How do they assign difficulty levels?

I tried to determine threshold that lies within their Difficulty Levels:

This may be wrong, but I think it boils down to this:

  • Achievable = Below or Equal to your current Progression Level
  • Productive = 0.1 to 1.0 higher than your current Progression Level
  • Stretch = 1.1 to 2.5 higher than your current Progression Level
  • Breakthrough = 2.6 to 4.5 higher than your current Progression Level
  • Not Recommended = 4.6 or more higher than your current Progression Level

This is just a “simple math” issue related to assigning the DL Labels. The reality of actual difficulty lies within how accurate your actual PL is for any Zone. It’s more likely for this to be off for new riders with limited TR history in their PL, as well as people hitting Zones that are not up to date. This could be from focus on particular zones while not hitting others, or returning from breaks in training.
