Zone calculator

Is there a power and HR zone calculator based on FTP posted in the forum somewhere??

I am not aware of a basic calculator from TR. They do provide the data in a way, when you view a completed workout. You can see the Power Zones that are derived from your FTP in that workout.

And since they place HR down in the priorities, they don’t cover HR Zones

I share my Google Sheet that has two tabs of info for the main Coggan Zones and 3-zone for POL training, that includes Max HR & Threshold HR data in either modality.

Outside of that, there are numerous other options to be found on the web via search if those don’t suit your needs.


Here is another great resource for setting HR zones.

I’d recommend using lactate threshold HR as your driving factor as described here.
