Tight hamstrings after a run usually ease with an easy cool-down, gentle stretching or mobility work, and good recovery. If the tightness keeps coming back, it often points to strength, load or mechanics that a physiotherapist can assess.

Why hamstrings feel tight after running

  • A sudden jump in mileage, speed work or hills
  • Weak hamstrings or glutes doing more work than they can handle
  • Long hours of sitting before or after runs
  • Low back or nerve irritation that feels like tightness

What often helps

  • A 5 to 10 minute easy jog or walk to cool down
  • Gentle hamstring stretches or leg swings, without forcing it
  • Strength work such as bridges, Romanian deadlifts and hamstring curls
  • Sleep, hydration and spreading out hard sessions

When to get it checked

See a physiotherapist if you felt a sudden pull or pop, see bruising, or the tightness lasts more than a couple of weeks or limits your running.

At Performance Sports Therapy in Gloucester, our physiotherapy team can help you find the cause and build a plan.
