PJAMM DIFFICULTY INDEX (PDI)
NOW LIVE
The PJAMM Difficulty Index (PDI), our new system replacing FIETS, is now live! All climb rankings will now be based on PDI. We are in the process of updating many of our pages to reflect this change. During this transition period, you might notice notes on some pages indicating that the collection of climbs and page content is still based on FIETS. To learn more about the PDI, the reasons behind this change, and how it compares to FIETS, check out our blog post.

By: Matthew Jewett, Director of Technology | PJAMM Cycling
