Addressing The Most Common Running-Related Leg Injuries
As a certified strength and conditioning coach with years of experience, I know that some mild soreness after a run is perfectly normal. It’s a sign your muscles are adapting. But when that soreness sticks around, gets worse, or becomes a sharp pain, you’re likely dealing with one of the most common running-related leg injuries.
The good news is that most of these issues are easy to diagnose and treat.
Prevention is always the best strategy, and simple tools can make a huge difference. Ankle braces and knee braces provide an optimal combination of protection and mobility, but finding the right balance depends entirely on your individual needs.

Key Takeaways
- Listen to Your Body: Differentiate between normal post-run soreness and persistent pain, which signals a potential injury.
- Master the RICE Method: For acute injuries like sprains, immediately apply Rest, Ice, Compression, and Elevation to manage swelling and kickstart healing.
- Focus on Prevention: The most effective way to handle running injuries is to avoid them. This involves proper stretching, strengthening supporting muscles (especially glutes and hips), and using appropriate footwear and orthotic aids when needed.
- Don’t Rush Recovery: Returning to your running routine before an injury is fully healed is a common mistake that can lead to chronic issues and much longer recovery times.
Ankle Injuries
Sprained ankles are the most common of ankle injuries for runners. The vast majority of these are inversion sprains, which impact the anterior talofibular ligament (ATL). Research from the National Library of Medicine confirms that this ligament is the most frequently injured in the ankle, accounting for a significant number of cases.
This injury happens when your ankle rolls inward as you land, placing too much stress on the ATL on the outside of your ankle. The primary symptoms are immediate pain, swelling, and inflammation right over that area.
For mild sprains, you can typically see improvement within one to three weeks, especially if you diligently use the RICE method.
- Rest: Stay off the ankle as much as possible. Use crutches or a protective boot to keep it immobilized and avoid bearing weight.
- Ice: Apply a cold pack for 15 to 20 minutes at a time, every two to three hours. Never place ice directly on the skin, and wait at least 20 minutes between sessions to prevent tissue damage.
- Compression: Use an Ace bandage, compression sleeve, or kinesiology tape like KT Tape to help reduce swelling. This also provides crucial support to the joint as the ligament heals.
- Elevation: Keep your ankle raised above the level of your heart as often as you can. Be sure to lower it periodically to maintain healthy circulation.
A common mistake I see athletes make is returning to their sport too soon. You must ensure the ankle is completely healed before you resume running. Ankle sprains are highly susceptible to re-injury, and a second injury is always harder to rehabilitate.
Knee Injuries
While a single misstep often causes ankle injuries, knee injuries in runners usually develop over time from a mix of overuse and poor running mechanics. The most notorious of these is Patellofemoral Pain Syndrome (PFPS), better known as “runner’s knee.”
PFPS is so common it accounts for up to 25% of all running-related injuries, according to some studies. It occurs when the patella, or kneecap, doesn’t track correctly in the femoral groove of your thigh bone, causing pain behind or around the kneecap. Some people are more predisposed to this due to their anatomy.
If you feel that tell-tale ache in your kneecap, your first step is to dramatically reduce your mileage. The RICE method will help with the immediate pain and inflammation. As the pain subsides, you can gradually increase your distance.
More importantly, you need to address the cause. Focus on your running form. Try taking shorter, quicker steps, aiming for a cadence of around 170-180 steps per minute, which can reduce impact forces on the knee. Also, ensure you wear well-cushioned, supportive shoes from brands known for stability, like Brooks or HOKA.
If the pain continues, rehab might be needed to strengthen the muscles that support the knee, like the quadriceps and hip abductors.
More Common Leg Injuries in Runners
Beyond the ankle and knee, several other leg injuries frequently affect runners. Understanding them is key to effective treatment and prevention.
Hamstring Strain
That final sprint to the finish can sometimes lead to a hamstring injury, one of the most common muscular leg injuries. The hamstring is a group of three muscles at the back of your thigh. They can get strained when they’re overstretched or overloaded, especially if your glute muscles aren’t strong enough to do their share of the work.
Runners who don’t warm up or stretch properly are at a higher risk. In my experience as a trainer, underdeveloped glutes are a primary culprit. When your glutes are weak, your hamstrings have to overcompensate, leading to fatigue and injury.
Shin Splints (Medial Tibial Stress Syndrome)
Shin splints cause a nagging pain along the inner edge of your shinbone. This is an overuse injury, often triggered by a sudden increase in training intensity or duration. It’s particularly common in newer runners or those returning after a break.
Key contributors include improper footwear that doesn’t provide enough support and overpronation, where your foot rolls inward excessively. Treatment involves rest and icing the affected area. Many runners find relief by using a foam roller, like the TriggerPoint GRID, on their calf muscles to relieve tightness. Once the pain is gone, focus on calf-strengthening exercises like calf raises.
Achilles Tendinitis
The Achilles tendon is the large tendon connecting your calf muscles to your heel bone. Achilles tendinitis is inflammation of this tendon from overuse. It creates pain and stiffness at the back of the heel, which is often most pronounced in the morning.
Tight calf muscles are a major risk factor. A proven and effective treatment that I recommend to clients is performing eccentric heel drops. You stand on the edge of a step, rise up on both toes, then slowly lower one heel down below the level of the step. This controlled lengthening of the tendon helps promote healing.
The RICE method, proper stretching, and strong supporting muscles are the keys to preventing or treating most of these common leg injuries. Running can be a source of lifelong fitness and health. If you treat your body right, it will carry you for many miles to come.

Frequently Asked Questions (FAQs)
How can I tell the difference between normal soreness and an injury?
Normal muscle soreness, or Delayed Onset Muscle Soreness (DOMS), feels like a general ache, peaks 24-48 hours after a workout, and improves with light activity. An injury often involves sharp, localized pain that worsens with activity and doesn’t go away with rest.
What are the best running shoes to prevent injuries?
There is no single “best” shoe. The right choice depends on your foot type, running gait, and comfort. I advise getting a professional gait analysis at a specialty running store. They can recommend shoes with the right level of support and cushioning, such as stability shoes for overpronation or neutral shoes for a normal gait.
Should I use heat or ice for running leg injuries?
For the first 48-72 hours after an acute injury (like an ankle sprain), use ice to reduce inflammation and numb pain. After that initial period, or for chronic muscle tightness, you can use heat to increase blood flow and relax the muscles.
When should I see a doctor for a running injury?
You should see a doctor or physical therapist if you experience severe pain, swelling, or numbness. Also seek medical advice if the pain doesn’t improve after a week of self-care with the RICE method, or if you’re unable to bear weight on the affected leg.
