View full details at RunFirefly.com

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!

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.

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.

Reflective gear, glow-sticks, and body-paint are encouraged.

The Firefly Overnight Endurance Challenge, starts at 8:00pm, on the Rocks and Roots trail at Alum Creek. The clock stops at 8am for the overnight challenge. Only completed laps count towards mileage.
