Low back pain from running: what causes it, how to treat it, and how to prevent it

June 11, 2022

Low back pain from running is common, but it is not something you should just push through. In many runners, the problem is less about a single “injury” and more about how your back, hips, core, and legs are handling repeated impact.

The good news is that many cases improve when you adjust training load, reduce irritation, and rebuild support through better movement, strength, and recovery habits.

Why running can trigger low back pain

Running is a repetitive activity. Each step asks your body to absorb force, stay balanced, and transfer load from the legs through the hips and trunk. If one part of that chain is overworked or not supporting well, the lower back can take on extra stress.

Common contributors include:

Increasing mileage, speed work, or hills too quickly
Weak or delayed core engagement
Stiff hips or tight muscles that limit stride mechanics
Uneven loading side to side
Worn-out or poorly fitting running shoes
Recovery issues such as poor sleep or high training fatigue

What low back pain from running often feels like

Runners often describe a dull ache, stiffness, or a sharp twinge in the lower back that appears during or after a run. It may be worse on hills, after longer efforts, or when fatigue sets in.

It may also show up as:

Pain near one side of the lower back or just above the hips
Discomfort that eases with rest but returns when running resumes
Stiffness when bending, getting out of a chair, or tying shoes
A feeling that your trunk is not staying “stable” once you get tired

If pain travels below the knee, includes numbness, tingling, weakness, or follows a fall or sudden injury, get assessed by a qualified health professional before returning to running.

What to do first if your back hurts while running

Start by reducing what is aggravating it. That often means cutting back on speed, hills, and long runs for a short period, then gradually rebuilding as symptoms settle.

Helpful first steps usually include:

Shorten or slow runs that make pain worse
Avoid steep hills temporarily, especially downhill running
Check whether your shoes are worn out or not suited to your current mileage
Use light mobility work for hips and trunk if it feels relieving
Prioritize sleep and recovery between sessions

If you are also dealing with tightness or fatigue around the trunk, a support belt may be useful as a short-term comfort aid while you address the underlying issue.

A simple support option for runners who want extra abdominal and lower-back stability during activity.

Why it may help: It can be a practical short-term layer of support while you reduce irritation and rebuild strength.

How to reduce the chance it comes back

The best long-term fix is usually not one single stretch or one special exercise. It is a combination of better load management, trunk strength, and running mechanics that let your body handle impact more evenly.

1. Build core endurance, not just core effort

A strong core does not mean bracing hard all day. It means your trunk can stay controlled when fatigue builds. Planks, side planks, dead bugs, bird dogs, and similar exercises are useful when done consistently.

2. Respect training progression

One of the most common mistakes is changing too many variables at once. If your back starts hurting after a jump in mileage, speed, or hill work, that increase may be the trigger.

3. Check your shoes and surfaces

Running shoes that are past their best, too soft, too firm, or a poor fit can alter how your body absorbs impact. If possible, mix in softer surfaces and replace shoes before they are heavily worn.

4. Don’t ignore hip and leg issues

Pain in the feet, knees, or hips can change how you run and shift load into the lower back. If an old injury still changes your stride, that is worth addressing.

5. Use hills carefully

Hills increase demand on the trunk and hips. If downhill running makes your symptoms worse, ease back on steep descents and focus on controlled posture.

Should you keep running with low back pain?

Sometimes yes, but only if the pain is mild, does not worsen during the run, and settles quickly afterward. If pain increases as you run, changes your form, or lingers afterward, it is smarter to reduce load and reassess.

The goal is not to force training through pain. The goal is to find the smallest change that lets symptoms calm down while preserving as much fitness as possible.

When to get help

See a physiotherapist, sports medicine clinician, or other qualified professional if:

Pain keeps returning every time you run
You have pain that radiates, tingles, or causes numbness
You cannot run or walk normally
The pain followed a fall, twist, or sudden event
Symptoms are not improving after a few weeks of sensible load reduction

A professional can help identify whether the main issue is mobility, strength, load tolerance, or something that needs a more specific plan.

FAQ

Why does my lower back hurt only when I run?

Running adds repeated impact and trunk demand. If your core, hips, shoes, or training load are not supporting that demand well, the lower back may be the first place you notice it.

Is low back pain from running always serious?

No. Many cases are related to overload, stiffness, or poor support and improve with better load management. But persistent, worsening, or radiating pain should be checked by a professional.

Do I need to stop running completely?

Not always. Some runners can keep moving with reduced volume or intensity while symptoms settle. If running clearly makes the pain worse, take a step back first.

Can a support belt help?

A support belt may help some runners feel more stable or comfortable during activity, but it is not a substitute for addressing the cause of the pain.
