You can see it below on our calendar. That when you convert workouts it converts them to colored zones. We might change the colors… It’s a long discussion why I think this is good for HR but not for power zones… but we will leave that out.
It sends zones and I believe the way it will work in Garmin is that the Garmin zones will determine those ranges. I have not tested this yet in Garmin. so changing your zones in Garmin will fix this. How a person’s power converts to heart rate is very individual and so It’s not a simple conversion that is the same for everyone. So you don’t really have to set our zones other than what visually it will display and so that it matches up with what’s in Garmin.
