Congrats on finishing the R&R half.
Your stomach issues could be caused by myriad things. You didn't mention cramping so I'll assume that isn't the cause of pain. It could be as simple as a gel you consumed during the race, or sports drink. I guess a good question for me to ask is: "Does the pain come only after eating, or does it occur when you don't eat anything after a long run as well?"

I get really naseaus if I don't drink Gatorade after a long run - for me, it's because I'm dehydrated and water doesn't seem to work as well.

I've been getting abdominal pain after running for years. I find it occurs regardless of whether I eat or drink (although initially I may have thought it was sparked by drinking water). When I first experienced symptoms, it only occured once a month or so after a fast run over 4 or 5 miles. The frequency and intensity increased over the course of a year until eventually it occured after every run.

I've been to several doctors to explore possible causes ranging from hernia to spinal injury. I have never found the cause, nor have I been able to elimate the pain, which can last anywhere from 2 hours on a good day to 6 hours on a bad day. Unfortunately, I finally had to stop running.

Every now and then though, just to stretch my legs, I'll knock out a 3 mile jog. I find I'm ok, until I run more than 3 or 4 times in a week. Then the pain returns.

I realize this information probably isn't helpful to you at all, but you're the first person I've heard of that experiences something similar to what I've been dealing with. All of my doctors and friends have said I seem to be an anomoly.

Maybe there are others who have the same issues -- I don't know. Just thought I'd share.

Good luck

The last half marathon I ran I experienced no stomach pain at all. I drank a liter of water for 7 days befoer the race and did a carb load 2 days before. The morning of the race I ate a normal breakfast 3 hours before. During the race I dranks small cup of water every 2 miles and chewed gum to keep my mouth from drying out...When I finished I felt fine..no stomach distress whatsoever! I had a half of a bagel and some peanutbutter 45min. after the race...no problem!

I think you really have to experiment on yourself to see what might be causing the stomach pain and what might alleviate it. For me, it depended more on what I ate the night or morning before a long run than what I ate during it... complex carbs, or just too much food, seemed to be particular culprits. I had to carbo-load, just not too enthusiastically! But others have contributed that what they ate during, or even after, the run, contributed to stomach pain more than what they ate prior.

I'd try to analyze the whole course of my nutrition, before, during and after the run, and try to vary one factor at a time. I do think that stomach pain after a long run is fairly common, although generally speaking with careful attention and experimentation, you can figure out a way around it.

Runners tend to have more stomach problems anyways. Probably due to swallowing air while running and if the problem seems to be worse after long runs-it's most likely due to dehydration (so drink plenty of fluids). Also running will suppress your appetite for about 1hr or more afterwards, so you won't feel like eating.

stomach pains can mean many things, but for you it is an obvious case of hydration problems. quit the gatorade. the water taken with gm of sea salt,or more, if using on food like you should be doing anyway. ounce of water for every pound when doing long endurance runs or activity.

balance of nutrition means proper amino acids and absorbable vitamins, such as vit.C (A & E) along with potassium, calcium (this is the hydroenergy pump for cells, along with sodium) so, don't let your doctor tell you to cut the salt, as long as its sea salt, you are probably fine.

why quit gator? the stuff is loaded with sodium, the sodium chloride is infinitely inferior to sea salt (82 vitamins and minerals) and contains corn syrup, which is the one of many reasons for ill health and obesity in this country USA.
