Yuma Territorial Marathon

The Yuma Territorial Marathon runs along the Colorado River in Yuma, Arizona. Three road distances are offered: a 10K, a half marathon (13.1 miles), and a full marathon (26.2 miles). The riverside setting gives the course a scenic backdrop as runners make their way through the Yuma area, with the Colorado River providing a consistent visual thread across all three distances. Whether tackling the shorter 10K or going the full 26.2 miles, runners get a straightforward desert-river course that highlights one of southwestern Arizona's most notable natural landmarks.
