Well you don't have to do it straight. you can press the start button and pause the game, then switch of the controller so no accident happens and a button is pressed and you resume the race while you are gone. switch off the tv but not the ps3. When you come back resume where you left it. And don't forget to pray all the time to whatever god you like that your ps3 doesn't crash or you get a blackout. (Like i did yesterday, i really got mad because my bob was already racing Tsukuba 9h for more than 8 1/2 hours and then there was a blackout)
