The Great Divide Mountain Bike Route, paralleling the U.S. Continental Divide for 2,490 miles from the Canada to the Mexico Border, is the longest off-pavement cycling route in the world. This publication depicts 315.2 miles of the Great Divide Mountain Bike Route. Map A shows the route from Silverthorne to Salida, Colorado. Map B shows the route from Salida to Platoro, Colorado.

The maps include profiles, riding tips, geographical data, backcountry travel advice, general information, and a service directory. The directory locates groceries, restaurants, lodging, camping, and bike shops, both on and off the route.

The Great Divide was never envisioned to be a hard-core mountain-bike trail; rather, from the outset it was intended it to be suitable for loaded touring. Roughly 80% of the route is composed of county, Forest Service, and Bureau of Land Management (BLM) dirt and gravel roads. The remainder is made up of four-wheel-drive tracks and singletrack trails (10%), paved roads (10%).
