VO₂max / Fitness Level not working
- 
 I made 1 run, 2 walks but VO₂max / Fitness Level widget is still not activated, and just show text with description about calibration! What in the name of the god is needed, should I run marathon to get this activated?  
  
- 
 The calculation has some boundary conditions: - proper GPS reception
- long enough activity
- some minimum or varying effort
 For me it is working well outdoors with a 30min run under open sky being in HR zones 1-5. can you share your running activity here on in PM? walking will probably not have raised your HR enough…

 @Jasmin-Klipic Run 10 km outdoors “fast” a you will get it, I think yours 3.2 km in 34 min is not fast enough.

 I got my vo2max estimation after my first run(3km about11mins) with s9pp. It looks like you got a configuration issue

 @zhang965 Well, you did the same distance in one third of the time… I guess his HR was too low for all the activity time.

 @zhang965 Mee too (in fact an OHR arm belt, Polar) but in essence is the same.

 @Egika Additionally/alternatively, he might have had a GPS loss. When the watch doesn’t have any older VO2 value to use, if you at any point during the workout lose GPS (start when it’s not found; start when it’s just found and instable so maybe you lose it for a few seconds immediately after; go under a tunnel), the VO2 is not calculated.

 but minimum effort is not mentionned in the user guide

 @zhang965 this is why we have this forum with a lot of user experience in place

 but minimum effort is not mentionned in the user guideno, and it is mentioned in documentation “run or walk”…and I walked 5,5km/h, and this not slow at all, and had 105/110 bpm, but this is not enough, or the sh… does not work… well, how ever the watch goes today back to amazon 
- 
 I’m closing this thread to avoid duplicates as there are plenty of discussions about “vo2 calibration” and since the watch is being returned.
