A lot of it for me, depends on how far I'm traveling for the performance. Often, the day before is spent traveling to the destination, and so my last run through has to be two days before. Day of, I never do a full run through, i want to conserve my energy. But I also tend to do a lot of strength tricks in my routines. Hopefully there will be time to warm up and practice on the poles the morning of the performance, if so, I test out the poles, with some of my fav combos, or some of my harder tricks from the routine. Get a sense for the floor and how my floor work will go in an unfamiliar space.
I have trouble eating when I'm anxious or excited, so I force myself to eat small snacks almost every hour, on a schedule. Easy to eat things, like protein bars or fruit. Two hours before I drink a full 16 oz of water. That allows for proper hydration, and time to pee out the excess. One hour before I start really warming up and stretching. One layer of tite grip about 45 min to an hour before going on, about 15-20 min before going on, and dry hands right before they call my name. I'll sit in an easy (for me) over split for a few minutes right up until I go on, to make sure my splits are all the way there.
