Im running an APAC Forerunner 255M with the 16.19 firmware.
Im using %LTHR to set my zones.
Previously to this week ive done base runs in zone 2 and they've been logged as base. No problem.
However yesterday i did a base run and it got classed as Tempo. Thought nothing of it, a blip and ignored it.
However today i followed the watch recommendation to the letter just to confirm things. Did a 30 minute "base" run at 151bpm (actual average was 149 for the run). At no point at all did the rate hit zone 3, not at all.
A very easy normal run.
However it has yet again been logged as "Tempo" and high aerobic load.
Any idea what could cause this as its going to start to play havoc with training focus if base is impossible for some reason.
Execution score 94%
Is Base/Tempo calculated on the user set zones and LTHR or something else? How is it deciding?
