I've struggled with my weight and eating disorders for a really long time.  I've gone through periods of being really active and fit, and periods of being really inactive and unfit.  I'm currently somewhere in between the two and am working to get back to my fit and healthier days.  I'm a runner.  I've run 5 marathons and lots of half marathons.  I had a close friend who used to be my running partner, but she's moved away so we don't run together anymore.  Not having her support has made me very aware of how much it helps to have someone to exercise with.  Exercising with her never seemed like exercising, it was just a good way to hang out with a friend.
