Variance between zwift speed and Garmin

Hi anyone have a fix on how i get my garmin app to agree with the zwift pace.
The variance is actually massive … a 125km ride records below 90kms on
my garmin

No correlation between Zwift and IRL speed. You can get close on flat routes (the Desert areas) but once you hit the hills it can deviate…as you have seen.

Ever since I turned on the “ERG mode speed simulation” in the Wahoo app, I noticed that the distance that my Garmin records is much closer to what Zwift shows. They can never be the same due to elevation profile, drafting, surface etc. but it is much closer than it used to be.

Try if that improves the situation for you as well. As the name says, this is only applicable when in ERG mode (workouts).
