Planning a marathon in Colorado just got easier. Explore the Rockies, Pikes Peak, and cross the Continental Divide by foot and compete at a higher elevation in a Colorado marathon. Enjoy the view, fresh air, and thrill of competition as you scale the mountainside. Run alongside other runners enjoying the view from 14,000 foot peaks and down near the Colorado River.  The Centennial State's race courses feature a scenic drive across its capital Denver; various outdoor activities in Aspen; the home of the University of Colorado, Boulder; and the 2018 U.S. News' most desirable place to live in the United States, Colorado Springs, among others.
