Thought I was going to do a slow 6 this morning, but I looked at Hadd's schedule, and he calls for two runs a week that are a little longer and a little harder. So I decided to do one of those, 75 minutes at up to 145 AHR. It's 40, overcast, very little wind, perfect running weather. So I set out toward SHS, and realized, even pushing the pace and going uphill, the HR was barely above 130. So I pushed a little harder. Still in the low 130s, or lower. Turned downhill on Old Greenwood, even faster, still low HR. All the way home, same thing. So, running 55 seconds a mile faster than yesterday, with hills and everything thrown in, my heart rate was 8 bpm LOWER. That tells my just how much temperature affects me. That extra 25 degrees in the gym outweighed running faster and harder (up the hills). |
