I was wondering if anybody could recommend anything to help prevent an upset stomach when running? I suffer badly from stomach cramps and regularly have to stop to go to the loo when I'm out. I am running the Frankfurt Marathon in October and would really like to get the problem under control as it will obviously damage my time if I have to stop during the race. I'm not too sure whether this can be controlled through diet or taking something before I run. Any advice would be greatly appreciated! Many thanks.
