My Apple Watch series 8 has stopped tracking my VO2 max. I’ve checked that the watch is the data source, it’s still reading my heart rate and I’m doing over 20 minutes of walking/running 3 or 4 times a week. I recently downloaded a couch to 5k app, could it be interfering? Everything else is tracking as normal and all other data in the health app is up to date.
Was a solution ever found? I have an Apple Watch 9. It was consistently tracking Vo2 max for runs >20 minutes. But now it’s not calculating at all. I followed all the tips in this thread without any success

It never resolved for me with any of these fixes.
My Apple Watch (Series 6) has been calculating VO2 max for almost 3 years with no issues.
One day it suddenly stopped calculating VO2 max. However, it can measure all parameters such as O2 level, heart rate, etc.
I have tried everything but still no luck. I was hoping the next software update would fix the issue, but I just updated both iOS and WatchOS and it still doesn't calculate VO2. Very strange.
Same with mine. Tried everything. I left my phone in my car. When I ran far from my car, the vo2 max, stride length, vertical oscillation, ground contact time
Not tracking. When ran near to my car and connected to iPhone it track until it disconnect.
This has been happening for over two years! I’ve switched to two new watches including a series 8 and it has never updated. I’ve tried disconnecting reconnecting reinstalling etc to
no avail.
has you issue been resolved?
The issue seems to be only for certain individuals, most of us get VO2 readings for outdoor walk or run. No other activity will generate VO2.
Ensure you have only the Apple workout app installed for now.
Check you have not turned off any permissions for HR in iPhone, Watch app, My Watch tab, Privacy and you have all your details in
iPhone, Watch app, My Watch tab, Health

Hello Paddersthebear,
Welcome to Apple Support Communities.
We understand that your VO2 Max is not tracked as expected. We are happy to help.
We recommend using the steps here to calibrate your Apple Watch: Calibrate your Apple Watch for improved Workout and Activity accuracy - Apple Support
"Check your settings
To make sure that your Apple Watch can get the information it needs, check these settings on your iPhone:
Calibrate your Apple Watch
.If you don't have time to finish the workout, you can complete 20 minutes over multiple outdoor Workout sessions. If you work out at different speeds, you should also calibrate for 20 minutes at each of the speeds that you walk or run.
Whenever you walk or run outside using the above steps, your Apple Watch continues to calibrate the accelerometer by learning your stride length at different speeds. Calibration can also improve the accuracy of your calorie calculations in the Workout app, and the calorie, distance, Move, and Exercise calculations in the Activity app. "
Here’s additional information tracking your cardio fitness: Track your cardio fitness levels - Apple Support
"How Apple Watch estimates your cardio fitness levels
Apple Watch Series 3 or later can record an estimate of your VO2 max using the heart and motion sensors during an Outdoor Walk, Outdoor Run, or Hiking workout in the Workout app. Apple Watch supports a VO2max range of 14-65 mL/kg/min that is validated for users 20 years or older.
To estimate your cardio fitness level, your Apple Watch also takes into account your:
It can take at least 24 hours of wearing your Apple Watch, followed by several Outdoor Walk, Outdoor Run, or Hiking workouts* and passive measurements with your Apple Watch before you receive an initial estimate.
If the Health app detects that your previous cardio fitness estimates could be more accurate, you'll have the option to update your data. In Cardio Fitness, tap Update under Update Your Data. After you update, the Cardio Fitness Data Updated notification shows you the results of the update and how your estimates changed."
Let us know if you have further questions.
Take care.
Same problem i m facing… done everything but no resolution…😔
Me too!
You can still try the next one.
Put watch in airplane mode during 20 min. Outdoor Walk or Outdoor Run. The vo2max value will be displayed / registered.
It is not a solution, but a workaround.
it wont record V02 max when my iphone is not with me while running.
any solution to this?
