Just read one of the Yahoo! Health articles about good carbs/bad carbs, and here's the last paragraph:
Q: Should I ever carbo-load?
A: Consider it when you’re training competitively for a 90-plus-minute endurance event, says Roberta Anding, R.D., instructor at Baylor College of Medicine. “Carbs are exercising muscles’ preferred food,” she adds. But nix the prerace pasta bonanza: You can’t store that much extra glucose. Instead, up your carbs five days or so prior, to about 8 g per 2.2 pounds of body weight a day, and trim fat to avoid weight gain.
By that math, this is recommending I consume over 1,000g of carbs per day in the days leading up to my event. That's a kilogram. Or 2.2 lbs.
