Ok, surely I am not the only one who wonders about whether she will need a wee during my first marathon? i have a target time of under 4 hours and dont want to have to stop and queue for the loo half way around. What is normal. if I get nutrition/hydration correct might I get away with not going or is it inevitable and therefore I should factor this in! I know Paula Radcliff just stopped and went do many people do this? Hey if it's good enough for Paula..... Thoughts very much appreciated!
