Hello runners! How many times have you had to interrupt your run because of a sudden, sharp pain tightening your side? That discomfort — that unexpected stab forcing you to slow down or even stop — is what English speakers call a “stitch,” or side pain, and unfortunately, it affects many of us. It’s not a serious condition, but it can definitely ruin the quality of your training and, at times, your enjoyment.
In the early years of my running journey, I struggled with this more than I’d like to admit. And it’s not something that goes away easily — but with the right strategies, it can be managed and, most importantly, prevented. In this article, I want to share my experience and what I’ve learned to help you say goodbye to this unwanted pain.

The Body and Running: A Delicate Balance
Before diving into causes and solutions, it’s essential to understand what happens inside our body when we run. The lateral abdominal muscles — the musculus obliquus externus abdominis and the musculus obliquus internus abdominis — play a crucial role in trunk movement and core stability. The diaphragm, the main breathing muscle, works in sync with these abdominal muscles. Even internal organs like the stomach and intestines come into play, especially when you eat shortly before running.
While we run, increased breathing and rhythmic movement can disrupt this complex interaction. A high oxygen demand, poor posture, or inadequate nutrition can trigger the painful sensation we feel on the side.
What Triggers the Pain? The Most Common Causes
Side stitches don’t have just one cause; they result from a combination of factors. Digestion is often the main culprit: a heavy meal, especially when consumed shortly before running, can overload the digestive system. Movement interferes with digestion, leading to spasms and inflammation that emerge as sharp pain.
Other common causes include:
- Shallow Breathing: Fast, shallow breathing doesn’t provide enough oxygen to the muscles, leading to carbon dioxide buildup and spasms.
- Weak Core: Poorly trained core muscles fail to stabilize the trunk, increasing susceptibility to spasms.
- Poor Biomechanics: Incorrect posture or compensatory movements can overload lateral trunk muscles.
- Unbalanced Hydration: Drinking too much or too little can negatively affect digestion and muscle function.
Recognizing the Signal: Symptoms and Warning Signs
Side stitches usually appear between 10 and 30 minutes into the run. They are typically described as a sharp, localized pain on the right or left side of the torso that may radiate toward the back. Some runners describe it as a “stab,” a “throbbing pulse,” or a feeling of tight muscle contraction. Sometimes it’s mild and temporary; other times, it’s so intense that you’re forced to stop.
Put Prevention to Work: Preparation and Planning
Prevention is the key to defeating side stitches. Here are some strategies I’ve found particularly effective:
- Smart Nutrition: Avoid heavy or fatty meals 2–3 hours before running. Choose light, easily digestible foods.
- Optimal Hydration: Stay well hydrated, but avoid large amounts of fluids right before or during the run.
- Mindful Breathing: Focus on deep, rhythmic breathing. Try coordinating steps with your breath: inhale for 2–3 steps, exhale for 2–3 more.
- Core Training: Strengthening abdominal and lower back muscles is crucial for stabilizing the trunk and preventing spasms.
- Gradual Progression: Increase distance and intensity progressively to allow your body to adapt.
Handling the Emergency: What to Do When Pain Strikes
If a side stitch hits during a run, don’t panic. Here are immediate strategies that can help:
- Slow Down or Stop: Reducing speed or stopping may ease the strain on your side.
- Side Stretch: Lean your torso toward the opposite side of the pain, extending your arms.
- Compression and Massage: Gently press and pulse on the painful area.
- Deep Breathing: Inhale slowly through the nose and exhale fully through the mouth.
- Hand Placement: Place your hand on the side and gently lift upward.
Invest in the Long Run: Long-Term Strategies
Long-term prevention requires a more complete approach:
- Strength Training: Add core-specific exercises, squats, and lunges to your routine.
- Body Awareness: Pay attention to sensations during your run and learn to recognize early signs of discomfort.
- Training Plan Structure: Alternate short and long distances to boost your body’s tolerance.
- Professional Guidance: If the problem persists, consider consulting a physiotherapist or coach to identify potential biomechanical issues.
Side stitches are a common nuisance, but they don’t have to limit your passion for running. With the right strategies, you can manage and prevent them, enjoying every kilometer to the fullest. Listen to your body, stay consistent with your training, and don’t hesitate to seek help when needed.
Happy running! 🏃♂️✨
