Tour de Tri 24hour Tri. Am I crazy to be thinking about doing this?

Is anyone here planning on doing this? http://www.brisbanetrisquad.com.au/tourdetri.phpt sounds like an exciting challenge but I think I will be biting off more than I can chew considering I have only done 2 enticer distance tri's so far. How the heck do you train for something like this???? I have enough trouble trying to stay awake to watch tv shows I like that they put on tv after 9 oclock. Maybe I wont watch those shows and Train late at night!?.
