Do you know why custom heart rate zones are not picked up in Connect post activity data? It seems to revert to %max HR? The post workout analysis therefore being incorrect.

Not sure if I understand what your issue is, but the heart rate zones shown in the activity reflects how the zones were set up at the time when that particular activity was recorded.

If you change your zones, it will only affect future activities, Connect will not go back and recalculate old activities.

No, the heart rate zones in the app post activity do not reflect how the zones were set up when the activity were recorded. 

Put another way.

I have set up the zones manually which are reflected on the watch and shown correctly in the app.  However post activity the heart rate zones are different and based on % of max...which is incorrect.

Okay, disregard my first comment then.

Which activity type are you using when this happens?

Outdoor run

I guess you are aware that it is possible to have different zone setups for different activity types? (General, run, bike, swim)

If you just want to use the general zones, make sure that none of the sport specific zones are enabled. (or vice versa)

Thanks.  I had read about different zones for different activities but can not see where to adjust those.

On the front page in the GCM app, tap on your device on top of the page, scroll to user settings, then pulse zones.

There you should see different tabs for the different sports.

In the user settings there is no pulse settings.  Only heart rate zones.  In heart rate zones there is no option for different activities.

What kind of device do you have?
