K Pax-ian running

Hi MLCM, shame about the shin splints. You could try jogging through them, and taking it easy on the hills. Regarding your heart rate, I agree that it's a bit soul destroying trying to keep within that range. Really though, 80% is still aerobic, at the top end of the scale but still aerobic. Do you set the zones you want to work in? I have found that when I set the excercise set to between 60 & 65% it's hard to keep within the zone. If, however, I just use the basic set and run at a very comfortable pace, then it's easier. God knows why. How do you know your max? My hrm says mine is 180BPM, I was running an average of 181 on Sunday and have seen my HR as high as 196 so what the HRM says is not always accurate - on the test side - the recording of heart rate yes.
