The Firefly Overnight Endurance Challenge & 10k Trail Race

✨ Race Overview

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!
