Running injuries cut across every level of runner, from those heading out for the first time to those with years of training behind them. The sport asks a lot of the body. Each stride travels force through the feet, ankles, shins, knees, and hips, and when that force is not managed well, the result is pain that sidelines you. How you respond in those first hours shapes how quickly you recover. With the right response, most running injuries are manageable, and many are avoidable.
Runner's Knee
Runner’s knee is the most common overuse injury, meaning it develops from repetitive stress rather than a single incident, and it accounts for around a quarter of all running-related injuries. It develops when the kneecap, which normally slides up and down along a groove in the thigh bone as you bend your knee, rubs against the bone instead of gliding smoothly through it. This happens when the muscles around the knee are under more strain than they can handle, and the result is a dull ache around or behind the kneecap that gets worse with stair climbing, squatting, and sitting with bent knees for long periods.
Strains and Sprains: Groin, Calf, Achilles Tendon, and Hamstring Injuries
Strains and sprains are some of the most common running injuries. A strain is a stretch or tear of a muscle or tendon; a sprain is a stretch or tear of a ligament.
Strains happen when a muscle or tendon is loaded beyond what it can handle, and the groin, calf, and hamstring are all vulnerable. They tend to announce themselves with a sudden sharp pain or pop at the moment of injury, and the muscle becomes painful to use immediately after. The Achilles tendon is an exception, with strains building gradually from repeated overload rather than a single incident.
Sprains happen when a joint is forced out of its normal range and the ligaments holding it in place are stretched or torn. The ankle is the most common site for runners and the injury is usually obvious: the joint gives way, swells quickly, and is painful to put weight on.
Iliotibial Band Syndrome
The iliotibial band is a thick strip of connective tissue that runs from the hip down the outside of the thigh to the knee. It can rub against the bone beneath it with each step and become inflamed, causing a sharp or burning pain on the outside of the knee that builds gradually. Unlike many knee injuries, iliotibial band syndrome does not involve the knee joint itself.
Iliotibial band syndrome affects up to 22 per cent of distance runners. It develops from a combination of factors including high mileage, running on sloped or banked surfaces, and weak hip muscles that fail to keep the pelvis stable through each step.
Shin Splints
Shin splints are one of the most common running injuries in people new to the sport or returning after a break. The term describes shin pain along the inside of the tibia caused by inflammation of the surrounding tissue and bone. The pain tends to be a dull ache and is spread across the lower leg rather than concentrated at a single point.
Shin splints develop when the lower leg is placed under repetitive stress it is not yet ready to handle. This can happen when training is increased too quickly, when runs are done on hard surfaces like concrete, or when worn shoes fail to adequately absorb impact.
Stress Fractures
Stress fractures are tiny cracks in bone caused by repetitive impact over time, and they are among the more serious running injuries. The pain from a stress fracture is localised to a specific point on the bone, worsens consistently with activity, and can persist at rest.
These injuries occur when bone is subjected to more pressure than it can repair between training sessions. Risk is increased by a sudden spike in running volume, running on hard surfaces, inadequate intake of calcium and vitamin D, and returning to training too quickly after illness or time off.
Aches and Pain
Not all discomfort during or after running signals a running injury. General muscle aches, joint stiffness, and post-run soreness are a normal part of training, particularly when increasing mileage or returning after time off. Pain that is localised, persistent, or getting sharper over time is the body signalling that something needs attention.
Delayed onset muscle soreness (DOMS) is a common example, producing general aching and tenderness in the muscles that peaks 24 to 48 hours after the session. It is a normal response to increased training and resolves without treatment within a few days.
Runner First Aid Steps
When a running injury affects soft tissue, the recommended approach is PEACE & LOVE, which covers both the immediate management over the first few days and the long term recovery that follows. In the first one to three days, only PEACE applies:
Protect. Stop the activity and limit any movement that causes pain. Rest, but not completely or for longer than three days.
Elevate. Raise the injured area above heart level to reduce swelling.
Avoid anti-inflammatories and ice. Inflammation is part of the body’s natural healing process. Anti-inflammatory medication and ice can slow tissue repair.
Compress. Apply a compression bandage to the injured area to limit swelling. Start below the injury and wrap upward, overlapping each layer by half. The bandage should feel snug but not tight enough to restrict circulation.
Educate. See a doctor to understand what the injury is, how serious it is, and what recovery looks like for your specific situation.
How to Prevent Injury
Running injuries are largely preventable. Preventing them mostly comes down to training and equipment that you can address directly.
Increase volume gradually. Add no more than 10 percent to your total distance from one week to the next.
Warm up and cool down. Begin each session with five to ten minutes of brisk walking or easy jogging before picking up pace. After running, stretch your calves, hamstrings, quadriceps, hip flexors, and iliotibial band while the muscles are still warm.
Wear the right footwear. Replace your shoes every 500 to 800 kilometres, or when the sole begins to compress visibly or tread wear becomes uneven.
Cross-train and rest. Alternating between running and low-impact exercise such as swimming or cycling reduces the repetitive stress placed on specific tissue. Schedule at least one full rest day per week.
See a physiotherapist. A physiotherapist can help you identify movement problems, muscle imbalances, and technique issues before they become running injuries.
Learn First Aid for Common Running Injuries
Running injuries may be common, but they are also identifiable, treatable, and preventable. A minor injury that is handled well stays minor, and first aid training can give you the skills and knowledge to keep it that way. Enrol in a first aid course with and go into every run ready to respond.
FAQs
What Is Patellofemoral Pain Syndrome?
Patellofemoral pain syndrome (PFPS) is the clinical name for runner’s knee.
When Should I See a Doctor About a Running Injury?
See a doctor if the pain is severe, if you cannot bear weight on the injured limb, if there is significant swelling or bruising, or if the pain does not improve after a few days of rest. Localised bone pain that worsens with each run warrants medical assessment to rule out a stress fracture. Any injury that keeps returning despite rest and self-treatment also needs evaluation.
How Soon After a Soft Tissue Injury Can I Return to Running?
Mild muscle strains may allow a return to running within one to two weeks once pain has fully resolved. Moderate strains can take three to six weeks, while severe strains or significant ligament sprains may require eight to twelve weeks or longer.
