Lower back ache after running: what to know

Running repeatedly loads the hips, pelvis, and lower spine. A sudden increase in distance, hills, speed, or frequency can leave the back muscles tired and sore. Poor recovery, worn footwear, limited hip movement, or changes in running surface may also alter how force travels through the body. Pain that stays local and improves with rest is more consistent with a mechanical strain than pain that shoots below the knee, causes tingling, or is joined by weakness. Lumbar spondylosis can also contribute to activity-related back symptoms, especially when stiffness is longstanding.

Pause hard running while walking remains comfortable, then return gradually as symptoms settle. Use an easy warm-up, shorten your stride if that feels more comfortable, and avoid testing the pain with sprints or hills. Gentle mobility for the hips and back can help; stop if it produces sharp or spreading pain. Review recent training changes and allow recovery between demanding sessions. A physiotherapist can assess running form, strength, and load management if the problem keeps returning.

Book an assessment when pain lasts beyond a short recovery period, limits ordinary activity, or returns each time you run. Seek urgent care after significant trauma, or for new leg weakness, numbness around the groin, difficulty passing urine, loss of bowel control, fever, or severe pain that does not ease in a comfortable position.

Should I change my running volume or surface? Could my hip strength or stride be contributing? Do my leg symptoms suggest nerve irritation, and what rehabilitation plan is appropriate?
