Nearly every runner has experienced it, and if you’re reading this, you’ve probably been stopped in your tracks by one of these pesky side stitches. The good news is that side stitches are completely preventable and treatable once you understand what causes them and apply the right techniques.
I’ve been running for years, and while side stitches affect up to 70% of runners, they don’t have to derail your training. These temporary pains—officially called exercise-related transient abdominal pain—are your body’s way of saying something needs tweaking. Maybe it’s your breathing, your pre-run routine, or how fast you’re pushing yourself.
In this guide, I’ll share what I’ve picked up about why side stitches happen and the practical steps you can take to keep them at bay. Plus, I’ll give you real-life fixes for dealing with them quickly if one does sneak up mid-run. No need to let a stitch ruin your miles.
Understanding and Preventing Side Stitches
Side stitches usually pop up for a reason, and you can often avoid them by paying attention to a few key triggers. Knowing what causes that sharp pain and prepping your body beforehand will make your runs a lot more comfortable.
Key Causes of Side Stitch Pain
Lots of things can set off a side stitch while running. Figuring out your own triggers is half the battle.
Diaphragm fatigue is the main suspect. Push yourself harder than usual and your breathing muscle can just cramp up.
Weak core muscles don’t help either. Your abs stabilise your torso, and if they’re not pulling their weight, your diaphragm has to work extra hard.
Improper breathing—especially shallow, chesty breaths—can bring on a stitch too. Your muscles need more oxygen when you’re running, and if they’re not getting it, things get cranky fast.
Other usual suspects:
- Running too fast for your current fitness
- Poor posture (think hunching forward)
- Eating right before your run
- Dehydration or not enough electrolytes
- Sudden jumps in pace or distance
Some research even suggests the up-and-down motion of running can irritate the ligaments holding your organs in place. Who knew?
How to Prevent Side Stitches Before Your Run
Stopping side stitches starts before you even head out the door. A little planning goes a long way.
Strengthen your core with regular exercises. Planks, dead bugs, bird dogs—these are your friends. Try to fit in 10-15 minutes, three times a week. It really does make a difference.
Warm up properly. A couple of minutes of brisk walking, then ease into a slow jog. No need to launch straight into a sprint.
Dynamic stretches are helpful too. Things like leg swings, high knees, and gentle torso twists get your body ready to move.
Practice deep belly breathing before you start. Take a few slow, deep breaths and focus on filling your lungs. It sounds basic, but it helps.
Watch your timing with food. Big meals right before a run are asking for trouble. Give yourself 2-3 hours if you’ve eaten something heavy, especially fatty or high-fiber foods.
Hydration basics:
- Drink water throughout the day, not just before your run
- Keep your electrolytes balanced
- Skip sugary drinks right before exercise
- Stop drinking about 15-20 minutes before you start
And don’t forget posture. Keep your shoulders relaxed. Hunching forward just makes things harder for your diaphragm.
Techniques to Stop a Side Stitch Mid-Run
If a side stitch sneaks up on you during a run, don’t panic. You can usually get past it without calling it quits. A few tweaks to your breathing, pace, and posture will help your diaphragm chill out.
Adjusting Your Breathing Technique
Honestly, changing up your breathing is usually the fastest fix. Move from shallow chest breathing to deeper belly breaths. Sounds simple, but it works.
Try the uneven breathing method: If you’re used to inhaling for two steps and exhaling for two, try inhaling for two and exhaling for three. This shifts which foot you land on as you breathe and helps balance out the strain on your diaphragm.
Focus on exhaling fully: Take a big breath in, then push all the air out through pursed lips. Sometimes just getting rid of that stale air helps your diaphragm relax.
Slowing Down and Active Recovery
Sometimes, you just need to back off the pace. Drop to a gentle jog or a brisk walk instead of stopping completely.
Walking recovery: Slow to a walk, take deep, controlled breaths, and try raising your arms overhead to open up your chest. It feels a little silly, but it works.
This keeps your blood moving and gives your diaphragm a breather. Once the pain fades, ease back up to your usual speed.
Pressure and breathe method: Press your hand over the painful spot, take a deep breath in, press down a bit, and forcefully exhale. Do this three to five times. It’s surprisingly effective.
Stretching and Pressure Relief
Some light stretching on the go can loosen things up. These moves go right after the cramped muscles.
Side bend stretch: While walking or jogging slowly, lift your arm (on the side with the stitch) overhead. Lean away from the pain to stretch your torso.
Torso rotation: Keep your hips facing forward and gently twist your upper body from side to side. This can help loosen up the area around your ribs.
Stop and stretch: If it’s really bad, stop, reach both arms overhead, and lean away from the stitch. Hold for 15-20 seconds. Sometimes that’s all it takes.
Improving Core Strength and Posture
Poor posture while running can make side stitches worse by putting extra pressure on your diaphragm. Standing tall and keeping your form in check goes a long way toward avoiding those annoying cramps.
Posture check mid-run: Try pulling your shoulders back and lifting your chest just a bit. If you start to hunch, your diaphragm gets squished and breathing gets tougher—nobody wants that.
Engage your core: Lightly brace your abs to help support your spine. No need to suck in or clench—just enough to give your breathing muscles some backup.
Quick core activation: Gently draw your belly button toward your spine, but keep your breathing steady. This wakes up your deeper core muscles and lets your diaphragm move more freely.
