Endure Trail Runs

The Endure Trail Runs at Mueller State Park is an endurance event featuring a unique 12-hour challenge where participants draw colored balls to determine their running loops. The event also includes additional race options: a 10k, Half Marathon, and Marathon. These events allow participants to experience the park's natural surroundings with the support of an accommodating time limit. All courses consist of double-track and single-track trails, promising a pure trail running experience with no pavement. Participants can enjoy a well-equipped aid station throughout the event. The event was previously known as The Tommyknocker 12-Hour & Mine Shaft Half.
