Miles done on virtual rides are not counting toward my monthly challenges.
Only activities recorded with a Garmin device or app (Tacx) count towards badges and challenges. See thread - Garmin Connect Badges Not Being Awarded
Also - What Are Garmin Connect Badge Achievements?, under the section titled "I Was Not Awarded a Badge for an Activity or Challenge I Completed."
The activity recorded needs to be saved and uploaded directly to Garmin Connect and cannot come from a third-party app or website such as Zwift.
