5. THE NIGHT BEFORE THE RACE
Night Before: Don't stuff yourself
Dinner should be relatively small but carb-heavy. Eat on the
early side so you have lots of time to digest.
"You want to wake up race day hungry—not full from the
night before“.
This is not the time to experiment – keep everything the
same as you are accustomed to.
