Wow, I don't know how you runners do it. I can't stand running. How many miles do you run per day on average?

I love to run, did Track and Field in High School! Right now I'm only running 3 miles till I build my stamina back up! What do you do for excersise?

I usually jog in the backyard, but not really running. I'm too fat to run.
