Hi
After 4 weeks I'm a bit puzzled with fenix training load and ET.
Today I did a 30 min HIIT exercise (zone 4 and 5) and fenix rise 100 points in training load however sporttracks mobi rise 2 and TSS 0.
In fact, a 3 hour bike ride (Zone 3 and sometimes zone 4) gave me and aerobic ET of 3.1 and today 30 min HIIT gave me a 3.4.
So it seems that Fenix training load and aerobic ET is not the same as the classic training load, since a HIIT exercise has a greater impact than a long smooth bike ride. Does anybody have an insight about this or a white paper that compares both approaches?
Thanks
