Hi,
I trained on my tackx trainer this weekend for 4 hours, it was an endurance training in zone 2 so very easy and should be anaerobic training.
So I use a Forerunner 955 and a garmin strap heart rate monitor, the tackx trainer sensor is compatible with forerunner 955.
Avarage heartbeat is 127bpm. My training stamine/potential goes down from 80% tot 0% from minute 45 until minute 50 all of a sudden?
I trained 3h30 in zone 2, 30 minutes in zone 3 and I get a training effect of 5.0 aerobic and 4.2 anaerobic?? The exercise load was 1001... For a low intensity training.
I never had this before and am struggling to understand why?
