220 miles to train for a half-marathon....

Yep, thats right. In 3 months of training for a half marathon (based on the Hal Higdon's Novice Half Marathon plan), I will have run a total of 220 miles. Sounds like quite a lot, doesn't it? Yet, that will only reduce my weight by 8 pounds (220 miles X 120 calories burned/mile, divided by 3500 calories). All of that effort and only 8 pounds of fat! Doesn't really seem right! And not only that, I will be hungrier, I'm sure....gotta keep my appetite in check when I start this training plan in early November!
