You may wonder why we call our company Ha Ha Racing Events. "Ha Ha" comes from Ha Ha Tonka State Park–home to our very first race in 2018, the Ha Ha Half Marathon. Ha Ha Tonka State Park is located at Lake of the Ozarks in central Missouri. New in 2022, LOZ Traverse. This is our first ultra. Approximately 34 miles of running and 3 miles of paddling in Lake of the Ozarks State Park. Head to our UltraSignup Page and look for Lake of the Ozarks Endurance Runs for additional information. If you have any questions, don't hesitate to reach out to me at


Be well,

John Shelby, race director
