Back Pain After Running: Why It Happens, Causes & How to Fix It

Running is one of the simplest ways to improve cardiovascular fitness, stamina, bone health, mood, and overall physical function.

So when your lower back starts aching after a run, it can be confusing:

Should you stop running? Is your running form wrong? Could your shoes be responsible? Or does back pain after running mean something is wrong with your spine?

The reassuring answer is that running itself is not automatically harmful to your back.

In fact, research suggests that low back pain is relatively uncommon among runners compared with many other running-related injuries.

A systematic review of 19 studies found reported low-back-pain prevalence among runners ranging from 0.7% to 20.2%, with several potentially modifiable factors including restricted hip movement, flexibility limitations and differences in leg length.

However, pain that repeatedly appears after running deserves attention.

From a physiotherapy perspective, I would not immediately blame your shoes, your posture, your spine, or your running surface.

Back pain after running is usually a load-management and movement-capacity problem rather than a single “bad posture” problem.

Your back is working with your hips, pelvis, abdominal muscles, gluteal muscles and legs every time your foot strikes the ground.

If one part of this system cannot tolerate the workload, another region may compensate.

Let’s look at what may actually be happening.

Why does my back hurt after running?

The first important distinction is when the pain begins.

If your back hurts while running, we think differently about it than if you finish your run feeling fine and develop soreness several hours later.

Pain that develops during a run may be associated with repeated loading, fatigue, movement sensitivity, or an existing musculoskeletal problem.

Pain that appears later may simply reflect a workload that exceeded your current capacity.

This is why two people can run exactly the same distance but have completely different responses.

A runner who comfortably handles 10 km may recover easily, while someone returning after three months away may develop back soreness after 4 km.

The problem is not necessarily that 4 km is “bad” for the back.

It may simply be too much for that person’s current capacity.

Research on running injuries supports the idea that injury risk is multifactorial.

A 2024 umbrella systematic review found that training characteristics, health and lifestyle factors, morphological factors and biomechanical factors can all contribute to running-related injury risk,

although the authors also emphasized that the quality of existing evidence varies considerably. (Elsevier)

Your weekly running load may have changed too quickly

One of the most overlooked causes of back pain after running is not running technique at all.

It is what changed recently.

Think about the previous two to four weeks:

• Did you increase your distance?
• Did you add hill running?
• Did you start interval training?
• Did you increase your running days?
• Did you suddenly start preparing for a 10K or half marathon?
• Did you return to running after a break?
• Did you add strength training at the same time?

Your body adapts to stress progressively.

A systematic review investigating changes in training load found that several studies linked increases in training load with greater running-injury risk,

although the evidence did not establish one universal percentage that is safe for everyone. (Journal of Athletic Training)

This is important because the popular “increase your running by exactly 10% every week” rule is not a universal scientific law.

Instead, I prefer a more individualized approach: increase one major training variable at a time and give your body enough recovery to adapt.

Your hip may not be moving efficiently

Your lumbar spine does not operate independently during running.

Your hip needs to extend behind you, flex forward, rotate and absorb forces while your pelvis remains sufficiently controlled.

If hip movement is restricted, your lumbar spine may contribute more movement than it ideally should.

Interestingly, the systematic review specifically examining low back pain in runners identified restricted hip flexion range of motion as one of the reported risk factors.

It also identified factors such as hamstring and back flexibility, although these findings should not be interpreted as proof that tight muscles directly cause pain.

This distinction matters.

A tight muscle is not automatically an injured muscle.

And stretching every muscle that feels tight is not necessarily the solution.

Sometimes the better intervention is improving hip strength, movement coordination and tolerance to running.

Your core may not be “weak” in the way you think

I often see runners respond to back pain by doing hundreds of crunches.

That may not address the actual problem.

During running, your trunk needs to transfer force between your arms and legs while controlling excessive movement.

Your core therefore needs endurance, coordination and the ability to resist unwanted motion, not simply the ability to perform a high number of sit-ups.

A runner who can hold a plank for two minutes can still struggle to maintain trunk control during the final kilometres of a race.

Why?

Because running is repetitive.

One running stride may not challenge your trunk significantly.

Thousands of strides performed while fatigued are different.

This is why physiotherapy assessment should look at capacity under fatigue, rather than simply asking whether you can perform one isolated exercise.

Glute weakness can contribute, but don’t blame your glutes automatically

“Your glutes are weak” has become almost a universal explanation for running injuries.

Reality is more complicated.

Your gluteal muscles certainly contribute to hip extension, pelvic control and force production.

But research does not support the idea that one isolated weakness test can explain every running injury.

A systematic review and meta-analysis of biomechanical and musculoskeletal measurements in non-elite runners found relatively few consistent relationships between individual biomechanical variables and future running injury. (Springer Link)

That means your physiotherapist should not simply test your glute strength, declare it “weak,” and stop there.

We need to ask:

Can your entire lower-body system tolerate the demands of your running?

That is a much more useful question.

Running hills can expose a problem you don’t notice on flat ground

Hill running changes the mechanical and muscular demands of running.

Uphill running generally requires greater muscular effort, while downhill running can increase braking demands.

If your back pain appeared after you recently added hills, do not assume that your spine suddenly became damaged.

Your body may simply be responding to a new stimulus.

Try temporarily reducing hill volume while maintaining comfortable flat running, then gradually reintroduce hills.

A useful physiotherapy principle is:

Modify the aggravating load, not necessarily all activity.

That distinction can prevent the common cycle of complete rest followed by an aggressive return to running.

Fatigue can change your running mechanics

Your running form at kilometre 2 may not look like your running form at kilometre 10.

As fatigue increases, stride characteristics, trunk position, pelvic control and muscle recruitment can change.

This is one reason I am cautious about telling runners to simply “fix their posture.”

There is no single perfect running posture.

Your body naturally varies movement from stride to stride.

Research examining running biomechanics and injury risk has found that biomechanical relationships are complex rather than reducible to one universally harmful movement pattern. (BMJ Open)

Instead of obsessively trying to keep your back perfectly straight, focus on whether you can maintain comfortable, efficient movement as fatigue develops.

Could your running shoes be causing back pain?

Possibly, but don’t blame your shoes first.

A new pair of shoes can change how running feels, particularly if the shoe differs substantially in cushioning, heel-to-toe geometry, stiffness or fit.

But there is no single “best running shoe for back pain” that works for everyone.

If your pain began immediately after changing shoes, however, that is useful information.

Rather than buying another pair immediately, compare:

• old versus new shoes
• running distance in each
• pain during and after running
• terrain
• pace
• hill exposure
• recovery between sessions

The combination gives you much more useful information than the shoe label.

Can running damage your spinal discs?

This is one of the biggest fears runners have.

The answer is more nuanced than “running damages discs.”

A recent systematic review examining the effects of running on intervertebral discs found evidence across studies looking at disc morphology and composition,

but the relationship between running and disc health is complex and should not be reduced to the idea that every impact is harmful. (Sports Health)

Your spine is designed to experience loading.

Exercise creates mechanical stress, but mechanical stress is not synonymous with damage.

In healthy tissues, appropriately dosed loading can be part of adaptation.

Therefore, feeling back soreness after running does not automatically mean that you have worn out your discs.

Why does my lower back hurt after running but not walking?

Running produces substantially different demands from walking.

There is a flight phase during running, greater loading rates and greater muscular requirements.

Your trunk and pelvis also need to coordinate rapidly with your lower limbs.

If walking is completely comfortable but running triggers symptoms, it may indicate that your current capacity for higher-speed or repetitive loading is lower than your walking capacity.

That does not necessarily mean you should stop exercising.

It may mean you need to temporarily bridge the gap between walking and running.

For example:

Walking → brisk walking → walk-jog intervals → easy continuous running → longer running → faster running

This graded approach can be particularly useful after injury or a prolonged break.

Is running good or bad for people with back pain?

For most people, the answer is not simply “good” or “bad.”

Movement should be individualized.

The World Health Organization’s 2023 guideline for chronic primary low back pain recommends non-surgical management that can include education, exercise and other appropriate interventions, with care tailored to the individual’s circumstances. (PMC)

Structured exercise is specifically recommended as an option, although the certainty of evidence varies.

For an active person, the goal should therefore often be restoring the ability to do meaningful activities, rather than eliminating every sensation before returning to movement.

What should I do if my back hurts after running?

First, reduce the provoking dose

You do not necessarily need complete bed rest.

If your usual 8 km run causes significant pain, experiment with a lower dose.

For example, you might temporarily switch to:

• shorter easy runs
• run-walk intervals
• flatter routes
• slower pace
• fewer running days
• cycling or walking for cardiovascular training

The goal is to find a level that your back tolerates.

Use symptoms as information, not as a scorecard

I prefer runners to monitor three things:

During exercise: Does the pain increase progressively?

Immediately afterward: Can you move normally?

The next morning: Has your baseline pain clearly worsened?

The next-morning response can be particularly useful when deciding whether your previous session was appropriately dosed.

If every run leaves you significantly worse the following day, your training load probably needs modification.

Build strength alongside running

Strength training is not merely rehabilitation for injured runners.

It can also improve running performance.

A 2024 systematic review and meta-analysis found that several forms of strength training, particularly higher-load and plyometric approaches, can improve running economy in middle- and long-distance runners. (Springer)

For a runner dealing with back discomfort, a physiotherapist may select exercises such as:

• hip hinges
• Romanian deadlifts
• split squats
• step-ups
• calf raises
• side planks
• bird dogs
• controlled trunk exercises
• loaded carries

The exact exercises should depend on your symptoms, strength and running goals.

You do not need to perform every “runner’s exercise” on the internet.

Train your hips, but don’t forget your calves

A lesser-known point is that running capacity depends on the entire kinetic chain.

The calf and ankle complex contributes significantly to propulsion and shock management.

If your calves fatigue quickly, other regions may alter their contribution.

This does not mean calf weakness automatically causes back pain.

Rather, it illustrates why a physiotherapy assessment should not stop at the lumbar spine.

Your therapist may examine:

foot → ankle → calf → knee → hip → pelvis → trunk

rather than treating your back as an isolated body part.

Should you stretch before running?

Not necessarily.

A long series of static stretches is not mandatory before every run.

Instead, a dynamic warm-up may be more practical for many runners.

Try five to ten minutes of easy movement followed by exercises such as:

• marching
• walking lunges
• controlled leg swings
• calf raises
• hip mobility movements
• gradual jogging

If a particular mobility restriction clearly affects your running, targeted stretching can be included.

But stretching should have a purpose.

Don’t stretch simply because your back hurts.

Can changing your running cadence reduce back pain?

Cadence is an interesting area, but it should not become another rigid rule.

Some runners naturally use a relatively low step rate, while others have a higher cadence.

Increasing cadence slightly can alter stride characteristics and loading patterns in certain runners.

Gait retraining has been studied as a strategy for changing running biomechanics, pain and injury outcomes, although the evidence is not strong enough to prescribe one cadence for everyone.

If your physiotherapist identifies excessive overstriding or a cadence-related movement issue, a small individualized adjustment may be worth testing.

Don’t suddenly force yourself to run at 180 steps per minute because an online video told you that it is the “perfect cadence.”

There isn’t one perfect number.

When should you stop running?

Stop the run and seek professional assessment if the pain is severe, rapidly worsening, or accompanied by neurological symptoms.

You should also seek medical evaluation if you develop:

• pain travelling strongly down the leg
• progressive leg weakness
• significant numbness
• loss of coordination
• new bowel or bladder problems
• numbness around the groin or saddle region
• unexplained fever
• unexplained weight loss
• significant pain after major trauma
• severe night pain that is unusual for you

These symptoms require more than a home exercise program.

When should you see a physiotherapist?

Consider seeing a physiotherapist if your back pain:

• repeatedly returns after running
• lasts beyond the expected recovery period
• limits your running distance
• causes you to change your movement
• is associated with leg symptoms
• keeps returning despite reducing your mileage
• prevents you from progressing your training

A good running-focused physiotherapy assessment may examine much more than your lower back.

Your therapist may assess spinal movement, hip mobility, hip and leg strength, single-leg control, calf capacity, running tolerance, training history, recovery, footwear and running technique.

The objective is not to find one “broken” body part.

It is to identify which demands currently exceed your capacity.

A physiotherapist’s simple return-to-running strategy

If your pain is mild and you have no red flags, a gradual approach may be more appropriate than stopping indefinitely.

Start with a comfortable running dose.

Then progress one variable at a time.

For example:

Week-to-week progression might involve increasing duration first, then distance, and only later introducing hills or speed.

Don’t increase everything simultaneously.

A common mistake is returning from pain and immediately doing:

longer distance + faster pace + hills + strength training + fewer rest days.

That is four new stressors at once.

Your body has no opportunity to tell you which variable it disliked.

7 things I would avoid if your back hurts after running

Avoid complete inactivity for weeks without a reason

Unless specifically advised by a clinician, prolonged inactivity is rarely the best long-term strategy for an active runner.

Avoid aggressive stretching into pain

Painful stretching is not automatically productive.

Avoid changing your entire running technique overnight

Movement changes should generally be gradual.

Avoid increasing mileage because you “feel better”

Feeling better for three days does not necessarily mean your tissues are ready for a major training jump.

Avoid blaming your shoes immediately

Look at the entire training picture first.

Avoid relying only on passive treatment

Massage or manual therapy may feel useful, but long-term recovery usually benefits from active rehabilitation and graded return to activity.

Evidence in athletes with low back pain suggests exercise approaches can improve pain and function, while evidence for individual passive or biomechanical interventions is less certain. (MDPI)

Avoid diagnosing yourself from an MRI

Imaging findings do not automatically explain pain.

A scan can show structural changes that are not necessarily the source of symptoms.

Your history and physical examination remain important.

A lesser-known fact: running may actually be protective for your back

This surprises many people.

The systematic review of low back pain among runners concluded that the relatively low prevalence and incidence observed may mean running could have a protective association against low back pain in some populations. (BMC)

That does not mean running is a treatment for every person’s back pain.

It means we should be careful about the assumption that running is inherently damaging to the spine.

The better question is:

How much running can your current body tolerate, and how can we progressively increase that capacity?

That mindset changes rehabilitation completely.

My physiotherapy takeaway

If your back hurts after running, don’t immediately conclude that your spine is damaged or that you must give up running.

Look at the bigger picture.

Your recent training load, recovery, sleep, strength, hip mobility, running volume, hills, speed and previous injuries may all influence how your body responds.

And importantly, research does not support one universal biomechanical culprit.

A 2024 review of running-injury risk factors emphasized the multifactorial nature of running injuries and cautioned against interpreting individual risk factors in isolation. (BMJ Open)

For most runners, the goal is not to create a perfectly “correct” running form.

It is to build a body capable of tolerating the running you want to do.

That means progressive loading, appropriate strength training, sensible recovery, individualized technique adjustments and early attention to persistent symptoms.

If your back consistently hurts after every run, don’t simply push through it and hope it disappears.

A physiotherapist can help determine whether the problem is coming primarily from your lumbar spine, hip, pelvis, lower limb, training load or the interaction between several factors.

And if you are experiencing neurological symptoms or any of the red flags mentioned above, get medically assessed rather than trying to self-treat.

Running should challenge your body.

It shouldn’t leave you wondering whether every kilometre is damaging your back.

Frequently Asked Questions

Can you walk with a meniscus root tear?

Yes. Walking ability does not rule out a meniscus root tear. Symptoms may mainly appear with deep knee bending, squatting, stairs or prolonged activity.

Can an MRI miss a meniscus root tear?

Yes. MRI is useful but some posterior root tears can be missed, particularly lateral root injuries. Clinical assessment remains important.

Does every meniscus root tear need surgery?

No. Treatment depends on the tear pattern, cartilage health, alignment, extrusion, symptoms, activity requirements and overall knee condition.

Can physiotherapy heal a meniscus root tear?

Physiotherapy can improve strength, movement and function, but exercise cannot anatomically reattach a completely detached meniscal root.

What does a meniscus root tear feel like?

Symptoms can include joint-line pain, pain during deep knee flexion, swelling and sometimes a popping sensation. Locking is not always present.

Can a meniscus root tear cause arthritis?

A root tear can increase abnormal joint loading and is associated with progression of cartilage degeneration, although individual outcomes vary.

How long does meniscus root repair recovery take?

Recovery generally takes several months and depends on the repair technique, healing, strength, symptoms and the surgeon’s rehabilitation restrictions.

Can you exercise with a meniscus root tear?

Some exercise may be appropriate, but painful deep flexion, pivoting and high-impact loading may need modification until the injury has been assessed.

What is meniscal extrusion?

Meniscal extrusion means the meniscus has moved outward beyond its normal position. It can occur with root pathology and may indicate impaired meniscal function.

When should I see a doctor for suspected meniscus root tear?

Seek assessment for persistent joint-line pain, recurrent swelling, a pop followed by pain, painful deep flexion, suspected extrusion or symptoms that persist despite appropriate rehabilitation.
