Race Information
The Endure 12-Hour is a one-of-a-kind challenging 12-Hour timed event, designed by YOU… and tiny colorful balls. Runners pull colored balls from a bucket, determining the loop they’ll next run. This continues for up to 12 hours, and the runner’s result is the number of miles they ran within the allotted time.
The Endure 24-Hour is a one-of-a-kind challenging 24-Hour timed event, designed by THE COLLECTIVE… and tiny colorful balls. In this event, the 12-hour event meshes with The Last Man Standing type of event. Your task is to endure the full 24 hours with others. Two balls will be pulled before each loop. The first determines the colored loop the entire field will run, and the second determines the slowest possible pace that it can be completed.
The Half Marathon is a great way to get out and enjoy the natural beauty of Mueller State Park in a supportive “no-pressure” environment and features a generous 12-hour cutoff.
The courses are double-track and single-track trails with ZERO pavement and an aid station you’ll want to hang around at for hours!

😄 Why We Like This Run
✅ Breathtaking national park views
✅ Smooth, gentle route
✅ An unforgettable atmosphere
Lace up for 13.1 miles through the heart of Utah's red rock country. Starting on Kolob Terrace Road in Virgin, Utah, this gently rolling, point-to-point course follows the Virgin River, just two major turns stand between you and the finish, as towering sandstone walls and endless desert views build with every mile.
It's bold. It's beautiful. It's unforgettable. And it ends right where the adventure should: at Cable Mountain Lodge in Springdale, staring at the South Entrance of Zion National Park. Beat the 10/31 price increase!
