        Colorado is filled with trails for every rider and runner. From smooth, picturesque riverwalks to the most advanced rocky and technical downhills, Colorado is filled with natural beauty and challenge.

        With an adventurous attitude, Colorado takes its open spaces very seriously. All developed areas are planned with an eye for nature and a desire to keep things wild. There is a strong "Wildlife First" mentality that shows in its carefully designed and maintained trail systems.

        Colorado also hosts many road and mountain races. Foot races include the on and off-road marathons of Denver, Silverton, and Aspen. Towns like Durango, Winter Park, Vail, Cañon City, Crested Butte host pro mountain bike races. And the Iron Horse Classic cannot be ignored; road cyclists race the Durango-Silverton Railroad steam train over 5000 feet of elevation and 50 miles
