Zwift Climbing Difficulty

There are a number of climbs in Zwift, but I couldn’t find an ordered list of climbs ranked by climbing category. So I pulled all the info I could find together into this page.

Zwift’s “Trainer Difficulty” Setting

Before going further I should state that this is not about how to change the Trainer Difficulty setting. When using a smart trainer, Zwift gives the rider the ability to make the virtual hills and mountains seem more or less realistic to the actual grade. I personally like to set this setting to maximum, but you may not.

Zwift Hills / Mountains By Map and Climb Category

I have taken the climb category information from Veloviewer and Strava for each climb. I have listed all the active KOM / QOM leaderboard climbs that I am currently aware of. If I have missed any, please do leave a comment and let me know.

I have also listed any “unofficial” (non KOM / QOM) climbs that are significantly challenging.

For quick reference climb categories are determined by the length of the climb in metres, multiplied by the grade of the climb. This gives:

  • Cat 4 climb: 8000
  • Cat 3 climb: 16000
  • Cat 2 climb: 32000
  • Cat 1 climb: 64000
  • HC (Hors Categorie) climb: 80000

This information is taken from Strava support

Here we go, from hardest to “easiest” climb, on each map that Zwift has to offer:
