Cold start — layer up, big temp swing

Runners will start in chilly 34°F conditions — dress in layers for the corral and plan to shed early. Temps will climb significantly to 59°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

About the REVEL Big Cottonwood Half Marathon

The Big Cottonwood Half Marathon is a point-to-point downhill course that starts just below the Mill D parking area in Big Cottonwood Canyon. Runners follow Big Cottonwood Creek between the canyon cliffs for nearly 10 miles, then pass under Wasatch Boulevard and run through Cottonwood Heights and the Old Mill Corporate Center. The course enters Holladay through Knudsen Park, turns onto Big Cottonwood Road, and follows Van Winkle Expressway and 5600 South to the finish at Cottonwood High School in Murray. It is a USATF-certified course run on the second Saturday of September, and its steady descent makes it one of the faster half marathons in Utah.
