This morning I went to the track and did 1 warm up mile in 8:00 and then 3 miles in 6:40 with 2 minutes rest after each mile. I was going to do 2 warm down miles in 8:00 but ran out of time. My run back home was probably a mile. It was cooler but deceptively humid. My heart rate as up to 150 after the third mile in 6:40.
