Keith Burgess-Jackson, J.D., Ph.D.

I had a good month, aerobically speaking. I ran 16 times, for a total of 33.1 miles. I also rode my bike four times. That's 20 aerobic activities in 31 days. As if this weren't enough, I played softball twice and walked Shelbie a zillion times. My resting heart rate this past Wednesday was 46. I weighed 155 pounds this morning, naked. It won't be long before the fall racing season begins. I'll be in the middle of the 50-54 age group this year. When you enter an age group, you have an advantage, since you're competing against people who are older than you are. In the year before you leave an age group, you have a disadvantage.
