Few weeks ago I bought Forerunner 935 to track my cycling activity. When I use Zwift all my training metrics (status, load, Vomax) are calculated correctly. Today I went outdoor with chest HR monitor but without power meter. After I finished my ride training effect was displayed but my training load was not changed. While analyzing training status graph in garmin connect I have noticed that optimal training load diapason (green one) was updated but not load itself. Is it bug or I will get load only with PM?
Both strava and TP requires only HR monitor to calculate fitness level / fatigue.
