Curious about what this whole gravel cycling thing is? The 27-mile mixed-surface route is a great way to find out! It starts and finishes on pavement, with a beautiful stretch of gravel through Castlewood Canyon State Park.

Sure a gravel bike is ideal for this route, but you’ll be perfectly fine on a mountain bike or a cyclocross bike. Just stay loose and have fun!

Start Time: 8:00 a.m. – 9:00 a.m.
Miles: 27
Elevation Gain: 1,700ft
Aid Station:
16 Mile

Sag wagons will rove the course with additional water and supplies, while providing roadside assistance to those experiencing mechanical problems or those who become too fatigued to finish. Please be prepared however to handle your own flats and minor repairs.  Road Marshals, Colorado State Patrol and Rapid Response will be on hand to help make your ride safe and enjoyable.
