Since a couple of weeks (after one of the recent updates) almost every run I do ends up being a Tempo run or higher intensity. Regardless of my exercertion level. I have set my own heart rate zones based on a sport specific treadmill test with a doctor. I set up these zones almost a year ago, so this did not cause the change.
Even if I run my whole run in lower end of z2 I end up with a Tempo run (see the attached example). This really skews my training load, so it makes all training suggestions quite useless. I use a Fenix 6 Pro with a Garmin HRM chest band. So I expect accurate readings. I hope this issue gets fixed very soon.
