How do I run without hurting my knees?
Almost all of it is doing too much too soon — plus cadence, shoes and the strength work that protects the joint.

Short answer
Increase your distance by about 10% a week and no more. The great majority of running knee pain is a training-load problem rather than a technique or shoe problem, and the fix is patience.
Runners' knee pain gets blamed on running itself, on shoes, and on form. The evidence points much more strongly at how quickly the load increased, which is both the most common cause and the easiest to control.
Safety
Step by step
- Increase by about 10% a week.Distance or time. This is the single most effective change. Tendons, cartilage and bone adapt more slowly than fitness improves, and the gap between them is where the pain comes from.
- Include rest days.Adaptation happens between runs. Running on consecutive days from a low base accumulates load without allowing recovery, which is the same problem by another route.
- Increase your cadence slightly.Taking shorter, quicker steps reduces the impact per stride. Aiming for around 170-180 steps a minute, or simply 5-10% quicker than your natural rate, reduces knee loading measurably.
- Land with the foot closer to under you.Overstriding — landing with the foot well ahead of your body on a straight leg — puts a braking force through the knee. Increasing cadence largely fixes this automatically.
- Strengthen the hips and glutes.Weak hip muscles let the knee collapse inward under load, which is strongly associated with knee pain. Glute bridges, side-lying leg raises and step-ups are the standard work.
- Do not chase a shoe solution.Comfort matters and there is little evidence that a specific shoe type prevents knee injury. Choose what feels good, replace them when the cushioning is flat, and do not expect shoes to fix a load problem.
- Vary the surface and the route.Always running the same camber, the same hills or the same hard surface concentrates the load identically every time. Mixing it spreads the stress.
- Stop for a few days at the first ache.Two or three days off early is almost always cheaper than the six weeks that pushing through costs. Pain that worsens during a run, or persists afterwards, is the signal.
Tips
- Walk-run intervals are a genuinely effective way to build up, not a lesser form of running. Most structured beginner programmes use them for exactly this reason.
- Track your weekly distance. Most people who develop knee pain find, on looking back, a week where it jumped considerably.
- If pain is persistent, a physiotherapist assessment is worth far more than any general guidance. They can see what you are actually doing.
Questions people ask
Why do my knees hurt when I run?
Most commonly increasing distance or frequency too quickly. Tissue adapts more slowly than fitness, and the 10% weekly rule exists to close that gap.
Will different running shoes fix knee pain?
There is little evidence that a particular shoe type prevents injury. Comfort matters, but a training-load problem is not solved by footwear.
