Minnie Ha Ha 12 Hour Run

The Minnie Ha Ha 12 Hour Run is a timed ultra running event held annually at Minnie Ha Ha Park in St. Louis, Missouri. The race features a USATF-certified, 1.17-mile paved loop course that winds through a mostly flat, wooded park with scenic views of the Meramec River and vibrant fall foliage.

The start and finish are located at Shelter "E," with convenient parking, restrooms, and a playground nearby. Aid stations provide ample fluids and food typical of ultra events. The race promotes environmental responsibility by being cupless, requiring runners to bring their own hydration gear.

All finishers receive medals, with awards for top overall and age group winners. Visit the organization's website for the most recent information.
