I bought the forerunner 965 a month ago, and it immediately gave me a VO2Max reading of 39 on my first walk on April 16 , and then updated it on my first run to 38 on April 21. Since then it has never shown another update, no matter what exercise I do, walk (I'm past 65, so walk's are allowed.), It updates my fitness age regularly to around 10+ years below my actual age, adjusting both up and down.
Since it's been about a month since last VO2Max update, and some readings require updates at least once a week, how can I trigger a new update? I think I meet all the requirements, duration, cadence, heart rate, etc. One possible exception is it doesn't want to recognize running vs walking detection, although in latest sessions, running time passes the 10 minute requirement, even though it insists I am walking for part of a 25 minute session, even when I am at least jogging for all of it.
