Hi all,
Just did this long run with mainly Z2 HR and then some low Z3 stuff. The watch has earlier given this as either base or tempo training, but now VO2? I know earlier FW been pretty messed up on this before, time again?


Your z4 goes to 177 up, but your LTHR is 171bpm. Is it not so, that z4 is <99%LTHR and z5>100%, say 171 and up?
My LTHR depends on my current training condition and the zones distribution is not always such precise. If i do a zones reset for my current condition it will be corrected. I've had a z5 set to a 108% of %LTHR - it was not funny It looks like Garmin does not adjust zones after auto-detecting new values.
