This is an interesting article I came across on PowerBar.com. It is basically a commercial for PowerBar but some of the information might be usefull.
I recall some folks saying they were depleting thier carbs before the Buffalo Marathon. I definately bump my carbs up before a race or long run but have never tried deplete them in the days before a race.
Different things work for different people, but it is an interesting question and answer column.

Carbohydrate loading is not new. It dates back to the late 1960s, when Scandinavian scientists found that after several days of a low-carbohydrate diet, men in their study had low muscle glycogen stores and less endurance compared to when they consumed a moderate-carbohydrate diet. And when the men consumed a high-carbohydrate diet over several days, glycogen stores in the muscle became supersaturated, and endurance times were significantly extended. The scientific term for this loading of carbohydrate fuel into muscle is glycogen supercompensation, and these studies led to the classic seven-day model of carbohydrate loading ó itís a model youíll want to avoid.
