John Bryan Arboretum Trail Half Marathon & Challenge
This event takes place at John Bryan State Park Arboretum in Yellow Springs, Ohio on 25 July 2026. The course uses a 1.1 mile loop that participants repeat to reach their chosen distance.
Distances offered include:
- 1.1 Mile Fun Loop for beginners, walkers, and families
- 3.3 Miles (3 loops)
- 6.6 Miles (6 loops)
- 9.9 Miles (9 loops)
- 13.2 Miles (12 loops; half marathon distance)
Aid and facilities are located along the loop. A water and aid station is available every 1.1 miles, and park restroom facilities (park potties) are on-site. The course is described as a clear, easy-to-follow loop with frequent spectator presence.
The loop format gives runners repeated, consistent access to support and facilities during the event. This structure allows participants to monitor pacing and hydration at regular intervals and to complete the event by covering the required number of identical loops.
