I also "hydrate" the day before with a Gatorade. I take Valerian Root the night before a morning race to help me sleep. While DH would like to be with me beforehand, I like being alone and since races are usually close to me, I drive solo to mentally prepare. I ALWAYS listen to the theme song to the movie S.W. A.T. the one that references Samuel L. Jackson - perhaps cheesy, but I listen to that before every race, softball game, interview, whatever. Everyone should have a "theme song"
