A little clarification . . .
As I said in my first post about running that 2 miler at a 6:48 pace with a HR of 148, I didn't start checking my pulse until the moment I finished, so my heart rate may have slowed some during the 30 seconds I checked it (then I multiplied by 2). The temperature was pristine and the humidity level was very low that day. I've since purchased the TOMTOM cardio runner, a great great tool (no strap, the HRM is built into the wrist unit, see my review on it in the product review forum). Southern Illinois is often as humid as Louisiana, very very humid. When the humidity is high I can't go much faster than a 9:30-10:00 minute mile without it going over 150BPM. When the temp is cooler and the humidity is low it my HR seems to hang in the lower to mid 150s while I'm moving at a sub 7 minute mile pace. I've been a runner since I was in junior high, though I have run in pain for the last +10 years. Not so much now!!!! I figure that helps my HR some. Plus I run in merino wool products which have superior thermoregulatory properties (even better than not wearing a shirt) and are very light weight. I figure that, to a small degree, helps too. My resting rate is 48-55 (see my article on heart rate in the blogs section).
