I have just read with interest the advice on immodium and being caught short, during a race and on training runs. My problem is more to do with the waterworks! I, of course hydrate before a race with drinking water. Both about 2 hours before and directly before a race. The excitement of the race makes me want to 'go' quite soon into the commencement of the race, most uncomfortable. Is it accepted practice or not to find a spot on the verge side of a race, or not. Oh I forgot to mention I am female. Men can stop very easily. I have never a female stop, but maybe I have never noticed. I would welcome andy advice and experience on this matter, as to how much water to drink before and how long before a race/training, and if anybody has stopped to carry out the necessary.
