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?
