Laps Around the Track - talking about heart rate monitor, low zone, zone 3, 30 minutes

Hey, it's Brewster again. Just finished the first leg of my day. Just the 2mi one up run and I'm paying close attention to my heart rate monitor. I'm still doing the 2 minute run one minute walk and as I'm walking my heart rate is averaging around 170 and when I'm running they get up to 195 so you know I'm not sure if that's a good thing or a bad thing. I know I'm running, I'm on a run in that zone 4 area and then walk just walked a minute so I wanna average the low zone for high zone 3 throughout the run and it looks like that's what I'm gonna be doing for this run so 2mi complete in about 24 minutes. It's about 30 minutes now to the start. I think I should have timed this a little better so.
