Join us at the Firefly!
Each and every year, one of the world’s most beloved bugs visits Ohio – proudly announcing their arrival with random sparks and flickers of glowing neon throughout the summer sky. Join us as we welcome and celebrate the most efficient light in the world… the firefly! (nearly 100% of the energy in the chemical reaction within the fireflies light organ is emitted light… it’s true)
Whether you’re looking to set a distance PR or just looking to run in the dark with some friends, “The Firefly Overnight Endurance Challenge and Sunset & Sunrise 10k” will offer you that opportunity with 12-hours of fully supported, overnight-racing throughout the ONLY trail in central Ohio built BY runners, FOR runners! Wait, what?!?! Overnight!?!?! Yes!!
When - Saturday/Sunday, June 27-28, 2025.
Where - Unlike other RRTRA events this event will start and finish at the Alum Creek State Park Group Campsite, which is located just off of Lewis Center Rd and just north of the beach entrance.
The race will start at 8pm, and it will be dark no matter which race you choose! So, even though the fireflies will help light your way, headlamps and/or flashlights are mandatory. Reflective gear, glow-sticks, and body-paint are encouraged.
Bring your family and friends, as the course will pass through the overnight group-camping area. Don’t forget the kids! They’ll have a race too! The kids mile will start promptly 30-minutes prior to the “big kids” race.
