Tour of the Moon Ride Information
Tour of the Moon was made famous in the 1980s Coors Classic and later in the cycling movie American Flyers. Its legacy continues as one of the premier road cycling events in the western United States, which showcases the Colorado National Monument and its towering monoliths, sheer-walled red rock canyons, and panoramic views.

Courses
Tour of the Moon includes two courses, a 41-mile option and a 64-mile option.

All cyclists will start and finish at the Grand Junction Convention Center in downtown Grand Junction. The ride will begin with a spectacular trek through the Colorado National Monument. After exiting the Monument, riders may elect to tackle a metric century through the beautiful farm country and surrounding areas of Fruita, or hang a right and wind their way back to downtown by way of quaint country roads and a jaunt through the Redlands.
Registration
Tour of the Moon Registration is capped at 2,200 participants, so be sure to sign up early. A portion of registration fees supports One Riverfront and Bicycle Colorado. The Ride Collective’s Tour of the Moon ride has been a proud Champion Event Member of Bicycle Colorado, supporting advocacy work across Colorado for safer biking.

Commemorative Cycling Jersey or Tech Tee
Entry into the Colorado National Monument
Bike plate & bib
Amply stocked aid stations with healthy and energizing refreshments
Post-ride celebration to include lunch, beer garden, expo, and entertainment

Check out the latest cycling gear, accessories, and nutrition products. You’ll find great bargains on apparel, equipment, and more. Inform your friends and family that the expo is also open during the ride itself, so while you are on the course, they can enjoy the exhibits.
Lunch is open to all Tour of the Moon participants. The tag off your bib is your lunch ticket, so please keep that intact until after lunch.

It’s the perfect long ride for a modern road bike, covering cell-signal-free country with the security of aid stations and police traffic control. The shorter “Dall Sheep” course is an out and back of 31 miles, with a few punchy climbs and 100% tarmac goodness. While short on distance, this course is still huge on views and excellent, twisting, roads.
Huge thanks to The Town of Gypsum for their generous support and helping us create these unique events. Thanks to their support, we’re able to offer onsite camping, complete with showers and bathrooms.
