The Big Cottonwood Marathon & Half Marathon takes place in Salt Lake City, Utah, with courses that run from Big Cottonwood Canyon down into the city and finish at Cottonwood High School. Both courses are paved and USATF certified.

The half marathon begins just below the Mill D parking area and follows a downhill route alongside Big Cottonwood Creek for nearly 10 miles to the mouth of the canyon. The half has approximately 2,856 ft of elevation loss, is paved, and is served by 7 aid stations. Its certification number is UT23007TJD.
