Mighty Mo Run

Mighty Mo Run is a multi day running event in Sioux City, Iowa held September 11–13, 2026. It includes a full marathon, half marathon, 10K, 5K, a kids run for ages 12 and under, and a Stooge challenge that recognizes participants who run across all three days.

Courses are described as flat and designed for speed. The route network is scenic and crosses portions of Iowa, Nebraska, and South Dakota. The event uses an indoor start and finish at the Seaboard Triumph Foods Expo Center and continues along the Missouri River Trail near the venue.

Support features listed for participants include multiple aid stations stocked with fluids, support, and restrooms; showers and a recovery station after the race; and on-site refreshments. The half and full marathon courses are stated to be certified. The Stooge entry offers a unique award and a special t-shirt for those who complete events on all three days.

Proceeds from the event support the H.A.R.T. Foundation, an organization described as Helping Athlete’s Run & Train. Visit the organization's website for the most recent information.
