24 Heures de l'Ardèche - Guilherand-Granges 2026

The 24 Heures de l'Ardèche is a timed ultra-running event held in Guilherand-Granges, Ardèche, France. The primary race challenges participants to cover the maximum possible distance within a 24-hour period. Scheduled for late May, the event also offers 12-hour and 6-hour races, providing the same format for those preferring shorter durations. The event is organized by Marathon de l'Ardèche. A recent edition saw 100 participants, suggesting a more intimate, local timed-ultra gathering than a large-scale event. Entry fees are tiered according to race duration: the 6-hour race is the least expensive, followed by the 12-hour race, with the 24-hour race having the highest cost.
