Heart Rate Zones in Beta 15.09

After the first run with the new beta my heart zones got modified. My previous run, not using the beta, had heart rate zones that were lower..

The zones are based on lactate threshold. Today, the lactate threshold looks like this.

On todays run (16 km trail run) my maximum heart rate was 157 bpm. Why did my heart rate zones get modified?

Happened to also have done a run with the new beta today and for me the zones are consistent with the previous firmware...

Autodetect max hr, ltrh and ftp are set to on... Zones are based on LTHR.

You should post this in the beta bug report forum

All those are on autodetect for me too. The sport zones (running) are set to be based on LTHR and default is based on max hr.

I have both the default as the running specific one set to LTHR, guess it's somewhere in there.

Used to have only the default set (I only run) because sport specific ones would mess things up in the past, only added the running one again a (short) while ago.

I'm gonna try setting both to LTHR. Will see on my next run. Still, it doesn't seem normal to me. Just curious if others are experiencing this. Could be a bug with beta.

No issues on my zones from yesterday (14.20) to today (15.09 beta)

Both Default and Sport zones set on LTHR and the zones are still based on max HR.

Seems to work after a reset of the zones now.
