re: Official Running Log/Marathon Training Thread

I'm fat, and while working out has helped me lose fat and put on muscle, I'm still way heavier than I want to be. I'm slowly transitioning from taking long walks (walk 2 to 3 miles a day) to jogging. I have zero plans of ever becoming a runner, but I'd like to get to the point of a jogging a 5k with sub 9 minute miles not something that kills me.

I've been trying to walk/jog 12 minute miles and succeeded the past week on 2 miles or so of that a day.
