bains, located in the Landes department of southwest France. Participants can select either a 5 km or a 12 km course. Both races commence at 9:30 AM, positioning the event as focused on short off-road distances, distinct from road racing or extended mountain trails.
The Comité des Fêtes de Tercis, the local festival committee, is responsible for organizing the race. This community-driven approach lends the event a local feel, differentiating it from major commercial race series. Approximately one hundred participants typically take part, and historical results indicate the race has been a consistent fixture on the local running schedule for several years.
