RUNNING COMFORT
How can I stop getting a side stitch when running?
Ease off for a side stitch, then check pacing and meal timing
For a familiar side stitch that appears during running, slow down or walk and let it settle. A gentler start and changes to food or drink timing may help, but no single breathing trick reliably prevents every stitch.
A stitch is a description, not a complete diagnosis
Exercise-related transient abdominal pain is the research term commonly associated with a side stitch. Morton and Callister’s review describes several proposed explanations and notes that the cause remains uncertain. It is too simplistic to state that every stitch is definitely a diaphragm cramp or evidence of poor fitness.
The word transient matters. A familiar ache that occurs with running and settles when you ease off is a different situation from severe, persistent or unexplained abdominal pain. Do not force every symptom into the stitch category because it happened during exercise.
What to do during the run
Reduce the effort or walk. Let your breathing become comfortable rather than trying to hold a target pace. Some runners find relaxed breathing or gentle pressure over a familiar stitch helpful, but these are not guaranteed fixes.
If the pain does not settle, stop the session. Continuing to test an increasingly painful symptom gives you little useful training information. Severe or persistent pain, fainting, chest pain, fever or repeated vomiting needs medical assessment; urgent symptoms need urgent care.
Review the context
| Question | Example note |
|---|---|
| When did it begin? | After the fast opening minutes |
| What had you eaten or drunk? | A larger-than-usual meal close to the start |
| What changed on the route? | A downhill section followed by a climb |
| What helped? | Walking until the discomfort settled |
These notes can identify patterns without claiming causation. If the same problem repeatedly appears in a similar situation, you have a more useful starting point for adjusting the routine or discussing it with a clinician.
Change one thing next time
Try an easier start, or move a familiar meal farther from the session. Keep the other conditions reasonably similar if possible. Avoid taking an oversized drink immediately before setting off simply because you are worried about hydration.
Do not respond by avoiding food and fluids indiscriminately. That can create a different problem, especially on a long or hot outing. The aim is a comfortable, adequately fueled routine, not proving that you can run with as little intake as possible.
Use the recording to locate the episode
In Runome, inspect where your pace changed and compare the surrounding effort data if it is available. Your notes explain why you slowed; the chart alone cannot distinguish a stitch from a traffic crossing or a deliberate recovery break.
Read meal timing before running and breathing and effort for related practical decisions. Recurrent pain warrants advice even if you have found a way to run through it. A data trend is not a diagnosis and cannot rule out another cause.
