I've been having trouble figuring out what to eat before running, so I thought I'd ask all you wise folks what y'all do....

I usually run first thing in the morning, and I don't usually feel like eating at that hour. I'm fine going 3 or so miles on only a cup of coffee, but if I'm going much further than that I do need to eat first. I've tried a wide range of nibbles, from pretzels to half a peanut-butter sandwich (and that really didn't agree with me!). I've done best on a couple home-made peanut butter cookies (but making cookies is a pain and I don't do it often). Any other suggestions? (I don't/won't do energy bars or other packaged, processed foods, BTW, both for reasons of cost and principle too)...

Thanks!
Sharon
