Where running injuries tend to cluster
Most running complaints are overuse injuries concentrated in a few sites. The knee is the most common region, with patellofemoral pain (pain around the kneecap) and iliotibial band syndrome (pain on the outer knee) frequently reported. The lower leg sees medial tibial stress syndrome, often called shin splints, along with Achilles tendinopathy and calf strains. The foot contributes plantar fasciitis and, less often, stress fractures, while the hip and gluteal region account for a smaller share.
Reported prevalence varies widely between studies because of how injuries are defined and which populations are tracked, so the map is best read as relative likelihood by region rather than fixed percentages.
What usually drives them
The common thread is load that outpaces tissue tolerance: rapid increases in weekly mileage, intensity or hill work, often combined with insufficient recovery. Training error is consistently among the strongest associations across the running-injury literature, more so than any single biomechanical trait.
Persistent, sharp, or worsening pain, especially focal bone pain that hurts with hopping, deserves assessment rather than running through it. This is general educational information, not medical advice; see a qualified clinician for diagnosis and a return plan.
