I recently took up running. It lasted a couple of weeks with surprising and encouraging results. I fell off the wagon but intend to get back on any day now. I wanted to pass on this link a friend recommended. It's a very comprehensive site on running and has a great section for new runners. One thing they say is people shouldn't run every day, even seasoned runners. Maybe it'd be fine for you but I thought I'd pass that on.

Ok, I feel inspired. Maybe tomorrow?
