Competition Day Starts 48 Hours Earlier

The pasta dinner the night before is folklore. The decisions that really affect performance are made much earlier.

If you only think about energy stores the night before, you're too late. Muscle glycogen fills over 24 to 48 hours, not over a single plate of pasta.

The two days before

From 48 hours before kickoff, three things matter: more carbohydrates than usual, familiar foods, and consistent hydration. Experiments are banned here.

The morning decides how your stomach feels

The last big meal comes three to four hours before the start; after that, only small snacks. If nerves kill your appetite, plan liquid alternatives instead of showing up hungry.

Takeaways.

  • Start carb loading 48 hours in advance
  • Never try anything new on competition day
  • Last big meal three to four hours before the start
