I'm very new to Primal eating, but have been dedicated to it for about a week now. I am a marathon runner, and have completed several fulls and halfs. I haven't eaten any processed carbs in the past week and am feeling fantastic! I have a half marathon coming up and I'm a little nervous about what to eat during my race. Usually for a half, I'll do one gel, but am a little scared that introducing it into my system might upset my stomach. My current thought is that I might replace my gu with a date or two, or maybe an ounce of raisins? They have the same carb count as the Gu plus loads of potassium. They don't have the sodium, but I do drink Nuun during any long run and am thinking it should be enough sodium to keep me going. Has anybody experimented with raisins or dates during long runs or races?

Thanks!
