Before you go

Colorado afternoons build thunderstorms fast, so start early and be off high, exposed terrain by early afternoon. Ride within your limits at altitude, yield to hikers and uphill traffic, and pack the essentials — water, layers, tube/pump, and snacks. New to the elevation? Read up on the altitude first, and see the full Colorado mountain biking guide, and gear up with our mountain bike gear guide.
