Sioux City, IA-NE-SD

Sioux City sits at the confluence of the Missouri and Big Sioux rivers in the tri-state region, with mostly flat to gently rolling terrain ideal for distance running. The Mighty Mo Run courses follow the Missouri riverbank and are the area's signature events; runners also use the LeClaire Park trails along the water. Cyclists tackle the Cone Park Trail Fest routes for technical singletrack, though most road cycling heads north toward the Loess Hills for rolling terrain and scenic overlooks.
