Training status on My Day

How old is your last VO₂max value?

Monday 2/19/24

Could you post a screenshot of the page https://connect.garmin.com/modern/report/-1/all/last_four_weeks ?

(you can scale down the page to fit on the screen)

Well, the last VO₂max value is not from Feb 19th as you wrote, it is from 12th. That may be part of the problem, but there also seem to be a sudden drop of the Acute Training Load on 19th. That usually happens when the watch is reset, or perhaps due to some problems during a firmware update (if it happend on that date). 

I was on the bike hard on Monday, and pretty sure it was still working at that point. And I did get a firmware update Monday or Tuesday (don’t remember which)

You don't have any biking VO2 max values (unless they are the exact same value as the green ones). Biking VO2 max are blue. All your VO2 max values are green so they are from running/walking/all-day HR.

To get biking VO2 max values a power meter is required.

So….it has miraculously reappeared but this has happened to my recommended acute training load

There is no VO₂max value since Feb 12. Try to make a qualifying run triggering new VO₂max measuring. Also double check the Max HR value in Device Settings » User Profile. If it is set too high, you may have problems to get a new value.

Would think the 5 miler I did on Friday would work. It appears to have “lost” everything for 2 or 3 days of exercise
