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. Registration for all our races can be found on Our logos on the home page of this website will link you directly to each race's UltraSignup page. 


If you have any questions, don't hesitate to reach out to me at


Be well,

John Shelby, race director
