Ancient Oaks 100-Mile Endurance Run

The Ancient Oaks event is an invitation only, no-fee, low-aid 100.34 mile endurance run held in the Enchanted Forest Nature Sanctuary in Titusville, Florida. The 2026 race takes place the third weekend in December, on December 19-20, 2026, at 444 Columbia Blvd, Titusville, FL 32780.

The course is a 3.46 mile loop completed 29 times for a total of 100.34 miles. Runners must complete all 29 loops within a 32-hour time limit; there are no alternate finish options. Aid at the aid station is minimal and participants should expect water only.

Entry is limited to 60 runners by agreement with the park. Entry is by Invitation to Run: interested participants must request an invitation during the wait list period in June, and the entry list is drawn from that wait list. Invitations are sent by email on or about July 3, 2026. There is no entry fee. Volunteers at Ancient Oaks earn a guaranteed entry into a future race. The selection process for invitations is private and not disclosed.

Finishers receive a hand made award of undetermined form; a belt buckle is not offered for finishing this 100 mile event. Visit the organization's website for the most recent information.
