Congrats!! Non-scale victories are the best aren't they? I've taken up the Couch25K app on my phone and was able to jog a mile straight in under 12 minutes. Doesn't sound like much, I know, but for someone as unathletic and sedentary for me, that was a big milestone! Almost as nice a feeling as reaching ONEderland.
Keep up the good work and remember these NSVs when the scale plateaus.
