The Experience

The Human Potential Running Series Presents: The Endure Trail Runs @ Mueller State Park The Endure 12-Hour is a one-of-a-kind 12-Hour timed event designed by YOU… and tiny colorful balls. Each runner will pull colored balls from a bucket, which determines the loop they’ll next run. This continues for up to 12 hours; the runner’s result is the miles they ran within the allotted time. You are not required to run for all 12 hours, as your final result is the number of miles you ran within the time you participate!  The 10k, Half Marathon, and Marathon are great ways to enjoy Mueller State Park’s natural beauty in a supportive, “no-pressure” environment. All three distances feature a generous 11-hour cutoff.  All courses feature double-track and single-track trails with ZERO pavement, and an aid station you’ll want to hang around at for hours (we’re that much fun)! Formerly Known As The Tommyknocker 12-Hour & Mine Shaft Half
