VO2 Max in Garmin Connect

Read about VO2 max here: https://support.garmin.com/en-GB/?faq=lWqSVlq3w76z5WoihLy5f8

• Running activity must be 10 minutes or longer in length
• Activity must be recorded outdoors with a GPS signal
• Heart rate data from either a built-in optical heart rate sensor or from a chest strap
• Heart rate must be elevated to at least 70% of your maximum heart rate for at least 10 minutes continuously

Check that you got at least 70% of your max heart rate for at least 10 minutes continuously. Maybe your max heart rate is set too high?

To exclude an issue with syncing data: do you see your activities in Connect? Does the 'training status' widget on the watch have a VO2Max for recent days, or not? 

Thank you for your extended answer. I have read it carefully.

Not too high. 

The activity was copied correctly to Garmin Connect and I see all data: GPS track, pulse and etc. 

But the statistic on Website’s page: Reports -> VO2 Max doesn’t update for months.

I see my running activity on June 13, 2021 in Garmin Connect.

There is VO2 Max on my watch - 49.

I guess VO2 Max from "all activities" (shown in your screen clipping) is the same as VO2 Max from "Running" (not shown in your screen clipping)? 

Any suspicious heart rate settings under "Devices and Synchronisation" - "<your device>" - "User Settings"?

It looks as if not all information is synced to Connect. Can you sync via Express?

In your watch setttings, physiological metrics> max HR, is it on? Try turning it off.

And in user profile>heart rate>resting heart rate, is it set to average or custom when you select it? Use set average.

And is performance condition set to on? If yes try to turn it off>sync>on>sync. This might be important because from my troubleshooting, the vo2max will always calculate when performance condition notification pop-up while you run. If it didn't pop-up then the vo2max wouldn't calculate.

And for troubleshooting I always reset and delete data on my watch to remove variable. I have done a lot of troubleshooting and this method what fixed mine. 

I had an issue where my vo2 max won't calculate and have been troubleshooting for over 3 months and finally fixed it with this. 

And for troubleshooting I always reset and delete data on my watch to remove variable. I have done a lot of troubleshooting and this method what fixed mine. 

I noticed whenever auto max hr is on, my rhr will always reset to custom after a sync. And I also noticed whenever I run with rhr set to average without syncing to the phone, my vo2 max was calculated. And after syncing to the phone, rhr was set to custom and vo2max wouldn't calculate.

This might be an isolated bug because not that many asked this question, but there is always someone that asked and the answer is that they must've not meet the criteria for vo2max to calculate and you must've been doing something wrong eventhough you are within the criteria. I was also in this situation and got frustrated whenever this answer is mentioned eventhough I am following the criteria. I asked several people and they are mostly gave up or offered a replacement from garmin. I've sent tickets to garmin and the still have no idea what caused this. 

I am on APAC version, but someone with ROW version did ask the same question and said my method worked on the next day, but stopped the day after and said he/she is still working on it for a few more runs but haven't heard since.

I asked several people and they are mostly gave up or offered a replacement from garmin. I've sent tickets to garmin and the still have no idea what caused this. I hope this will help.

This helped me. Now VO2max and Training Status works too. Thanks.
