Wow--this is a long thread to read. Thank you so much to the regular posters here for sharing your experiences. I am a new runner and have learned so much by reading your trial and error posts.
I am training for a 25K race next weekend (May 13) and have been looking for something to prevent the post-long run cramping and diarrhea issues I have recently aquired. I thankfully don't have a problem during my runs and never a problem with mileage under say 6 or 7. I say recently aquired because I have only been running since January and my >7 mile runs only started about 6 weeks ago. (I'm
almost 33, female and have 5 kids--no real "traumas" during birth and no poop issues other than after a long run)
From the info I read here, I tried taking one Immodium yesterday before my 10miler and made more of an effort to hydrate during the run (water only). It helped, but I still had some cramping for a couple hours afterwords (I took another Immodium with lots of water after the first "episode" post-run). I think I might try 2 before the race on Saturday and will eat an early dinner Friday, maybe a banana and gatorade early on race morning. I also wear a camelbak during my long runs and won't need it for the race--I have read elsewhere that wearing something tight around the gut may be a factor too??
Anyway, if you more experienced runners have any specific advice for pre-race diet to avoid gas, cramps and diarrhea, please let me know! I am not intending to "race" this race. I entered it with a friend with the goal of just wanting to run that far once in my life (she's actually already dropped out due to 2 stress fx). That said, I know the "nothing new on race day" is a common reply here, but I am looking at this as just another long run with about 2000 of my newest friends.

I'd really like to be able to celebrate this accomplishment with my kids, DH and extended family members rather than spend most of the afternoon on the pot!
sorry so long--thanks for reading
