About this race
Run as many 800m loops as you can in 24 hours, each with 30m of elevation gain. This ultra-trail and backyard mix challenges you to string together laps. Test your summer training solo or in a relay (duo, trio, or quartet). The course is straightforward, but Les 24h du Fer à Cheval will truly test you after 24 hours.
