Why do I run instead of lifting weights, a clearly superior activity?  It's 
an experiment based on both Phinney's research as well to see if I, at 41 
years old, can get back below 7 minutes a mile in what used to be my event: 
the 5K.

Good luck Jim,
Keep us posted on this one and when you're finished see how you fare with a 
circuit trial.  Oliva
