About this race
Run through the dark, celebrating the firefly. Tackle the Rocks and Roots trail at Alum Creek, the only trail in central Ohio built by runners, for runners. This supported, overnight challenge is a chance for running in the dark with friends. Headlamps are mandatory; glow-sticks and body-paint are encouraged. Grab an extra credit lap for bragging rights only during The Firefly Overnight Endurance Challenge.
