Getting slower -
12-23-2006, 06:55 PM
I've been running off and on for a few years, but several months ago I decided to train for a marathon. I've been running mostly on a treadmill, due to job constraints. I started out running at about 9:30 to 10:00 min miles but then, all of a sudden, I just couldn't keep up that pace anymore.
Any Advice?
