Quad Pain in Runners

Quad pain in runners is usually load-related — eccentric damage from downhills or a sudden volume spike. True strains are less common.

Common causes

  • Eccentric overload (downhills)
  • Quad strain
  • DOMS from new stimulus
  • Patellar tendon referral

Red flags — stop and see a pro

  • Sudden sharp pain mid-run
  • Bruising
  • Inability to extend the knee
