I don't have IBS but I have crohn's disease, which has similar symptoms of running to the can and such If I have a flare up it's really hard for me to not want to get on the bike anyway. I try to avoid the trigger foods if I know I'm going to go on an organized ride. Thankfully stuff like carbs doesn't set me off Otherwise, if I get hit with pain on a ride I slow down and take deep breaths til it passes. If I find I need to "go" I have no qualms of using a corn field or stopping at someone's house. I have this card from the Crohn's & Colitis Foundation of America that says I really really really really need to use the bathroom, in so many words.

GI issues are fun aren't they?

I have found I feel better if I exercise though, so it's more a matter of figuring out what I can do and when I should take it easy. But never *too* easy.
