Well... two weeks in, I've walked 13 times, averaging a mile a walk, with my longest walk at 2.25 miles... that was about a half-hour ago. Holy crap that hurt. A lap around the block is .75 miles, and the goal is to be able to eventually jog four laps (3 miles) without stopping. Since I can currently jog about 30 seconds at a stretch, you can see how that is a long-term goal. Right now, I'm trying to build up to walking the whole distance, and once a week or so I'm walking/jogging a single mile as fast as I can.
I hate every goddamned second of it.
Everything hurts. I ache from my head to my toes. My tummy hurts. My butt hurts.
