Get ready for an exhilarating weekend at the Mighty Mo Run, taking place from Friday, September 12th to Sunday, September 14th, 2025, in the vibrant Sioux City, Woodbury. This premier running event in Iowa offers something for everyone, featuring a Kids Run, a fast-paced 5K, a challenging 10K, and a scenic 1/2 Marathon. All courses are designed to be flat, fast, and fun, starting and finishing at the Siouxland Expo Center while meandering along the picturesque Missouri River Trail.

Participants will be thrilled to discover that this year brings exciting new awards, and your participation will help support the H.A.R.T. Program, which is dedicated to helping athletes run and train. While the full marathon is on hold until 2026 due to course reconstructions, the updated 1/2 Marathon route promises a fantastic experience for runners of all levels. Join us for a weekend of fun, fitness, and community spirit at the Mighty Mo Run, where your run can make a difference!
