Pulled Hamstring
A sudden sharp or grabbing pain in the back of the thigh, often during sprinting, hills, or faster running.
Back of the thigh
Hamstring Muscle Strain
Usually not in the early stage, especially if walking or push off is painful
Usually 2 to 8 weeks, depending on the severity of the strain
Often happens suddenly during sprinting, acceleration, hills, or overstretching the hamstring
Can I Keep Running?
Running is usually not appropriate early on, especially if the hamstring is painful with walking, bending, or push off. Trying to run through a fresh hamstring strain often keeps pulling the muscle back into the same injury cycle before it has rebuilt properly.
Typical Recovery Timeline
Milder strains may improve within 2 to 4 weeks, while more significant strains often take 6 to 8 weeks or longer to rebuild fully. The hamstring often starts feeling better before it is actually ready for sprinting, hills, or harder running again.
What's Actually Going On?
A pulled hamstring happens when the hamstring muscle is overloaded beyond what it can tolerate.
In runners, this commonly happens during faster running or powerful push off, when the hamstring is working hard to control and generate force.
Sometimes it happens suddenly in one moment, while other times the hamstring has already been overloaded and fatigued before it finally reacts.
Common Symptoms
Can You Still Run With It?
Usually not at first.
If walking, bending, or pushing off is painful, the hamstring is not ready for running yet.
Once normal walking, bodyweight loading, and controlled hamstring exercises feel comfortable again, a gradual return to running can begin, usually starting with easy flat running before speed or hills.
Things That Often Need Adjusting:
Does This Sound Like You?
- You felt a sudden grab or sharp pain in the back of the thigh
- Sprinting or faster running triggered it
- The hamstring feels tight, weak, or vulnerable afterwards
- Stretching feels uncomfortable
- The leg feels less powerful or trustworthy
- The area tightens up quickly when trying to run again
Why Do Runners Get This?
This usually happens when the hamstring is asked to generate more force than it is ready for.
In many runners, the muscle was already overloaded before the strain finally happened.
Worth Getting Assessed If:
- •walking is still painful after a few days
- •the hamstring keeps tightening up again
- •you cannot run comfortably
- •strength is not returning normally
- •symptoms are not steadily improving
Get Help Sooner If You Have:
- major bruising
- significant weakness
- a popping sensation
- difficulty weight-bearing
- severe pain that worsens quickly
- Hamstrings are very easy to re aggravate if runners return to speed work too quickly.
A Note From Liesel
“A lot of runners panic when they pull a hamstring because it suddenly feels dramatic and limiting. Then, as soon as it calms down slightly, they test it too early and end up right back at the start again. Usually, the runners who recover best are the ones who respect the healing process properly and rebuild strength before chasing speed too soon.”
