I loved running when my weight bottomed out(168 for a 5'10" frame). As a former fat kid who never ran a mile and always found a health reason to escape PE class it was amazing. It didn't last long though. I met my wife and started gaining weight, and soon I was back to where running hurt like hell.

Now I hike, and I love that. I don't think I'll ever lose enough muscle and fat to get down to where running feels good again.
