There are definitely ways to prevent a run-induced stomachache, but if it's too late and you're past the point of no return, then listen up: we continued our talk with DIAKADI running and training coaches Elijah Markstrom and Angela Tieri to get the skinny on treating an upset tummy after a hard run.
If you got to this page because you currently have a stomachache, the first note that Elijah made was to consider what you ate, and when. "When and what did I eat prior to the run, what did I consume during the run, and when and what will I consume after the run?" Elijah said that some stomach issues are the result of chronic issues, while others are more acute and circumstantial.
"When performing high-intensity exercise, blood is shunted from digestion to the periphery, in order to accommodate the oxygen demand to the working muscles," said Elijah. In other words, your stomach is freaking out because it can't digest properly when you're running — meaning much of these stomach issues come from food and digestion.
Another factor to consider: are you on your period? Angela told us that women who run during their cycle are subject to extra stomach distress and sensitivity, and suggests you "run a route with public restrooms," if that's the case for you. Don't say we didn't warn ya.
In summary, you're feeling crappy for one of these reasons:
Now let's get into how we prevent and treat these issues.
While these tips are remedial on a case by case basis, if your issues are chronic and seem to be coming up each time you run, then it's time to consult your doctor.
