The Blasimon Trail 24h is a trail race held in Blasimon, a commune in Nouvelle-Aquitaine in southwest France. It takes place over a Saturday-to-Sunday weekend in October. The race format uses a short loop of approximately 6.7 km, with categories for solo runners, duos, and teams of four.
The route follows winding trails around Blasimon, passing through forest and vineyard sections in the Entre-deux-Mers region. Since all participants cover the same loop, the event accommodates various strategies: a solo runner can focus on their personal distance goal, while duos and four-person teams can divide the laps to maintain continuous running throughout the weekend.
