Winding over the Colorado National Monument from Grand Junction to Fruita, Colorado, the U.S. Bank Rim Rock Run boasts scenery unlike any other marathon. The peaceful course features views of towering monoliths, vast plateaus and canyon panoramas. Sheer-walled, red rock canyons surround the twists and turns of the course.

Half Marathon 

In addition to a marathon and marathon relay, the U.S. Bank Rim Rock Run also includes a Half Marathon featuring gravity-defying boulders, tunnels carved of stone and red-rock canyons! 

From the start at Highland View the net downhill Half Marathon course may be one of the fastest races you do! You’ll have 10 glorious miles of running downhill through the Monument before you reach the three mile flat stretch that takes you into the heart of Fruita.

All races finish in downtown Fruita’s Circle Park, at a celebration that includes live entertainment, local food, and a beer garden.

Proceeds from the U.S. Bank Rim Rock Run benefit scholarships for  Colorado Mesa University Track and Cross Country student-athletes and the Greater Grand Junction Sports Commission
