Approximately 2,000 cyclists participate in this annual bike ride – a week-long trek through some of Colorado's prettiest country, sponsored by the Denver Post. The route changes every year, keeping cyclists on their toes! If you're used to navigating Denver's city streets on two wheels, you'll enjoy this rural change of pace. While the registration can seem pricey, keep in mind that it covers a host of amenities, such as camping space, showers, restrooms, shuttle transportation, aid stations and medical support en route.
