Today I did a hard workout which gave me a focus of Threshold and 54 hours of recovery. Immediately afterwards I started a new activity for which I ran 3km in zone 1 (I was monitoring it the whole time). Now normally that would give me a load focus of “Recovery” and not impact recovery time significantly. However it gave me a focus of “Tempo” and a recovery time of 65 hours. On top of that, when I see the activity data on the watch after saving it the focus is indeed Recovery, with the same Aerobic impact but the recovery time hasn’t changed.
Not sure how to reproduce this, but I assume if Garmin wants to debug there is a way to send diagnostics, which I am happy to do.
