Les 24 Heures du Circuit d'Albi is a 24-hour road ultramarathon held annually in Albi, southern France, since 2013. Initially a June event, it later shifted to October. Amateur and professional runners compete simultaneously, with the winner determined by the greatest distance covered within the 24-hour period. The Association Albi24h organizes the event, directed by Didier Thiriot.
Participants race on a short road circuit, not between towns. The course was extended to 1,500 meters and widened in sections to accommodate international championships. Albi has previously hosted IAU European and World 24-hour championships, along with French championships, attracting national-team ultrarunners and open entrants. The event's record book includes notable performances: Aleksandr Sorokin achieved 278.972 km, Camille Herron set a world record of 270.116 km, and Erik Clavery established a French 24-hour record of 272.217 km. A 100 km race was subsequently introduced, commencing alongside the 24-hour event.
