Agree. There is no right answer. You have to play around and figure out what works for you. When I'm doing a long training run or a marathon, I eat something (usually a half a banana and a half of a bagel with peanut butter) about an hour before I head out. I'm usually feeling like I need to eat again somewhere around mile 21. The gels work. But for me, they aren't any better than a couple of bites of banana or a fig neuton.
To stay hydrated, I drink mostly water. The only time I add a sports drink is if it's really hot or I'm running more than 12 miles. Even then, I alternate between water and sports drink.
As far as having to go to the bathroom - We've all heard of the runners trots. It it hits, it hits. There isn't much you can do other than adjust your diet.
