This captivating event invites runners to experience the magic of night racing across the renowned Rocks and Roots trail at Alum Creek State Park. Choose your challenge: push your limits in the 12-Hour Overnight Endurance Challenge, or embrace the starlit beauty with the 10K distance, available as both a Sunset and Sunrise option.

What truly sets the Firefly Overnight Endurance Challenge apart is its unique overnight format, where runners navigate a single-track course under the glow of the moon and, of course, the enchanting fireflies. Headlamps and flashlights are mandatory for this nocturnal adventure, and participants are encouraged to embrace the festive atmosphere by donning reflective gear, glow-sticks, and even body paint.

The start and finish are conveniently located at the Alum Creek State Park Group Campsite, serving as race headquarters. Aid stations are fully supported, and dedicated zones are available for crew and drop bag tents at the lap point, ensuring runners have access to essential supplies throughout the night.

With typical race day conditions seeing highs around 85°F and lows around 64°F, alongside a 20% chance of precipitation, runners can anticipate a warm but potentially humid overnight experience. The community atmosphere is further enhanced by the option for participants and their families to reserve campsites near the start/finish line, fostering a shared sense of camaraderie and support throughout the challenging hours. This event offers a compelling blend of endurance, natural beauty, and a truly unique night running experience, whether you're aiming for a personal best or simply running in the dark with friends.
