Running then RUNNING?

What you describe isn't unusual or abnormal, but just kind of inconvenient. Everyone has their own GI patterns-- I usually run in the morning, about an hour after waking up. I have a light breakfast and tea which gives my body a chance to "clear out" before I run. If I run later in the day or if for some reason I run really early before nature calls, I will have to stop during the run-- I just know this.

So get to know your body's patterns, and be prepared. You may try to experiment with running at different times of the day to make things more conveniently timed. Or you may find it easier to stop earlier in the run for a break so that you won't have the sudden emergency urge when you finish.

always have a backup I know my body's routine, and it only seems to be after the 10+ mile runs, I knew some of the shameless BT folks would come through.

I am trying to figure out why you think this is a problem? Its the best "problem" you could have that's related to this particular subject. Could be much worse - many runners have issues DURING a run when you are as far away from a bathroom as possible and things need to exit RIGHT NOW.

Why would you want to stop this?

It gives some tips about lower fiber, etc
I know a few people that have this issue. Most carry TP with them while running in case of an unexpected pit stop.

You might want to look at what you eat before running to see if there's a common pattern. I know I can't have wheat or milk products within several hours of running if I expect to get through it without a pit stop. Similar problems with dairy without running, but I've never had a problem with wheat, except before running. Apparently I just don't digest it as well as rice or oats. If you are eating low-carb/paleo, wheat may not be an issue but could be a low-level intolerance to something else in your diet, either the morning of or night before. Also, in my experience heat and intensity can definitely speed up GI issues. I need to be a bit more careful about what I eat before/during running if it's very hot and humid, and/or it's speedwork or a race.

In any case, for morning runs, getting up a bit earlier, having a little hot coffee or tea, and being active around the house or yard may be helpful to get things "moving" before your run, rather than during. I try to spend 20-30 minutes after getting up making beds, feeding pets, taking out garbage, setting out things for work, etc. before hitting the road. That also allows me to get my muscles warmed up a bit, run when it's lighter out for most of the year (it varies less for me than most, living in the tropics) and have a quicker transition to commute after my run.

I'm glad you posted this lol I've been experiencing the same thing bud! I've become accustom to it and am fortunate for it to hold off until post run (no matter the mileage; it could be a 3 or 10 miler and the "urge" is just the same). My body has adjusted to the point where I can run but as soon as I get back to the house no one better be in my way of that bathroom! I generally do my runs in the evening after work and it's 50:50 whether before or after dinner. However, I've been trying like the dickens to get up before work to do my runs but until I do that a little more consistently, I won't be able to tell if that fixes the problem.

The funniest sign I remember from my last HM was "run now, poop later"

haha awesome
