Thanks all — really appreciate the thoughtful feedback here.
Just to clarify how Smart Coach is currently designed to function for running sessions:
For sessions in Zone 2 or lower → Athletica always prescribes by heart rate. HR is generally the most stable and appropriate internal load measure for low-intensity aerobic work.
For sessions above Zone 2 → Athletica uses external load (pace or power) if:
- You’ve indicated in your profile that your device supports run power, and
- You have a valid run power threshold.
In that case, Smart Coach will prescribe using power.
If no power threshold is available but you have a threshold pace, we’ll default to pace.
If neither is available or you’ve set a preference for HR, we’ll default to heart rate.
If those are set correctly but you’re not getting it appropriately, please report in with screenshots and we’ll see if this is a bug.
