5.5 miles in 1:13:05 for an average pace of 13:17/mi and an average heart rate of 128bpm. Not my best day, to put it mildly. I did it all without a drop of sweat. I wore shorts, long sleeves, and gloves, but that was all the protection I had against the cold (28 degrees). I'm thinking that my heart worked overtime to warm my body, just like it works overtime to cool the body in the heat. The heart rate monitor was all over. Sometimes I'd see it jump 10 ticks without any notable pace change. |
