You have to push yourself and the car very hard for the entire race. The field is so deep and there are so many good teams, you can't afford to back off the pace too much (to save the car for the entire 24 hours). You have to be very smart in traffic. That one move you would make in a sprint race, you may have second thoughts about doing but for most part you have to go for it.
