From the Organizer
“Where the miles meet the wild.”
The Falls & Forest 12‑Hour Challenge invites runners to push their limits in one of Kentucky’s most scenic and rugged natural playgrounds: Saunder Springs Nature Preserve. This endurance test winds through shaded forest trails, rocky climbs, creekside paths, and the iconic waterfalls that make this preserve unforgettable. You can run solo, as a 2-person team, or 4-person team.
Runners will have 12 full hours to rack up as many miles as they can on a beautiful, challenging loop course that blends technical footing with fast, runnable sections. Expect August heat, dense summer greenery, and the kind of grit that only a Kentucky trail can demand.
Whether you’re chasing a mileage PR, testing your ultra legs, or just looking for a full‑day adventure in the woods, this event delivers a uniquely immersive experience. Aid, support, and encouragement will be waiting each loop — but the real challenge is between you and the trail.
Falls. Forest. Twelve hours. One incredible day on the trails.
