I run 1/2 marathons too! Getting ready for one coming up in Lincoln (sounds like you're familiar with the place.) I usually eat at least a granola bar before I run or a handful of cheerios. I also am really careful not to do more than one long distance run a week (generally burn through over 800 calories on one of those long runs). It's tough trying to balance fitness with CD, but it can be done. I work closely with a trainer, a nutritionist, and my GI doc to make sure I'm being healthy and safe. They advised me to use those gel packs while running... Gatorade and a bunch of other brands are out there... basically it's a gel shot of sugar and electrolytes... tastes aweful, but helps when you "don't have the stomach to carbo load" ahead of time... they also come in desolvable strips and jelly beans too... you can get em at practically any sporting goods store
