Groin pain while running: what to know

Running repeatedly loads the adductor muscles, hip flexors, and hip joint. A sudden increase in distance, speed, hills, or training days can exceed tissue tolerance. Pain with sprinting or changing direction may involve the inner-thigh muscles. Deep pain with hip flexion, turning, or prolonged sitting can occur with hip impingement or a labral tear; stiffness and reduced range may also fit hip osteoarthritis. These conditions can present with groin pain, but the symptom does not identify one diagnosis. A history and movement examination are more useful than guessing from the location.

Pause sprints, hills, and sharp direction changes first. If ordinary walking is comfortable, use it as a lower-load option and return to running gradually only when symptoms are settling. Avoid running through a sharp pain or changing your stride to protect one side. Record the warm-up, surface, shoes, training change, and pain response afterward. Sports physiotherapy can assess strength, hip control, running mechanics, and a staged return-to-running plan.

Arrange prompt assessment if pain began with a pop, bruising, marked swelling, or inability to push off. Seek urgent help for inability to bear weight, a visibly deformed hip, severe sudden pain, fever with a hot joint, or new numbness or weakness. Book a routine assessment when pain returns each run, persists despite reducing training, wakes you, or causes limping.

Which running loads should I remove first? Does my pain pattern suggest muscle, tendon, or hip involvement? What strength or mobility findings should be checked? How should I progress back to running without provoking symptoms?
