“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.

Louisville Race Club started in 2018 when four friends recognized a gap in their city's running landscape. They wanted a crew built on radical inclusivity, so they founded one. Now roughly 100 runners of all backgrounds and paces gather regularly, united by a simple mantra: Run As You Are. There's no gatekeeping here, no qualifying times, just people who show up for each other and the miles. The crew meets every 1st and 3rd Saturday at Gravely Brewing for a 5K, a ritual that's become the heartbeat of Louisville's most welcoming running community.
