From couch guy to marathon runner, 18 months

I was 280 pounds, worked a desk job, and hadn't run since high school. My doctor basically told me I was headed toward a heart attack if I didn't change something. Started running 2 miles a day, cut out a lot of junk, and just kept showing up. Ran my first 5k at 6 months, first half marathon at a year, and finished my first full marathon last month. I miss some of the lazy weekends but I don't miss how I felt before. My knees hurt now instead of my chest, so I'll take that trade.
