I am a long distance runner -- that is, I run marathons. I also suffer from IBS. My problem is: I often have to make a "run" for the bushes while I'm out on a run. And then it burns like hellfire! The worst is that I sometimes do training runs with other people, and then they have to wait for me to do my business. I have found that if I don't eat for at least twelve hours before a long run, I can usually make it; but then, of course, I run out of steam somewhere around the 15th mile. Any suggestions?

Dear In The Bushes,

Thanks for the question. As I don't personally run anywhere (except to the store for wine), I am going to have to just use some plain old common sense here.

Exercise such as jogging or running can really stir up the bowels. (Someone told me this once.) That's why I don't run. That, plus the fact that I am basically a very lazy person.

Seriously, if I were in your shoes, I would first:

1. Ask my doctor what to do.
2. Follow a VERY low fat, high fiber diet for two days before a run.
3. Perhaps try a gentle enema such as Fleets about two hours prior to the run.
