NY Times-Why Joggers Labor and Olympians Fly

Here's a link that my daughter, bless her miserable little marathoner's heart, sent to her old, slow dad.

Is it coincidence that my daughter sent me this on the same day that MadCow posts his, "When did you realize.." question.  I think not.   It is a conspiracy to get me to run some intervals.   Won't work.  I am slow and proud.

On this same topic, a young friend of mine, Jeff Boyd, who is a pretty good triathlete (usually finishes second in Tri-the-Parks series sprints), did my Norris Lake Triathlon Course at my lake house a couple of years ago.  He borrowed my Polar S610 heart rate monitor so I have a record of his splits and heart rate.  At almost exactly the same heart rate as me, he finished in exactly half the time.  At least I know that in my chest beats the heart of a champion.  Too bad its connected to the legs of a sloth.
