After signing up to do the Moonwalk with a group of girls in the village, I received a pack which went into a huge amount of detail on how to keep yourself safe from the rest of the human race (which was slightly alarming, I was hoping for something a little more "yay! go you!" than "avoid quiet pathways...lined with bushes where someone could be hiding") provided lots of encouragement to spend money on branded kit, and contained a plan on how to get yourself to the required level of fitness to walk a marathon in the middle of London, in the middle of the night.
What it didn't cover was something so crucially important that it was the first question that was raised when we got together to discuss the training - where are you supposed to wee? You may laugh, mock even, but when you're being encouraged to be out walking for four hours at a time, whilst drinking enough water to remain 'well hydrated', it's likely nature will come calling.
Thing is, the rules for weeing as a girl or woman changes as you age, so which one was going to be right?
