Colorado Bicycle Climbs

One of the great cycling experiences in the state of Colorado is climbing in the mountains.

We have a tremendous selection of canyons, passes, and mountains to ride up. Over the years my wife and I have been drawn to climb many of the passes and "classic climbs" in the state. We started in the San Juans climbing Coal Bank, Molas, and Red Mountian. Several years ago I came across a list compiled on paved passes and classic rides. I was amazed that we have done many of the rides on the list and have lots of great memories from those rides. This makes me wonder how many other cyclists and RMCC club members have climbed these passes. We have compiled a table with 80 climbs (paved passes and classic climbs).

  • Total Paved Passes: 46

  • Paved Passes over 10,000 ft elevation: 27

  • Classic Climbs: 15

  • Total Climbs (all types and directions): 80

If you have a climb in Colorado that is not on the list, please us me know.

The Team

Mike Prendergast -It was Mike's idea to create the Colorado Bicycle Climbs list. He wrote much of the text and collected the data for most of the climbs. 

Sam Fisher -Sam wrote all the code for the database and the php. Without him this project would not have gone far. 

Rita Braun -Rita's editorial insights helped make the data more useful to the end user. Rita gave guidance on the functional layout of pages, the descriptions that were used, and how the data is displayed.

Tim Dodge - Tim helped devise the ranking method used to help you judge the difficulty of each climb.
