Choose from dozens of single-track mountain biking trails on an interactive map of the Boulder/Denver area of Colorado. Sections of the Colorado Trail between Denver and Breckenridge are also included, and are split out in such a way that every mile open to bikes can comfortably be ridden without missing any of what is arguably the best single-track in the area. Icons color coded by difficulty and trail status display custom trail information and links to driving directions when selected. Driving directions show the way to all of the main trail heads, and in some cases multiple secondary access points, using device location services. Primary and secondary trail maps are available for most rides. An alphabetical list provides a means to locate a trail on the map, visit its official website, and enter the date and duration of a ride. For more specific information, such as trail descriptions and photos, a separate more detailed trail list is included as well.
