Notes
Wore new FR235 today, but not in "run" mode. It still reports HR, which is great. Wore it to bed, so my resting HR numbers will probably be lower from now on (it showed 42 bpm for low). On TM, 6.4 mph at 1% incline kept HR around 130. 6.5 or 2% caused it to go above 135, so I'll try to stick to 6.4/1% until I'm fully recovered.
