Kat - Good luck! I see that you play hockey, right? So yeah you'll be in decent shape I would think. I am not good at the running thing though, myself, and never have been. I played soccer in high school and that was about it, but still hated the running (not in the games, but just distance running). I'm starting slowly to get into it!!
Dona - Congrats on the 10,000 steps! I have a pedometer but it needs a battery. I'm curious to know how much I walk when I work, just to see (since I don't do exercise on work days usually)
Belle - You should do this race! I think it would be good for you. Keep trying on the water, but yeah, of course you won't ONLY drink water!
kt_mom - Don't get discouraged. It has to be water weight. Water weight is the only thing that fluctuates that much. As you pointed out (I do this too, though) you should only weight yourself one day a week! You are meeting your goals, do not get down, it's only a temporary gain!

As for me, yesterday everything went to crap it seemed. It was warm but it rained like crazy so I couldn't do my walk, couldn't get a lot of things I wanted to get done, done, actually. Then I was watching the Food Network (DO NOT WATCH THE FOOD NETWORK!!!!!) and Bobby Flay was having a chocolate throwdown and I made a chocolate cake.

I always watch the food network and then want to be a gourmet chef all of a sudden and have to make something from the ingredients I have...soooo....yeah. I only had a small slice but a step backwards...I never let it get me down, but for full disclosure I'm admitting it. I'll take my walk today though.
