You lot over the pond worry too much.
Go live in Belgium.
Short of that, it's pretty simple. Much easier then you think. Don't worry so much! Relax, enjoy the ride. Like the other guy said, Bananna's are the best bet. Forget sports bars. Get normal muesli bars. Keep some on you.
Water?
Take 1/3 more then you think you'll need.
Take small amount $$$
If it's really hot, or your riding for more then around 2.5-3hrs, 1 bidon of sports drink. Preferably with magnesium.
And FYI when the pro's need some quick fuel, a can of coke goes a long way.
