I recently disabled by Garmin Connect with Strava so I can get the Xert report on my Strava. Data goes to Xert first then sync to Strava. I see some activities are not being synced though like Cold Plunge and a Core profile I created on my watch. Walk , Run, Bike all seem to be syncing fine. Any ideas why that might be. These activities are in my Garmin connect but not showing on Xert or Strava.
For what it’s worth, I don’t think you’re missing any special analysis from those. I’m not certain how much those activities would directly contribute to cycling-specific fitness. I’m not saying they’re not beneficial activities, but Xert won’t offer much in terms of special analysis for them.
