quitting isn't an option

I've had several moms agree that there are similarities between training for a 1/2 marathon and training for delivery. However, my mom pointed out that even after all of your training if you get to mile 11 out of 13 and you can't go any further there will be a sag wagon to haul you to the finish line. With labor/delivery, there's no point where you can say, "Ok. I'm done." ;)
