🦵 Why You Might Have Knee Pain When Running

Knee pain from running usually results from a combination of poor form, muscle imbalances, overuse, or inappropriate footwear. Here are the most common culprits:

1. Runner’s Knee (Patellofemoral Pain Syndrome)

Characterized by pain around or behind the kneecap, especially when going downhill, squatting, or sitting for long periods.

2. Iliotibial (IT) Band Syndrome

Pain on the outer side of the knee, caused by inflammation of the IT band rubbing against the knee bone.

3. Tendonitis

Inflammation of the tendons around the knee, particularly the patellar tendon. Often caused by repetitive strain or sudden increases in mileage.

4. Meniscus Injury

Pain due to a torn meniscus can be sharp and is often accompanied by swelling or a “clicking” sensation.

✅ How Do I Stop My Knees from Hurting When I Run?

Here’s how to tackle knee pain and keep it from ruining your runs:

🔹 Rest and Ice

If the pain is recent or sharp, take 2–5 days off from running. Apply ice for 15–20 minutes a few times a day to reduce inflammation.

🔹 Check Your Form

Running with poor posture or stride can overload the knees. Keep your knees slightly bent, land softly, and avoid overstriding.

🔹 Strengthen Supporting Muscles

Weak glutes and hips often shift stress to the knees. Incorporate exercises like:

• Glute bridges
• Clamshells
• Step-ups
• Side leg raises

🔹 Stretch Regularly

Tight hamstrings, quads, and calves pull on the knee joint. Stretching after every run can help with flexibility and pain relief.

🏋️‍♂️ How Do I Strengthen My Knees for Running?

Strength training is one of the best ways to prevent knee pain when running. Focus on building stability and strength with these key exercises:

• Wall sits – Strengthens quads and improves knee alignment
• Lunges – Targets quads, glutes, and hamstrings
• Step-ups – Mimics running motion, helps with single-leg strength
• Resistance band walks – Activates hip stabilizers
• Calf raises – Protects the knee from ground impact

Aim for 2–3 strength sessions per week, especially during low-mileage periods.

❓ Why Does My Knee Hurt When I Run but Not Walk?

Running places significantly more force on your joints than walking—up to 3–5 times your body weight. If your form is off or your muscles are weak, this pressure goes straight to your knees, causing pain during high-impact movements like running but not during lower-impact ones like walking.

❓ Is Knee Pain from Running Normal?

Occasional soreness can be normal after a long or intense run. However, persistent or sharp pain is not normal and should be addressed early. If the pain lasts more than a few days, worsens with activity, or causes swelling, consult a physiotherapist or sports medicine specialist.
