The Next Loop Endurance Series - Tyler

The Next Loop 40/50 Mile Challenge : Tyler State Park

The Next Loop 40/50 Mile Challenge is a continuous-loop trail endurance event held at Tyler State Park on November 14, 2026. The race runs on a 3.1 mile (5K) loop of forest singletrack through tall pines with rolling terrain and occasional lake views. Trails are described as well maintained dirt surfaces with steady climbs, smooth runnable sections, and enough elevation change to require strategic pacing.

The format uses repeated laps around the same loop, with a central staging and aid area that provides regular access to hydration, nutrition, crew support, and race staff. Aid is fully stocked each lap and personal staging areas are designated near the start and finish to simplify logistics and support between laps. The event emphasizes consistent footing and continuous access to resources.

Distances offered are:

• 40 Mile
• 50 Mile with a 12 hour cutoff

The event is presented for a range of participants, including runners attempting their first ultra distance, athletes stepping up from a marathon or 50K, and experienced ultrarunners who prefer a simplified, fully supported loop format.
