About riding in Colorado
Colorado's roads climb from the Front Range plains to high mountain passes well above 10,000 feet. Altitude slows most riders noticeably, and summer afternoon thunderstorms are common in the mountains. The main riding season runs from late spring to early fall.
Estimated finish times
The route is about 27 miles. Here is the moving time at a steady average speed. It is a flat-ground baseline: climbing, wind, stops at aid stations and group riding all move the real number, so treat it as a starting range.
| Average speed | Moving time |
|---|---|
| 10 mph | 2h 42m |
| 12 mph | 2h 15m |
| 14 mph | 1h 56m |
| 16 mph | 1h 41m |
| 18 mph | 1h 30m |
Most recreational riders average 12–16 mph on rolling terrain in a group, and less on hilly routes.
