This isn't a pretty subject, but it is every runner's nightmare. And it happens to a lot of us during marathons, half-marathons, or during training for long runs. Runner's diarrhea, or having to go during a long run can ruin everything for us.
I have been fortunate that this is a very rare occurrence for me(I've had stomach problems and near diarrhea, but didn't go during the run, just cut it short), but this is due to almost always being able to empty myself before long runs and running later in the day.
Unfortunately, I have some group runs scheduled for early in the morning, even earlier than when I usually have a bowel movement. This can be problematic for me. Although I keep going to bed earlier and earlier, and getting up earlier too, I still have my movement after the time the next race is scheduled for. My digestive system seems to take an hour or two to wake up after I wake up. I can wake up at 5 AM alright, but 4 AM is pushing it(no pun intended).
So what can I do to stimulate a bowel movement before a run? And what can I do to slow my digestion afterwards to prevent a bowel movement during the run? I know I can use laxatives like magnesium sulfate or citrate, or prunes or prune juice, but it usually takes a while for these things to work. And calcium does the opposite of what magnesium does. Are there any types of exercises I can do to help stimulate a movement? I know ab exercises may help and so can exercise in general, but anything else? I also drink plenty of cold water as soon as I wake up. Would hot water be better? What can I do the night before? I'd say my bowel movement frequency is about 18 to 24 hours. I already know not to eat high fiber foods before long runs, though I normally eat a high fiber diet on days I am not running.
I would preferably like to have a movement within 30 minutes of waking up, or even upon waking up, if possible. How do the runners here deal with this?
