How do you verify the weight loss?

For all official weigh-ins, you'll be prompted to submit your official starting weight. Our standard weigh-in process involves you submitting 2 photos: one of you standing on a scale in lightweight clothing (no shoes, hats, belts, watches, coats, or outerwear), and another of the scale’s readout with your weigh-in word written on a piece of paper.

What you'll need

  • A scale (preferably digital)
  • A digital camera or smartphone
  • A full-length mirror or someone to take your photo

I just steps on the scale, and boy did I get an unpleasant surprise. I stopped going to the gym the whole summer, and the eating has been out of control lately. Ok. Let’s start here. Here’s to dropping the weight. It’s a never ending circus, isn’t it? Franny, PLEASE provide that extra source of motivation!! Good luck to all!

Hi Anna! I know exactly how you feel! I have been training for the Golden Gate Half in Nov, but I went on a family vacation and ate way out of control. I had gained 5 lbs before, and then I gained 5 more lbs during my trip. I have run about 3x, about 1x a week. and have now missed about 3-4 weeks of training. 10 lbs makes such a big difference for me while running. I can really feel it! I am definitely looking forward to getting back on track! Good luck to us all!!! :blush:

Good luck Tisha! Lots of running to do!
