The Common Running Injuries and How To Avoid

Running is a great way to stay fit, but it does carry some risk of injury. Knowing about common running injuries, what causes them, and how to prevent them can help you stay healthy and keep running.

Common areas where runners often get injured

1. Foot or heel: plantar fasciitis
2. Achilles tendon: Achilles tendinitis
3. Shin: shin splints (medial tibial stress syndrome)
4. Knee: runner’s knee or IT band syndrome
5. Hamstring: muscle strain
6. Hip flexor or hip: overuse strain
7. Lower back: issues from poor posture or weak core muscles

Descriptions of common running injuries

• Runner’s Knee (Patellofemoral Pain Syndrome): This injury causes pain around or under your kneecap, especially when running, squatting, or going up and down stairs. The discomfort often gets worse with prolonged sitting or after intense activity. Common causes include weak hip or thigh muscles, poor running mechanics, overuse, or improper footwear. Prevention strategies include strengthening your quadriceps and hip muscles, maintaining good running form, and ensuring your shoes provide adequate support.
• Shin Splints (Medial Tibial Stress Syndrome): Shin splints present as pain or tenderness along the inner edge of your shin bone. The pain usually starts at the beginning of a run and may ease as you warm up, but it can worsen with continued activity. This injury is especially common among new runners or among those who quickly increase their mileage or intensity. Other contributing factors include running on hard or uneven surfaces, wearing unsupportive shoes, or having flat feet. To prevent shin splints, gradually increase your running volume, wear appropriate footwear, and incorporate lower leg strengthening and stretching exercises. If pain persists, taking a break and using ice can help with recovery.
• Achilles Tendinitis/Tendinopathy: This injury causes inflammation, stiffness, or pain at the back of your heel and lower calf, often making it difficult to push off with your foot. The discomfort usually feels worse in the morning or after periods of inactivity, sometimes easing as you warm up but returning with continued activity. Common causes include repetitive stress from running, sudden increases in training intensity, tight or weak calf muscles, and improper footwear. Runners may notice swelling, tenderness, or a thickening of the tendon above the heel. Ignoring these symptoms and running through the pain can worsen the injury and lead to partial tears. To help prevent Achilles tendinitis, gradually increase your running intensity, stretch and strengthen your calves, and use supportive shoes. Early intervention—such as rest, ice, and gentle stretching—can prevent chronic issues.
• Plantar Fasciitis: This injury causes sharp, stabbing pain in your heel or along the arch of your foot, especially with your first steps in the morning or after periods of rest. The pain often lessens as you move around, but can return after prolonged standing or intense activity. Plantar fasciitis is usually caused by excessive running, inadequate foot support, tight calf muscles, or sudden increases in training volume. Risk factors include having high arches, flat feet, or being overweight. To prevent plantar fasciitis, wear shoes with good arch support, stretch your calves and feet regularly, and vary your running surfaces when possible. If pain develops, early treatment with rest, ice, and gentle stretching can help prevent chronic discomfort and allow a quicker return to running.
• IT Band Syndrome: Iliotibial (IT) Band Syndrome produces aching, burning, or sharp pain on the outside of your knee, which can sometimes radiate up the side of your thigh toward your hip. The pain typically starts after a certain distance into a run, intensifies with continued activity, and is often worse when running downhill or after long runs. Causes include overuse, weak hip and gluteal muscles, poor running mechanics, and excessive running on sloped surfaces. Runners may also notice a snapping or popping sensation on the outside of the knee. Prevention involves strengthening the hips and glutes, maintaining proper running form, and avoiding sudden increases in mileage or intensity. Foam rolling and stretching the IT band and surrounding muscles can also help.
• Stress Fractures: Stress fractures are tiny cracks in a bone caused by repetitive force and insufficient recovery. They most commonly affect the foot (metatarsals) or shin (tibia) in runners. Symptoms include localised pain that worsens with activity and improves with rest, swelling, and sometimes bruising or tenderness to touch. Unlike muscle soreness, stress fracture pain is persistent and can become severe if ignored. Risk factors include increasing mileage too quickly, running on hard surfaces, poor nutrition, and having a history of bone stress injuries. Prevention strategies include gradually increasing training volume, eating a calcium- and vitamin D-rich diet, and incorporating rest days. If you suspect a stress fracture, stop running immediately and see a healthcare provider for diagnosis and management, as running through this injury may lead to a complete fracture.
• Muscle Strains: Muscle strains are common running injuries, especially in the calf or hamstring. These occur when a muscle is stretched beyond its capacity or suddenly contracts, leading to microtears in the muscle fibres. Typical symptoms include sudden sharp pain, tightness, swelling, weakness, or bruising. Strains often result from overexertion, inadequate warm-ups, fatigue, or rapid changes in speed or direction. Risk increases for those who skip stretching or have underlying muscle imbalances. To prevent muscle strains, perform dynamic warm-ups before running, maintain a regular stretching routine, and gradually build strength. If a strain occurs, use the RICE method (rest, ice, compression, elevation) and avoid returning to activity until fully healed to prevent re-injury.

What causes running injuries?

• Overuse: Increasing your mileage or speed too quickly (doing too much, too soon).
• Weakness: Not having enough strength in your core, glutes, or hips, which can lead to poor running form.
• Footwear: Wearing shoes that are worn out or not right for your foot type.
• Surface: Running often on slanted or uneven ground can increase your risk of injury.

How to help prevent running injuries

• Increase your training gradually and avoid making big jumps in your mileage.
• Add strength training to your routine, focusing on your hips, glutes, and calves.
• Replace your running shoes every 300 to 500 miles.
• Make sure to rest and recover enough between your runs.

Additional tips:

• Listen to your body and take care of pain early to avoid more serious injuries.
• Try cross-training by adding low-impact activities like cycling or swimming to reduce repetitive strain.
• Warm up and cool down by doing dynamic stretches before and after your runs.
• If pain does not go away or gets worse, talk to a medical or running specialist for advice.

In summary, understanding the most common running injuries, their symptoms, and prevention strategies is essential for staying healthy and enjoying your runs. By listening to your body, following gradual training progressions, wearing the right footwear, and incorporating strength and flexibility work into your routine, you can minimise your risk of injury. Remember, early intervention is crucial—addressing pain promptly helps ensure a faster recovery and allows you to get back to running safely.
