Runners follow an out-and-back course for the Mountain Madness Half Marathon, which starts and finishes at the Howelsen Ice Arena on Howelsen Parkway. From there, runners head onto River Road and head south for the next 2 1/2 miles, until they turn onto Aspen Ridge Road. The course follows Aspen Ridge Road for the next three miles — and takes runners up and down the race’s steepest hill — before heading back onto River Road, and then back toward the race finish.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
