I get VO2 Max when I start the run on my phone. As a matter of habit I start the run from the phone because I found that it has been more liable. I would love to start from the watch but I still have some reliability concerns.

Does the music display on your watch instead of the Nike Run Club app stats when you start a run on your iPhone? (Assuming that’s what you use) Since installing iOS 11 & Watch OS 4, once I glance down I just get a music overlay of what’s playing.
 
Does anyone have a link to how this is calculated without any understanding of oxygen transfer and utilization?
 
In a nutshell it is the maximum oxygen your body can consume in ml per minute per kg of mass.
yes, I know what it is, but in general one has to actually measure oxygen in order to derive that metric.

Read the white paper. They've got some pretty ingenious math that works out to be accurate to the traditional readings within maybe less than 5 percent if I remember it right.
 
Did my first run with the watch today and V02 measured 48.5 which is on par with the 48 I was up to with my Garmin over the last 2 years. Seems to be spot on.

It is an estimate unless you buy the optional BlueTooth accessory (batteries not included).:D

Where do I find the VO2 Max? I use my watch when I run or do elliptical everyday. I also use a HL10 Polar hear strap with their app as well. I see no VO2 MAx anywhere in my Health App. I had a S2 and now a S3 watch.

Thanks
 
Garmin's estimate of my Vo2 hasn't been even remotely accurate compared to the proper tests I've done over the years. Interested to see how the AW numbers compare. Do you have to use the built in workout apps for this to calculate?
 
So what are you all going to do with this estimate of VO2max?

It is fun to know I guess.

It’s only available on the health app on the phone

Has Garmin over or under estimated your V02? Just curious.

NRC has been inconsistent. I was getting just the NRC screen for about 4-5 runs. Suddenly today it was showing the audio app that was playing instead. I then manually opened the NRC app and it stayed on throughout the run.
 
I wear a Polar H10 and when I look in the Health app under VO2Max I see no data. I’ve done at least 12 runs on watchOS 4

Are they at least 20min in length?

Maybe try without your chest strap?

And which app are you using to start your run? Apple Watch stock outdoor run? NRC? Something else?

Based on the research data and process that is used to produce this result, it seems that one has to be quite consistent with their speed and distance-and a significant amount of distance and constancy of speed, in order to be able to divine from pace and heart rate some reverse engineering of the VO2 Max result.

A two mile isn’t going to do it. I would also wager that even a 3 to 5 mile run, with some pauses or variance in pace is also not going to yield a very accurate result.
 
“If you want a high VO2 max, choose your parents carefully. One group of scientists concluded that heredity determines up to 50 percent of your endurance ability. Still, that leaves 50 percent that can be influenced by training. While an outrageous VO2 max isn't the only ticket to running greatness--Frank Shorter's and Alberto Salazar's maxes were in the low 70s--increasing it can boost your race times. A five-point jump, for example, can translate into a seven percent improvement, or 90 seconds for a 20-minute 5-K. And a moderately fit runner can increase VO2 max by as much as 25 percent. “https://www.runnersworld.com/race-training/how-to-improve-your-vo2-mazcom
 
9 of the 12 runs were at least 45 minutes long. Started with the stock workout app on the watch for all of them.

Yeah this may only be possible when HR is calculated from the Apple Watch. Since all of Apple testing would be with their own hardware, I bet the way VO2Max is calculated could be way off for other monitors. (also, it's only series 1 and up)
