i cant see my fitness-age in Garmin connect ,it was working yesterday.
Now its working again or not ? i went from 20 to 46 in 24 hours, weird?
Same thing happened to me today. I went from 20 to 41.5. I want to be 20 again!
There is a thread about it here: forums.garmin.com/.../achievable-fitness-age
It is probably the new fitness age function you got now. In the old one the lowest age was 20 years. The new one is [your age] minus 9 years as lowest.
