The Human Potential Running Series Presents:
The Endure 12-Hour is a one-of-its-kind 12-Hour timed event where runners choose loops based on colored balls they draw from a bucket. The result is based on the miles covered within 12 hours of participation.
The Endure 24-Hour event merges a 24-hour challenge with a Last Man Standing format. Participants need to complete all 24 hours or face disqualification. Loop and pace are determined by colored balls.
The Half Marathon & 10k races offer a supportive and no-pressure environment to enjoy Mueller State Park. Both races have a generous 12-hour cutoff time.
All courses feature double-track and single-track trails with no pavement, and include an aid station known for its enjoyable atmosphere.
Formerly Known As The Tommyknocker 12-Hour & Mine Shaft Half
