Athletes will experience expansive views and minimal traffic before heading into the City of Omaha and finishing near the Missouri River.

Run: Athletes’ 13.1-mile run will take them on paved trails along the Missouri River, followed by the famed Bob Kerrey Pedestrian Bridge heading over into Council Bluffs.
