Minnie Ha Ha 12 Hour Run

The Minnie Ha Ha 6 & 12 Hour Run is an annual timed race held at Minnie Ha Ha Park in St. Louis, Missouri. Participants can choose between a 6-hour or 12-hour race on a USATF-certified, 1.17-mile paved loop course that offers scenic views of the Meramec River and surrounding fall foliage.

The event features chip timing, an aid station stocked with refreshments, and unique swag for all participants. In an effort to promote environmental sustainability, the race is cupless, requiring runners to bring their own hydration solutions. Awards are given to top finishers in various categories, and all finishers receive a medal. Visit the organization's website for the most recent information.
