Strong urge to use the bathroom during a run:

That's actually really typical. I will let someone who is capable of running for more than five minutes advise you on what to do about it, though.

Does anyone else experience this?

Yes.

Do you have advice on how I may prevent this or what may be causing this?

Getting up and stirring around for a bit until my bowels "wake up". Pooping with all of my might before the run.

Other poop related comments you'd like to contribute?

Finally had a solid bowel movement today. It wasn't S-shaped, but it was solid. Please feel free to learn more about my Watery-To-Chunky-To-Semi-Solid-To-Beefy-Solid-Stool journey here: http://www.myfitnesspal.com/topics/show/874580-finally-i-did-it I promise that I'm not selling anything!

i always get up about 30-40 minutes before, have coffee, the warm liquid helps. move around and wake up your sytem. It has worked for me for years.

Very common problem among runners. Just go before you go. "PRP" = pre-run poop.

Common.

Running is a natural laxative.

*Walks in, sees "beefy" next to the word "stool" and leaves.*

Don't eat beforehand, or wait an hour or so for things to start digesting.

I get that feeling but then I slow down to a fast walk and the urge goes away, so I dont know, I try to ignore it

Two words: Compression shorts

If a seam busts, you're gonna have this happen:



Best to vacate before running than try to block the exit.

does it come with the kid laughing too???

I found this on this site: http://www.shutupandrun.net/2012/05/how-to-not-crap-yourself-on-run.html

Following are a few sure-fire ways to minimize the risk of crapping one’s pants while running and racing:

The single most helpful thing for me has been to eliminate or drastically reduce fiber, dairy and fatty foods up to 36 hours before a long run or race. Typically, my diet is pretty rich in roughage, whole grains, beans, etc. But, I really do change things up the days before a race. I take in lots of water and reduce my intake of fruits, vegetables, yogurt, cheese and any higher fat foods. I’ve had great success with this plan.
Overly exerting myself makes things worse. On long runs, I stick to long-run pace (60 to 90 seconds slower than my ideal marathon pace), and this helps significantly. In races I am usually exerting a great deal, so this plan doesn’t work well under those circumstances.
Don’t laugh, but I try to get on a strict poop schedule. I train my body by eating and sleeping with a routine in mind (as much as possible). A cup of coffee in the morning usually gets stuff going. Nine times out of ten if I can get something out before a long run or race I’m good to go. Occasionally there will be a lingering nugget in there that causes problems, but not usually.
It helps to not eat the two hours before a long run or race. Give your body time to digest your pancakes. Once, in all of my naiveté, I ate a huge bowl of beef stroganoff right before a run. This was a like a huge practical joke I played on myself.
Pre-race nerves are definitely an issue and can get stuff moving when you wish it would stay put. That’s why I’ve been known to take multiple dumps on an airplane. I hate to fly and I’m nervous. Do everything in your power to minimize any extra anxiety on race day. Give yourself enough time, breathe deeply, think about the nap you will take later. Distraction is a great tool because the mind can only think about one thing at a time. Don’t let it take you hostage.
I never mix gels/chews with sport’s drink. I choose one or the other. I find that mixing various sugar types and chemicals doesn’t bode well for me and my colon. Ever hear the saying, “Sport’s drinks and gel, your stomach will give you hell?”
I hate to stop and do business during a race. But, it does help to have a back up plan in your mind. Know your potty options. Plan long runs around your favorite bushes or gas station bathrooms. Study your race map or drive the course so you know your potty-ops. Taking charge and knowing what to expect may reduce some poop anxiety.
I know some people take Imodium to calm things down. I have not tried this mostly because that stuff constipates me. Yes, that is the point, but I find it rally messes with my system and I have a hard time getting back to normal even days later.

Here’s to crap-less runs!

just harvest that s**t and you'll never pay full price at the butcher's counter again!

This is probably my favorite line of this.

Ikeda's team then combined them with a reaction enhancer and put them in an exploder. What eventually came out was no filet mignon

Hate Runner's Trots... Caused by certain muscles starting to relax due to blood flow to your legs. I've battled with this from time to time. I'm not sure what time you run, but this is an issue for me in the Summer time because I like run early before the heat. I make sure I watch the time and what I eat the night before. Lay off late night heavy meals if you can.

If I know I'll have an issue, I run trails with lots of bushes and carry TP in my shorts pocket.

I don't have this issue so much in the evening. Good Luck

Wow, I have to admit this post is a hoot...but I know it's a serious topic so let me get on with it.

I usually drink coffee in the am. and run either at noon or in the afternoon after work. By this time I'm cleaned out. I agree with some of the posts here that running is a laxative. That is a good thing. You have to train your body somehow to not have the desire to go while you are running. Maybe try an alternative schedule and run in the evening?

Good luck!

By the way, if anyone comes in here and suggests you start taking immodium before running because going to the bathroom is inconvenient, I'mma gonna rage. One of these threads came up about a month ago, lots of people gave good suggestions, one idiot suggested immodium, and the OP's takeaway was that purposely constipating yourself (she didn't have diarrhea, just stopping the treadmill was inconvenient with her schedule and she didn't like sweating on the toilet) seemed like the best solution. Intentional constipation on a regular basis. Seems legit.
