Notes
50F 87%H 46DP, At the Collins High School Track. Had wanted to do 1 mile at each heart rate of 115, 120, 125, 130 and 132, but couldn't get my heart rate down below 125 -- too cold and windy. It seemed a lot colder than the 50 that is quoted at the halfway point. Maybe that is because the air was so damp. I'm going way too slow for these heart rates. I guess that is just loss of conditioning.
