How can I keep my hair from getting wrecked?!?

M'kay, so I have an award ceremony tonight at 6:00 PM. I put my hair in curlers last night, 'cause it looks cute when it's finished in the morning. I have a problem: I have Athletics 1st period, and our hair HAS to be in a ponytail, or else we end up getting a 0 for the day....how can I keep my curled hair in a ponytail without wrecking it?
