To keep things as simple as possible, I have linked my Zwift with Garmin Connect so that I don’t have to record cycling activities on the watch anymore. Now, all I have to do is use zwift and the activity will auto go over to connect. As per DCRainmakers post: https ://www.dcrainmaker.com/2021/06/garmin-training-status-now-includes-zwift-trainerroad-the-sufferfest-and-tacx-app-workouts.html
However, I am unsure if doing this will allow my Forerunner 965 to update my VO2, Lactate Threshold, FTP, Max HR etc?
probably not since that info is stored on the garmin unit itself, but what you can do is record your zwift activity on your watch simultaneously with zwift and that should work. unfortunately it means you will have to record the activity on your watch one way or another
I don’t have a watch that displays it, so I’m not sure.
But according to the Garmin site, one of the things it’s based on is Acute Training Load. Judging by an activity I checked that was on Zwift alone, I did get a training load score, so I’d guess it’ll work.
Zwift rides do update the metrics that are available on my Forerunner 935, and I can see a few more on Garmin Connect itself. Garmin doesn’t seem to care about Zwift FTP tests, so you might have to start one on your Forerunner while you’re riding on a reasonably flat course in Zwift.
I don’t train seriously myself, so I can’t tell if Zwift rides give a misleading picture on Garmin in terms of training effort (I use Today’s Plan for those metrics).
One word of caution: Zwift distances/times/elevation gain do not count toward Garmin Connect challenges.
Garmin is my “fitness social” platform of choice so despite the physiological metrics now syncing from Zwift, I’ve gone back to unlinking the two systems and double-logging, editing the Garmin entry with the correct Zwift distance and elevation.
