Without giving too much info (basic info is one thing but contest info is another) you should be so carb depleted the day before the show that the carbs you eat would be sucked up by the muscles and stored as glycogen. Typically it would take almost 72 hours of consuming more than double your maintenance level of carbs in order for you to spill over if you have depleted properly.

Hopefully this helps Debbie.
