Ancient Oaks 100-Mile Endurance Run

Ancient Oaks 100-Mile Endurance Run starts at 7:00 a.m. on December 19, 2026, at the Enchanted Forest Nature Sanctuary in Titusville, Florida. It is a trail 100-miler, free to enter, run with minimal support and a strictly limited field. Entry is by invitation only: runners request a spot during a set window to join a waiting list, from which the starting field is drawn. There are no qualifying standards, the selection is made privately, and finishers do not receive a buckle.

Experienced ultrarunners are the audience here, especially those who are drawn to a stripped-down event rather than a production. With little on-course support, you need a plan for your own nutrition and gear, and a build that includes back-to-back long runs on trails over several months. Give the organizers an email address you actually check, since that is how entry news travels.
