Mighty Mo Run

The Mighty Mo Run in Sioux City, Iowa, is a premier running event featuring a variety of races including a Kids Run, 5K, 10K, and Half Marathon. All courses are designed to be flat, fast, and fun, starting and finishing at the Siouxland Expo Center while following the scenic Missouri River Trail. Proceeds from the event support the H.A.R.T.

Foundation, which aids athletes in their training and running endeavors. Due to recent flooding, the full marathon has been canceled, but it is expected to return next year as a three-state marathon. Visit the organization's website for the most recent information.
