The New Next Loop 40/50 Mile Challenge is a gritty, no-nonsense test of pacing and patience on a scenic 3.1-mile (5K) loop trail. This is a continuous 50-mile trail race run alongside The Next Loop Endurance Series. Same fully stocked Start/Finish aid station every lap. Easy fueling. Simple logistics. All the support, every time through. You’ll knock out 16 loops to hit 50 miles (trail measurements may vary slightly). A 12-hour cutoff keeps things moving and rewards smart pacing, with steady energy and a strong community vibe all day long. You can stage gear at your vehicle or in the designated staging area. Pacers are welcome after 4:00 PM.
