The Death Race, the diabolical creation of veteran adventure racers Joe De Sena and Andy Weinberg, prides itself on messing with competitors' minds. It is, De Sena says, more "obstacle race" than adventure race. Entrants are not provided food or water. They are not told exactly when the race will start, when it will end, how long it will last or what their tasks will be. They know only that they will be so physically and mentally exhausted that just a small percentage will even finish.
