Low back pain is one of the most common complaints among runners—and for good reason. The repetitive impact of running, combined with training load, technique, and lifestyle factors, can create the perfect storm for irritation or overload in the lower back. Sometimes the cause is obvious, like a stress fracture or disc-related issue. Other times, it’s a combination of subtle movement inefficiencies and strength deficits. Whether you’re training for your next race or simply running to stay fit, understanding what’s driving your back pain is the first step to resolving it and staying injury-free.

Common Causes of Low Back Pain in Runners

While every case is individual, here are some of the most common contributors to low back pain in runners:

1. Poor running mechanics
Excessive trunk rotation, overstriding, or a stiff upper body can increase strain on the lumbar spine over time.

2. Reduced hip and trunk strength
Weak glutes, deep core muscles, and hip stabilisers can lead to compensations that overload the lower back.

3. Stiffness in the thoracic spine or hips
Limited mobility in these areas forces the lower back to move more than it should, which can irritate the lower back during repetitive motion like running.

4. Sudden increases in training volume or intensity
Going from 20km a week to 40km without giving your body time to adapt can result in overload—not just in your legs, but through your entire kinetic chain.

5. Prolonged sitting and postural habits
Many runners spend their non-training hours sitting at a desk or driving, which can lead to tight hip flexors and hamstrings—two things that don’t mix well with distance running.

Common Misconceptions About Running and Back Pain

“Running is bad for your back.”
Not true. Running, when done with good mechanics and a sensible training load, is actually beneficial for spinal health. The problem isn’t running—it’s how you run and how much you’re asking your body to handle without support.

“If your back hurts, you should stop running completely.”
In most cases, complete rest isn’t necessary. Modifying intensity or volume while addressing the underlying issues is usually more effective than stopping altogether.

“You just need to strengthen your core.”
Core strength is important—but it’s only one piece of the puzzle. Often, hip control, mobility, and running technique need just as much attention.

Effective Treatment for Low Back Pain in Runners

Treating low back pain in runners involves more than just rest and foam rolling. A tailored approach often includes:

• Identifying and addressing training errors (e.g. overuse, poor recovery)

• Improving movement patterns through video gait analysis or postural assessments

• Targeted strength work for the glutes, deep core, and hips

• Restoring mobility in the thoracic spine, hips, and ankles

• Gradual return to full training once symptoms have settled and deficits have been addressed

How to Prevent Low Back Pain as a Runner

The best treatment is prevention—and that comes down to smart training and consistent maintenance. Here are a few tips to keep your back happy on the run:

• Warm up properly with dynamic mobility drills

• Don’t ramp up distance or intensity too quickly

• Include strength training at least twice a week, especially for the posterior chain

• Stay mobile through the hips and mid-back

• Pay attention to early signs of tightness or fatigue rather than pushing through

Low back pain doesn’t have to be part of your running journey. With the right understanding of its causes, and a well-structured approach to training and movement, most runners can recover fully and return to running stronger than before.
