Thanks for the replies!
MBN - thanks for telling me this, although I admit I'm kind of disappointed. A huge part of me was hoping that weight loss would just come on its own with the amount of running I'm doing. But it looks like this journey will not be over that easily! The amount of running you're doing is impressive, congrats! I'm pretty excited for my first half marathon
Kim - from what I've seen in the 1000 miles running thread you run a lot, I'm surprised you're also stuck in a plateau. Have you ever tried limiting yourself in carbs at certain times of the day? This was suggested to me but I wouldn't want it to slow me down.
