The Next Loop Endurance Series - Shreveport, LA 2026

The Next Loop Endurance Series near Shreveport directs runners onto a consistent 3.1-mile trail loop from a central base in Keithville. A new loop begins each hour, and runners decide after each loop whether to continue or conclude with a recorded result. Completing one loop equals a 5K, two loops a 10K, four loops a half marathon, nine loops a marathon, and ten loops a 50K. The format integrates pacing and recovery into the race itself. Each loop receives an official time, and rankings are based on loops completed and total time, without penalties for stopping or missed cutoffs. The course is marked, an aid station is provided hourly, and the central location is convenient for crews and families observing the runners. The event accommodates first-time distance runners, marathoners, ultra runners, and hybrid athletes using the hourly structure to gauge endurance under fatigue.
