The Next Loop Endurance Series- Tyler, TX Nov 2026

The Next Loop Endurance Series in Tyler, Texas, is a November trail race at Tyler State Park centered on a single, repeated 3.1-mile dirt singletrack loop. Participants begin together, completing one 5K-style lap at a time, continuing until they reach their chosen distance, opt to stop, or reach the event's limit. The Tyler event also features 40-mile and 50-mile distances, each with a 12-hour time limit, allowing the race to serve as an initial trail test, a supported long run, or a complete ultramarathon endeavor. The loop crosses the pine forests of East Texas, featuring winding paths, tall pines, undulating terrain, consistent ascents, smooth runnable sections, shaded areas, and intermittent lake vistas. A central start-finish point functions as the aid station each lap, providing runners consistent access to hydration, nutrition, crew assistance, race personnel, and personal staging spots. The repetitive loop design eliminates navigation concerns, shifting the focus to pacing, fueling, and determining if another lap is feasible. Each completed lap is recorded, and the format is designed for runners of varying experience, from novices to ultra athletes honing their patience over numerous circuits.
