Prepare to push your limits at The Next Loop Endurance Series - 50 Mile Challenge, a demanding trail ultra set to take place on Saturday, March 14, 2026, in Shreveport, Louisiana. This continuous 50-mile race, distinct from the series' hourly loop format, challenges experienced endurance athletes to complete 16 loops of a scenic 3.1-mile (5K) trail.

The clearly marked trail-based course provides a consistent challenge, with minor distance variations expected due to the terrain. Runners will benefit from a dedicated 50-Mile staging area located at the central start/finish point at 8400 Mike Clark Rd, Keithville, LA. Comprehensive athlete support includes an aid station conveniently located every 5K loop, offering access to personal staged gear each lap, alongside continuous medical and safety oversight.

Your progress will be meticulously tracked with chip timing, providing splits for every completed 5K loop to help you manage your race strategy. Pacers are permitted after 4:00 PM, offering crucial support as you navigate the final stretches of this pulse-pounding trail race. The Next Loop 50-Mile Endurance Challenge is an ideal opportunity for ultra runners to push their boundaries and experience the thrill of endurance racing in a supportive setting.
