I ran in excess of 32 miles a week for several years and the only side effect I had from it was blisters.

I started running again a few years ago after a 5 year hiatus from any regular physical activity. I logged my Time, Avg/Max HR, and Calories burned for each run and there really wasn't much of a change in metrics over the 3 year period I tracked them. My heart rate was surprisingly stable and run times reduced gradually but only about a minute a year.
Maybe if I was incredibly unhealthy but I generally eat well and at my worst I've only been 20-30lbs over weight. I know that sounds like a lot but I'm 6'5" and my "ideal" body weight is 190lbs which is kind of ridiculous.
However, once I stopped eating a few things that continually gave me sinus problems I didn't even realize I had, I did feel less depressed :)
Then I stopped eating wheat and I stopped feeling like someone punched me in the front side of the head. It was truly bizarre. I had no idea.
