Mighty Mo Run

The Mighty Mo Run is Sioux City, Iowa’s premier running event, offering a variety of races including a Kid’s Fun Run, 5K, 10K, Half Marathon, and a unique “Stooge” run for participants who run all three days. All courses are flat, fast, and fun, starting and finishing at the Seaboard Triumph Foods Expo Center and running along the scenic Missouri River Trail. The event features certified courses for the half marathon and full marathon (returning in 2026).

A Health and Wellness Expo accompanies the races, showcasing local fitness and nutrition vendors. Proceeds support the H.A.R.T. Foundation, aiding athletes in training and running. Visit the organization's website for the most recent information.
