Overview

The Mighty Mo Run returns for a three-day weekend in Sioux City, IA. Launched over a decade ago, this signature race now features a Kids Run, 5K, 10K, and the “Stooge” challenge—complete all three distances for a unique award—supporting the local H.A.R.T. Foundation (Helping Athletes Run & Train).

Course highlights include a start/finish at the Siouxland Expo Center, looping alongside the scenic Missouri River Trail, through Chris Larson Park, then back after crossing into South Sioux City and returning via Floyd’s Monument area. The route is distinctly flat, fast, and fun, perfect for PR-chasing or relaxed pacing—and rated highly by RaceRaves for its smooth surfaces and community feel.

Participants enjoy chip timing, eye-catching tech shirts, and medals. Weekend options include the 5K (Friday evening) and 10K (Saturday morning), with a combined challenge for three-day runners. Registration is tiered: half marathon fees start at $70 (plus $5.20 fee) through June 27, increasing afterward. Refunds are not offered, but optional race insurance can be added.

What makes it stand out? The festive weekend atmosphere, scenic river views, and a flexible multi-distance format. It’s a rare mid-September race with a competitive edge, scenic charm, and community heart.
