About the post below on training and heartrate...
It's right on. I kept my HR no higher than mid 160s and was able to run 9 min straight and 19 min total. I don't feel quite as fab as I did when I ran faster, but I was able to run longer, and probably am less likely to hurt myself. So, right on there.
The HR monitor: Awesome. Love it. I got a Timex, it was about $50. Totally enlightening in my workout.
OK, bedtime. Just wanted to add that to my other posts below. Another thing: running to Dan Savage's podcasts is a totally different, engrossing way to work out. I heart Savage Love.
