Quick Answer
Most running injuries are caused by doing too much too soon, not enough strength work, and insufficient recovery. The best prevention is gradual training progression, two strength sessions per week, proper rest days, and listening to your body before small niggles become serious problems.The Most Common Running Injuries and Why They Happen
Almost all running injuries are overuse injuries. They develop gradually over days or weeks rather than from a single event. The common thread is that the load placed on a tissue exceeds its capacity to recover and adapt.
Here are the injuries that account for the majority of time lost from running:

| Injury | Where It Hurts | Common Cause |
|---|---|---|
| Achilles tendinopathy | Back of the ankle, above the heel | Sudden increase in volume or speed, weak calves, low-drop shoes |
| Shin splints | Inner or front of the shin bone | Rapid mileage increase, hard surfaces, low cadence |
| Runner's knee | Around or behind the kneecap | Weak glutes and quads, overstriding, too much downhill |
| Plantar fasciitis | Underside of the heel, worst in the morning | Tight calves, high training volume, unsupportive footwear |
| IT band syndrome | Outside of the knee | Weak hip stabilisers, sudden mileage increase, cambered roads |
| Hip flexor strain | Front of the hip or upper thigh | Too much speed work, prolonged sitting, tight hip flexors |
| Calf strain | Back of the lower leg | Weak calves, speed sessions without adequate warm-up |
Notice the pattern. Almost every injury on this list comes back to three things: training load that increases too quickly, muscles that are not strong enough to handle the demands of running, and not enough recovery between sessions.
Achilles Pain and Running — Causes and Solutions
The achilles tendon connects your calf muscles to your heel bone and absorbs enormous force with every stride. When you run, the achilles handles loads of up to eight times your body weight. When the tendon is loaded beyond its current capacity, it becomes irritated and painful.
Symptoms: stiffness or pain at the back of the ankle, especially first thing in the morning or at the start of a run. It may warm up and feel better during the run, then stiffen again afterwards. In more advanced cases, the tendon may feel thickened or nodular.
Common causes: a sudden increase in running volume or intensity, adding hill sessions or speed work too quickly, switching to shoes with a lower heel-to-toe drop, and weak calf muscles.
What to do: reduce your running volume but do not stop completely unless pain is severe. Eccentric calf raises, where you slowly lower your heel off a step, are one of the most evidence-based treatments for achilles tendinopathy. Start with three sets of 15, twice daily, and build gradually. For a detailed protocol, read our guide to Alfredson’s eccentric heel drop protocol.
When to see a physio: If pain has been present for more than two weeks without improvement, book in with a physiotherapist or sports physio. In Australia, you can see a physio without a GP referral — most other countries have similar direct access.
Shin Splints — How to Run Without Pain
Shin splints, or medial tibial stress syndrome, cause pain along the inner or front edge of the shin bone. They are one of the most common injuries in new runners and in experienced runners who increase their mileage too quickly.
Symptoms: a dull, aching pain along the shin that appears during running and may ease afterwards. In early stages it often warms up and feels better as the run continues. If ignored, it can progress to pain that persists during walking and at rest.
Common causes: rapid increases in weekly mileage, running on hard surfaces like concrete, a low running cadence that leads to overstriding, and weak calf and tibial muscles. For a deeper look at how tibia loading affects runners, read our tibia pain guide.
What to do: reduce your mileage to a level that does not cause pain, then rebuild gradually. Increasing your running cadence by 5 to 10 percent can reduce impact forces on the shin. Calf raises, toe raises, and single-leg balance work strengthen the muscles that support the tibia. Running on softer surfaces like grass or trails while you recover also helps.
When to see a physio: if shin pain becomes sharp and localised to one spot rather than spread along the bone, you may have a stress fracture rather than shin splints. This requires medical assessment and imaging.
Runner's Knee and Knee Pain
Runner’s knee, or patellofemoral pain syndrome, is pain around or behind the kneecap. It is the single most common running injury and affects runners at every level.
Symptoms: a dull ache around the front of the knee, especially when running downhill, climbing stairs, or sitting with bent knees for extended periods. It often worsens during longer runs or after sitting still.
Common causes: weak gluteal muscles that fail to stabilise the pelvis, weak quadriceps, overstriding, and sudden increases in training volume or intensity. IT band syndrome, which causes pain on the outside of the knee, is closely related and often driven by weak hip stabilisers.
What to do: strengthen your glutes and quads with exercises like squats, lunges, single-leg squats, and glute bridges. Reduce your training volume temporarily and avoid excessive downhill running while the pain settles. Shortening your stride and increasing your cadence can also reduce the load on the kneecap.
Plantar Fasciitis and Running
Plantar fasciitis is inflammation or degeneration of the plantar fascia, the thick band of tissue that runs along the bottom of your foot from heel to toes. It is one of the most stubborn running injuries because the foot is loaded with every step you take, even when you are not running.
Symptoms: sharp pain under the heel, particularly with the first steps in the morning. It may ease as you move around, then return after long periods of standing or at the start of a run. For more detail on heel and arch pain patterns, read our guides on heel pain after running and sore arches after running.
Common causes: tight calf muscles that increase strain on the plantar fascia, a rapid increase in running volume, unsupportive footwear or worn-out running shoes, and spending long hours standing on hard surfaces.
What to do: calf stretching and rolling a frozen water bottle under the foot can provide relief. Strengthening the intrinsic muscles of the foot with exercises like toe curls and foot domes helps build the fascia’s capacity. Ensure your running shoes are not worn out and provide adequate support for your foot type. Night splints can reduce morning pain by keeping the fascia gently stretched overnight.
Hip and Calf Pain for Runners
Hip pain in runners most commonly comes from hip flexor strain or gluteal tendinopathy. Hip flexor strain is often caused by too much speed work or hill running combined with tight hip flexors from prolonged sitting. Gluteal tendinopathy causes pain on the outside of the hip and is common in runners who cross-train with activities that involve lateral movement.
The fix for most hip pain starts with strengthening the glutes and improving hip flexor flexibility. Single-leg exercises like step-ups, single-leg deadlifts, and side-lying leg raises are particularly effective. If hip pain persists beyond two weeks or affects your gait, see a physiotherapist.
Calf pain during running is often caused by calf muscle weakness relative to the demands of running. Your calves absorb and produce enormous forces with every stride, and they fatigue quickly when undertrained. Sudden increases in speed work, hill running, or total mileage are the most common triggers.
Progressive calf strengthening with both straight-leg and bent-knee calf raises is the most effective prevention and treatment. Start with bodyweight and build to weighted exercises over time. For a deeper look at calf pain management, read our ankle and lower leg pain guide.
How to Prevent Running Injuries Before They Start
Prevention is always easier than treatment. These five habits cover the vast majority of what you can do to stay injury-free.
Manage your training load. The 10 percent rule, where you increase weekly mileage by no more than 10 percent, is a useful guideline. More importantly, avoid adding volume and intensity at the same time. If you are increasing your long run, keep your other runs easy. If you are adding speed work, hold your total mileage steady.
Do strength work twice a week. Fifteen to twenty minutes of squats, lunges, calf raises, glute bridges, and planks is enough to dramatically reduce your injury risk. Runners who do regular strength training have significantly fewer injuries than those who only run.
Respect your rest days. Your body adapts and gets stronger during rest, not during the run itself. Two to three rest or active recovery days per week is essential for most recreational runners. Heart rate zone training can help ensure your easy days are genuinely easy.
Improve your running form. Overstriding, low cadence, and excessive vertical bounce all increase impact forces. Increasing your cadence by 5 to 10 percent and landing with your foot closer to your centre of mass reduces stress on your joints. Read more in our running cadence and technique guide.
Warm up properly. Five minutes of brisk walking followed by dynamic stretches like leg swings, high knees, and hip circles prepares your muscles and tendons for running. Save static stretching for after your run. A proper cool-down routine after running also supports recovery.
Coach’s tip: Most running injuries do not come from one bad session. They build up over weeks of slightly too much load without enough recovery. A running coach monitors your training load week by week and catches these patterns before they become injuries. Prevention is what coaching does best.
Return to Running After Injury
Coming back from injury is where many runners make their second mistake. The first mistake caused the injury. The second is returning too quickly and getting injured again.
A structured return to running program follows these principles:
Start with walk/run intervals. Even if you feel fine, your muscles, tendons, and bones need time to readapt to running impact. Begin with short running intervals separated by walking breaks, just like a Couch to 5K plan. Gradually increase running time and decrease walking time over two to four weeks.
Follow the pain rules. Pain below 3 out of 10 during a run is generally acceptable. Pain that increases during a run, changes from dull to sharp, or lingers into the next day means you have done too much. Scale back and progress more slowly.
Rebuild mileage before intensity. Get your weekly volume back to pre-injury levels at easy pace before adding any speed work, hills, or races. Intensity is the last thing to return.
Continue your rehab exercises. The strength work that helped you recover from injury should become a permanent part of your routine. Stopping it once you feel better is the fastest way to get injured again.
Be patient. A four-week injury with a four-week return to running is far better than a two-week rest followed by a relapse that costs you three months. Patience is not passive. It is strategic.
How Coaching Prevents Running Injuries
A running coach does not just write training plans. The most valuable thing a coach does is manage your training load so that you progress consistently without crossing the line into injury.
Load management. Every week, your coach reviews how your body responded to training and adjusts the following week accordingly. If you are fatigued, volume drops. If you are flying, progression continues. This adaptive approach is fundamentally different from following a static plan that does not respond to how you feel.
Technique correction. Overstriding, low cadence, and poor posture are injury risk factors that a coach identifies and addresses through specific drills and cues. Small form changes can significantly reduce the forces on vulnerable structures like the achilles, knees, and shins.
Personalised progression. A generic plan progresses at the same rate for everyone. A coach progresses you at the rate your body can handle, which depends on your age, training history, injury history, and how much stress you are dealing with outside of running.
Early intervention. When a niggle appears, a coach adjusts your plan immediately rather than waiting to see if it gets worse. This single habit prevents more injuries than any amount of stretching or foam rolling.
Most running injuries are preventable with the right training structure. At SportCoaching, we work with runners across Australia and internationally — from first-timers recovering from shin splints to experienced marathoners managing chronic achilles issues.

Get Expert Running CoachingFAQ: Running Injury Prevention
What is the most common running injury?
Runner’s knee, or patellofemoral pain syndrome, is the most frequently reported running injury. It causes pain around the front of the knee and is most often caused by weak glutes and quads combined with overstriding or too much training volume.
How do I know if I should stop running or run through pain?
Mild muscle soreness that improves as you warm up is generally fine to run through. Sharp pain, pain that gets worse during a run, pain that changes your gait, or pain that lingers into the next day are all signals to stop and rest. When in doubt, take an extra rest day rather than pushing through.
How long does it take to come back from a running injury?
It depends on the injury and how quickly you addressed it. Most minor overuse injuries resolve in two to four weeks with reduced training and targeted rehab. More serious injuries like stress fractures or chronic tendinopathy can take two to six months. The earlier you respond to warning signs, the shorter your time away from running.
Does stretching prevent running injuries?
Static stretching before running has not been shown to prevent injuries and may even reduce performance. Dynamic warm-ups before running and static stretching after running are more effective. Strength training has far more evidence behind it as an injury prevention tool than stretching alone.
Can a running coach help prevent injuries?
Yes. A coach manages your training load, monitors how your body responds each week, adjusts your plan when warning signs appear, and builds in the right amount of strength work and recovery. Runners who train with a coach typically experience fewer injuries because their training is structured and adaptive rather than random.
