Still no VO2MAX after a month

I now have the 945 for a month, and till this moment it did not once ''calculate' my Vo2Max (using the watch leds not an external heart rate band).

I understand it can take up to 4 weeks... I have been running 2-3 times a week, which includes runs at more then 70% of my max heart rate for at least 10 min. (as Garmin states is needed).

Do you have the same problem ?; and did you find a way to get it working... as all other nice new features of the 945 are based upon the Vo2Max value!

Are your runs indoor? It requires gps + HR to the best of my knowledge ;)

Yes, only outdoor runs... with the OHR sensor in the watch.

Using the Trail Running app maybe?

Make sure you are using the regular "Run" activity. Some of the other activity profiles are purposely limited from calculating VO2Max

Yes, useing the normal run activity....

If I remember well, it might need the HRM strap because of the much more accurate HRV measurements (al least it is like that on other devices)

It works with the OHR sensor and with three runs a week. After two weeks there is enough data for the V02max calculations.

Possibly related to my problem of not seeing the 7-Day Load: https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-945/165597/gcm-7-day-load-not-displaying-no-data-available

Did you previously (before your 945) own a Garmin device that would have "unlocked" the Vo2max feature for you? Do you have a 7-Day Load showing or not?

Before I had a Fenix 3HR which measured vox2max... and about every run i got a performance indication.

Now with the 945 i do not get vox2max, no performance indication, no 7 day load, etc ... guess it needs at last 1x a vox2max calculated to be able to get alle those other features/values.

I also did a run Yesterday... still no VO2max
