The Next Loop Endurance Series | Tyler State Park
November 14, 2026 | Tyler, Texas
The Next Loop Endurance Series returns to Tyler State Park with two ways to challenge yourself on the trail.
The Next Loop Hourly Challenge is 5K. Every Hour. 10 Hours. Complete an approximately 5K loop every hour, on the hour. Finish within the hour, recover and refuel, then decide if you’re ready for One More Loop. Run one loop or all ten. No DNF—every completed loop counts.
The Next 12 Hour Challenge is continuous. Run, walk, or hike at your own pace for up to 12 hours and see how much distance you can cover. You decide when to run, rest, and refuel.
Whether you’re exploring endurance running for the first time or chasing a new personal goal, choose your challenge and discover how far you can go.
Your Endurance. No Limits. One More Loop.
