Notes
On the treadmill at work. Heart rate was totally screwy after about a mile and a half. It shows a max of 245, yet I felt fine. I'm beginning to suspect my heart rate monitor so will get another one to check it. Started out at 11:06 but went down to 10:40 fairly quickly and was at 9:40 by the end of the mile. Kept at 9:40 for 3.5 miles and then slowed it up. Was varying the pace to try to keep my average pace under 10:00 for the first time over 10k in many moons. Did do 3/4 of a lap at 8 in the penultimate lap, but didn't want to screw around too much because of the bizarre heart rate.
