The Next Loop 50 Mile Challenge — Cliff Cave

The Cliff Cave 50 Mile Challenge is a rugged, rhythm-driven test of endurance set on a scenic 3.1-mile loop weaving through the wooded trails and limestone bluffs of Cliff Cave Park.

This is a continuous 50-mile trail race held alongside The Next Loop Endurance Series—same fully stocked Start/Finish aid station every lap, seamless access to fuel, and simple, repeatable logistics that let you stay locked into your effort.

You’ll complete 16 loops to reach 50 miles (trail distances may vary slightly), with a firm 12-hour cutoff that rewards smart pacing, steady energy, and mental resilience as the day unfolds.

Stage your gear at your vehicle or in the designated athlete area, dial in your strategy lap by lap, and settle into the flow. Pacers are welcome after 4:00 PM.

Whether you’re chasing a breakthrough performance, stepping up to your first ultra, or just looking for a long, honest grind on trail—the Cliff Cave 50 Mile Challenge delivers a raw, focused ultra experience, one loop at a time.
