Running is one of the most effective ways to improve cardiovascular health, burn calories, manage stress, and build endurance. Whether you're training for your first 5K, preparing for a marathon, or simply running to stay in shape, there is one thing that can quickly derail your progress: injury.
The good news? Many common running injuries can be managed with the right approach, and a well-designed strength and conditioning program can help address some of the factors that contribute to them.
With over 27 years of experience in the fitness industry, I've learned that improving performance isn't just about running more miles. It's about preparing your body to handle the demands you place on it. That means improving strength, mobility, stability, movement quality, and recovery.
In this article, I'll break down five of the most common running injuries, what causes them, how to approach treatment, and how the right training program can help you stay consistent.
1. Runner's Knee
What it is: Runner's knee, commonly associated with patellofemoral pain syndrome, causes pain around or behind the kneecap. It may become more noticeable when running downhill, climbing stairs, squatting, or sitting for extended periods.
What causes it?
Runner's knee can develop from several factors, including:
Increasing running distance or intensity too quickly.
Insufficient strength in the quadriceps, hips, or surrounding muscles.
Changes in training surfaces or running routines.
Repeated loading that exceeds your body's ability to recover.
How to treat it:
Temporarily reduce or modify activities that aggravate the pain. Depending on the cause, rehabilitation may include progressive quadriceps and hip strengthening, appropriate mobility exercises, and a gradual return to running. If symptoms persist, consult a qualified healthcare professional for an assessment.
How to help prevent it:
A structured strength program can help improve your ability to tolerate running demands. Exercises such as split squats, step-ups, controlled squats, and hip-strengthening movements may be useful when selected and progressed appropriately.
My approach is to assess how you move, identify areas that may need attention, and build a program that supports your individual goals rather than simply giving you a generic workout.
2. Shin Splints
What they are: Shin splints typically cause pain along the inner edge of the shinbone. They commonly occur in runners who increase mileage, speed, or hill work too quickly, particularly when returning to running after a break.
What causes them?
Common contributing factors include:
Sudden increases in running volume or intensity.
Insufficient recovery between workouts.
Limited tolerance to repetitive impact.
Inadequate preparation for hills or harder running surfaces.
Shin pain can have other causes, including a bone stress injury, so it's important not to assume every case is simply shin splints.
How to treat them:
Reduce or stop running activities that provoke the pain while you determine the cause. Returning to full training before symptoms have settled can make the problem worse. A healthcare professional can help determine whether you need rehabilitation or further evaluation.
If a stress fracture is suspected, stop impact exercise and seek medical assessment.
How to help prevent them:
Build your running volume gradually and incorporate exercises that develop lower-leg strength and control. Depending on your needs, a program may include calf raises, bent-knee calf raises, tibialis strengthening, and single-leg balance exercises.
The objective is to improve your body's capacity to handle repetitive impact, not simply to stretch the painful area and hope it goes away.
3. Achilles Tendinopathy
What it is: Achilles tendinopathy affects the tendon connecting your calf muscles to your heel. Runners may experience stiffness when getting out of bed, tenderness around the tendon, or pain during running, jumping, and pushing off the ground.
What causes it?
The Achilles tendon experiences considerable force during running. Problems can develop when training demands increase faster than the tendon can adapt.
Potential contributors include:
Sudden increases in mileage or speed.
Adding hills or sprint work without adequate preparation.
Insufficient calf strength or loading capacity.
Inadequate recovery between demanding sessions.
How to treat it:
Management typically involves adjusting activities that aggravate symptoms and gradually rebuilding the tendon's capacity through an appropriate strengthening program. The specific exercises and loading strategy depend on the location and severity of symptoms.
Avoid forcing painful stretches or continuing intense running through worsening pain. Sudden severe pain or a popping sensation requires prompt medical evaluation.
How to help prevent it:
Progressive calf strengthening is particularly important for runners. Straight-knee and bent-knee calf raises can help develop the calf musculature when performed at an appropriate level.
I also emphasize gradual progression. Your muscles, tendons, and connective tissues need time to adapt to increases in training intensity.
4. Plantar Fasciitis
What it is: Plantar fasciitis, also called plantar fasciopathy, affects the thick band of connective tissue along the bottom of your foot. One common symptom is heel pain with your first steps in the morning or after sitting for a prolonged period.
What causes it?
The condition can be associated with repetitive loading of the foot, changes in running volume, and reduced tolerance to the demands of training. Footwear and individual foot mechanics may also play a role.
How to treat it:
Treatment may include temporarily modifying running, wearing supportive footwear, and performing appropriate foot and calf strengthening and stretching exercises. Some runners benefit from additional support, such as orthoses, depending on their symptoms and individual needs.
Persistent heel pain should be evaluated to confirm the diagnosis and rule out other conditions.
How to help prevent it:
Your feet are the foundation of every stride, so foot and ankle strength deserve attention in a runner's training program.
Exercises such as controlled calf raises, foot-muscle strengthening, and balance work may be appropriate. Gradually increasing training demands and avoiding sudden spikes in mileage can also help.
A proper assessment can help determine which exercises are most relevant to your needs rather than assuming every runner requires the same corrections.
5. Iliotibial (IT) Band Syndrome
What it is: IT band syndrome commonly causes pain on the outside of the knee. It may develop during longer runs or become more noticeable when running downhill.
The iliotibial band is a strong band of connective tissue that runs along the outside of the thigh from the hip toward the knee.
What causes it?
IT band symptoms are often associated with repetitive running loads and may be influenced by training changes, hip and leg strength, and how the body tolerates repeated movement.
Contributing factors can include:
Rapid increases in mileage.
Repeated downhill running.
Insufficient recovery.
Strength or movement-control limitations that need to be assessed individually.
How to treat it:
Modify running activities that reproduce the pain and gradually return to training as symptoms improve. Rehabilitation may involve strengthening the hip and leg muscles, managing training loads, and addressing relevant mobility or movement limitations.
If pain persists, seek professional evaluation rather than relying on foam rolling alone.
How to help prevent it:
A balanced strength program may include step-downs, split squats, single-leg exercises, and progressive hip strengthening.
However, there is no single exercise or movement correction that prevents IT band syndrome in every runner. The key is to identify what your body needs and build your training around it.
The Common Denominator: How You Train Matters
Although these injuries affect different parts of the body, a common theme is that training demands can exceed the body's current ability to tolerate them.
Running more isn't always the answer. Sometimes the best way to become a better runner is to spend time improving the strength, mobility, and movement capacity that support your running.
Here are five principles I recommend incorporating into your routine:
1. Strength train consistently.
Running develops endurance, but a well-designed strength program can help improve muscular capacity and support performance. Focus on the lower body, hips, calves, core, and single-leg control.
2. Increase mileage gradually.
Avoid making large increases in distance, speed, hills, and workout frequency all at once. There is no universal mileage progression that guarantees injury prevention, so adjust your training to your experience, recovery, and symptoms.
3. Improve mobility where needed.
Restricted movement may affect how comfortable or efficient an exercise feels, but more flexibility isn't automatically better. Assess your individual needs instead of stretching everything indiscriminately.
4. Prioritize recovery.
Sleep, appropriate nutrition, rest days, and sensible scheduling help you adapt to training. More work isn't always better if your body cannot recover from it.
5. Pay attention to warning signs.
Don't ignore pain that worsens as you run, changes your stride, persists at rest, or interferes with daily activities. Seek medical evaluation when appropriate.
How Training With Me Can Help You Become a Stronger, More Resilient Runner
My training philosophy is built around one principle: your body should be prepared for the demands you place on it.
With over 28 years in the fitness industry and credentials in personal training, corrective exercise, and performance enhancement, I work with clients to improve strength, movement quality, flexibility, and overall performance.
My approach starts with understanding how your body moves and what you want to accomplish.
Depending on your needs, your program may include:
Postural and movement assessments: Identify movement patterns and areas that may benefit from further attention.
Customized strength training: Build lower-body, hip, calf, and core strength to support your running goals.
Mobility and flexibility work: Address relevant restrictions that may affect your training.
Balance and stability exercises: Develop control during single-leg movements and other running-related tasks.
Progressive programming: Match your workouts to your current fitness level, schedule, and goals.
Nutrition and recovery guidance: Support your training with practical habits that help you stay consistent.
Every runner is different. A beginner building up to their first 5K has different needs from a marathon runner trying to improve their pace or someone returning to exercise after time away.
That's why I don't believe in a one-size-fits-all program.
My goal is to help you develop the strength and physical capacity to train more effectively, improve your performance, and reduce modifiable injury risks.
Important: Personal training can support general conditioning and injury-risk reduction, but it is not a substitute for medical diagnosis or injury rehabilitation. If you're currently injured, work with an appropriate healthcare professional to determine when and how to resume training.
