This morning was the first time I tried to follow the suggested workout.
To complete a base run at 5:20 min/km for 54 min. Expected aerobic load = 2.4 (if I recall correctly).
I know this is not a correct base pace for me. But I just gave a try and here are my training stats:
Average HR = 165 (zone 3, my max HR = 199)
Aerobic load = 4.2
Exercise load = 198
Benefit = Tempo
My question is, despite countless of recorded activities, why does Garmin not learn about my fitness correctly?
Just a little bit of background.
My PB of 10 km is 42 min recorded during my peak fitness. So when I use the following calculator, the website suggested me to do easy run (base) at 5:10 min/km.

So basically, Garmin has used the same formula or algorithm as above to calculate my base run. Note my current fitness is slightly lower than peak (8 months back).
