Ancient Oaks 100-Mile Endurance Run

The Ancient Oaks 100-Mile Endurance Run is an invitation-only, no-fee, low-aid event held in the Enchanted Forest Nature Sanctuary in Titusville, Florida. The 2026 edition takes place the third weekend in December on December 19 to 20, 2026, at 444 Columbia Blvd, Titusville FL 32780. Entries are limited by a hard cap of 60 runners per agreement with the park.

The course is a 3.46 mile loop run 29 times for a total of 100.34 miles. The loop uses park trails and includes sections of asphalt, sand and grass two track, rolling wood chip trail, a short concrete path, twisty rooty single track, two boardwalk sections, a short bridge, a sharp 15 foot hill, and some loose sand. The trail will be clearly marked. The event is described as low aid.

Prospective runners must request an Invitation to Run by placing a Wait List request any time between 12:01 AM June 1, 2026 and 11:59 PM June 30, 2026; the Entry List is drawn from that Wait List, with Invitations sent on or about July 3, 2026.
