Runners Belly
#1

Sometimes I find that once I have been running for about 40 min or so I get runners belly. Sometimes I am able to hold it in, sometimes I have to stop the run and find a toilet (or bushes...). I have a theory it may be lactose related, for my mum is lactose intolerant, and I may have gotten it from her, and the only time it has been 100% absent is where I have been on a vegan diet (that included no dairy). Other theories also include - chewing too much gum, eating fatty foods the night before etc.
Have other cool runners had runners belly and overcame it? What did you do?

I find that if I run first thing in the morning and I've been able to have a good toilet movement before I head out I experience no problems.
However, if I run in the afternoon and I have a whole days worth of food in there and I almost always have problems.
Timing is everything.

If you search on CR you'll find that runs on the run is not an uncommon complaint and that there are various suggestions as to causes. I've wondered if there can be a psychological component to it sometimes, ie. a self-fulfilling anxiety.
Not sure whether it would have anything to do with lactose intolerance. I became lactose intolerant a few years ago following a bout of giardia or similar. This was a year or two before I took up running. Perhaps it makes you more susceptible, but if so it was a temporary effect in my case.
Kato speaks wise words.

Most humans have slow digestion production line. From the time of food delivery to the body, to the time of delivering the final product out of the body,
the time delay is 48H average, but ideally should be less than 24H.
so for the average 48H production line, what is the situation : with 3 big meals a day and another 3 snacks per day, within 48H the production line holds about 6 big and 6 small unfinished products.
as the production line gets the strong long lasting vibration (running), the unfinished products get moving bit faster and at least of gets out soon.
Instead of complaining, you should be celebrating, that at least 1 load is not rotting inside you as long as usual.

Everyone passes at somestage. I note before races many people (from what I have heard from friends) have 'the runs' so I was putting it down to nerves. As for training, not sure. I can relate though especially after I got Giadia over christmas.

I also found that by changing the food I had prior to strenous workouts that Ive practically eliminated the need to rush for the loo at the end of a run..

Did read in Runners World sometime ago that coffee tends to push "things through" abit quicker hence can cause this. So have stopped drinking it before a run and has helped. I do try to have a hot cup of tea maybe an hour before a run so does the same thing and you are therefore able to go to the toilet before the run.

It doesn't always happen, but when it does it's very resassuring to know where the available facilities are.
Happy running

Ah, the old, "running in a glycogen depleted state or running in a fasted state," question.

I find that the need to "go" during a run is cyclical. I will have a week or so where it strikes during every run, and then several months where there is no issue whatsoever. I can't see a pattern to how this cycle plays out.

In the past two weeks I have dropped my sugar intake (mostly fructose) by half and I'm finding that the need to go during the morning run has also decreased. I'm also finding that I can get through my morning run without a snack first (it was previously corn thins and a little banana).
My last long run was still a bit tricky but I had eaten a fairly large meal the night before. During the run, I refueled with low fructose muesli bar without any hassles. Gels are the devil for my system!
Maybe see if there is a pattern to your stops, especially around distance and any food or drinks taken on board...
Also, study the Mara map so you know where the toilets are located! Will make it a lot easier to plan a stop if you need.... And pack some easy to access toilet paper.. Less time wasted the better!

I have seen the evidence that what I have eaten at 6pm is gone by 6am the next morning, so less than 12H for me.
So unless I've had a midnight snack or breakfast there is NOTHING in mine ...
If I run in the afternoon I normally have to go again after warmup.

I also run in the tri shorts always and if needing a number one, just chuck some water on and go. Takes some practice to go on the run, but this works for me the best.

I need to have done #2's before I head out first thing in the morning (brekkie or no brekkie) or I am guaranteed to need to find a porcelain friend from about 40mins onwards. It often takes me a good 30 mins after getting up before I have movement down there, so on my Saturday long run where I set off at 5am, I cannot go beforehand (because I can't be bothered getting up much earlier) so I know every toilet location on my long run course. It's pretty inconvenient actually as it's always hard to guess how much impact the ~5minute rest has had on my run and in particular my last 10K pace.

Quarter Pounder? Yep!

Race Eve - Protein & Complex Carbs only. Early dinner, about 3pm. No Sugar basically.
Vegemite on Toast & Coffee about 4 hrs prior to take off. I have tried the glass of warm water with no success. Coffee seems to do the trick for me.
Gels, gatorade, fruit, lollies etc on the run. No negative effect. About 15 hrs of only simple, low GI foods works for me. Avoid Garbo Loading.
Good Luck

I ate dinner early last night - around 5pm, had toast and honey (no butter) about 1h30 before starting run this morning. I ran the whole 20K feeling great, no tummy rumbles at all. However, the second I reached home I literally dove onto our ceramic throne and whooooa, it was not normal, put it that way! I felt totally normal afterwards.

I have been having trouble on my last 2 longer runs ... which were both around 1.5 hours. I normally have a very high fibre diet so I think this may be part of the trouble ...so have decided to do a short run today as a lead up to GTR2012 on Sunday and hopefully tummy will behave itself .. I'll try your suggestios for Race Eve etc and hopefully that will help.. ...
Going out shortly .. before the day gets away from me...hope tummy behaves..

may I ask what you changed the food to Flash 187? As it would be great to run on Sunday in the GTR 2012 without having No. 2 issues...

But today, there was a new version: set out for 20km of hill and trail; got to 13km, needed a toilet break. Had a few mouthfuls of water before setting off again... and within 2km felt like vomiting. This has never happened before. Very weird. Did not actually vomit, and the feeling passed, but I quit at 18km, a little shy of target.

I've tried changing my diet (which is generally very high in fibre), eating different food before the race, not eating before the race, eating earlier before the race, coffee to get things 'started', hot water - nothing has worked. I can go to the toilet four times before racing and still have to pull over during the race. It's happened in my last three marathons (in one causing me to lose the 2:50 pace group, grrr) and it's not fun!
I think (in my case) nerves has a lot to do with it (I get REALLY nervous before any sort of race, even the little ones), combined with the fact that it now constantly plays on my mind which may make it a self-fulfilling prophecy.
People have suggested trying Imodium but I'm not sure how that stuff works and I don't like taking stuff without knowing what it's doing to my body.

There are a number of toilet paper / soft wipe products that pack really small (about ten to a pack) that are perfect for carrying whilst running.
