I've tried reviewing all the how to manuals and youtube videos but I can't find a straightforward way to setup a HR target run. My FR 945 is currently set to pace, and I'd like to know what HR zone I am during the workout instead of reviewing the data afterwards. With the recommendations being in HR instead of pace as well. I'm trying to work through some health problems so I want it to talk to me about my HR instead of how I'm under or over my pace. I feel like that should be possible?
