I've been a runner since I was in college. I can't do it as much as I used to because of the Crohn's and it causing "accidents." But, I never notice feeling bad/sick afterward. Are there any energy bars that you can eat? Probably not... What about a Gluten Free nutrition drink to pack in some calories?
Good for you for training! I am so impressed and hope to hear about your race!
