    Have you seen improvements in pace? This metric seems to primarily be based on speed and HR. If you have not been making speed increases, or if you have increased speed but so did your HR, your VO2 max will not move. Knowing your Max HR is important and has an effect on this metric so if you do not know it, I recommend getting or using a HR strap and finding out what it is. Other things can have an effect as well, if you have caffeine before your run it will increase your HR and it will decrease the calculated VO2 max. If you run first thing in the morning one day (when your HR is naturally lower), then in the afternoon/evening the next, it will see this as a decrease in performance. The weather has an effect on your HR and can change the watches calculated VO2 max as well.

    Personally I only like to use the Run app for VO2 calculations in the mornings, caffeine free, on days that are not recovery days, running on a flat terrain or track. All other runs I know will have increased HR or decreased speed and I use the Trail run app with VO2 turned off. The best thing would be to have your VO2 max tested in a lab, which I have not done yet either.

    i am on 5 zone in running. up on 170 beat

    V02MAX calculation needs different Data and Not Just Zone 5 running. Zone 5 is an all Out effort, so "Basic Data" for the watch is Missing

    Do some slower Runs and Not Just all Out. Everything with max effort is Not useful

    That is very high for an every day run, especially if that is all you run. Most of my runs are 2.8-3.3 avg HR between 145-155. If I go hard I might have a 4.0+ but I have yet to get near a 5, which I would expect would be for a race. (I have not raced since having this metric) Typically when you are going all out (near max) you are increasing your heart rate more and more for minimal speed gains which will be interpreted negatively on the watch. Also. running that hard regularly or every time can have detrimental effects on your progress. 

    You can look up your own plan online, try the 80/20 rule (80% easy, 20% hard), or even try following the garmin workout suggestions. Easy runs would be getting runs at a heart rate below 140-150 (this depends from person to person and will take some work on your end).

    My guess is if you are able to do a 5.0 effort regularly that it is your cardio that is lagging behind your muscle strength at the moment because if your legs were dying you would'nt be able to run fast enough to keep your HR that high on the next run.

    In the first post he mentions 7km so maybe he is talking about 5.50min/km

    To clarify, when i said 2.8-3.3 I meant training effect. That usually gets me 7-8 minutes per mile. I thought him running a training effect of 5 for every workout is too much.
