I run because it's the only thing that I feel really helps me lose/maintain weight as far as exercise. The problem is I have not great knees and feet so I can't go as much as I want and sometimes it knocks me out for a while before I pick it back up.
Currently I'm up to 3-4 times a week, getting 3-4 miles each time. Usually I shoot for 2 of the runs to be more "instense" and 1 to be an easy job and if I do a 4th it's somewhere inbetween. I'll probably never get to where I run marathons or even half marathons but maybe a 5 or 10K .
