What's the best form to get carbohydrates in prior to running, and how much should one take in, and how long before the workout? I know I had an easier time running when I had some breaded and fried chicken (not sure how many carbs in the breading) one day before a run, but I had some chocolate before my run today (8g carbs) and it didn't help nearly as much. Is it the amount of carbs, or is it the type of carbs, or possibly a combination of both? I'm currently doing interval running during which I burn approximately ~1000 calories (+/- 150 depending on the day and workout).
I've been on a low-carb diet, and I'm comfortable with breaking that if I need to in order to have energy for running, I just don't want to overdo it and take in more than is required for energy for my run, since I still have some weight to lose.
