Get knee pain running? It’s not ideal, we know, but everything from sharp sensations to a little discomfort while you pavement pound are nothing new – they’re something that runners have experienced for yonks.
In better news, though, there are lots that can be done about it, once you’ve determined the possible cause. Consider this your full guide to making knee pain while running a thing of the past, as well as a handy method to picking the right running shoes for you (a big step to combatting the issue).
5 possible reasons you get knee pain running
People experience knee pain running for a number of reasons, and not all of them are possible to self-diagnose. If in doubt, reach out to a physical therapy specialist, either an osteopath or physiotherapist for expert advice.
If you’re looking for a bit more information about the most common causes and if your symptoms match up with any of them, keep reading. Osteopath Nadia Alibhai breaks down the five most common causes of knee pain when running.
1. Runner’s knee (kneecap pain)
‘One of the most common causes of knee pain running is weakness in the thigh muscles (quadriceps). Your quadriceps hold the kneecap in place so that it tracks smoothly,’ says Alibhai. ‘If the quads are weak when running or if there is a muscle imbalance, the kneecap can move left to right as opposed to smoothly up and down which can cause friction and irritation.’
2. Jumper’s knee (patellar tendinitis)
‘Running can lead to repeated stress on the patellar tendon which can lead to inflammation and, thus, knee pain running. This tendon connects the kneecap to the shinbone (tibia) which is responsible for extending the lower leg.’
3. Meniscal tear
‘Runners are more likely to injure the medial meniscus (inside of the knee) rather than the lateral. Pain can be felt all over the knee with swelling over the knee, a popping sensation during the injury, knee stiffness (especially after sitting), the knee can feel locked and it can be difficult trying to bend or straighten the knee,’ explains Alibhai.
4. Iliotibial (IT) band syndrome
‘The IT band is a band of tissue that runs along the outside of the thigh, from the tensor fasciae latae where it attaches at the top of the hip, to the outside of the knee. When the tensor fasciae latae becomes tight, it shortens and puts tension on the IT band. The outside knee area can become inflamed, or the band itself may become irritated causing knee pain running. Overtraining is the most common cause as well as an inadequate warm-up or cool-down may also lead to Iliotibial band syndrome.
‘The wearing out of hyaline cartilage (lining of the joint) causes bone to grind on bone whilst running and can cause friction and pain.’
Why can running cause knee pain?
Something that might come as a surprise – it might not be the running causing your knee pain but external factors outside, like weak muscles, the surface you run on or not wearing proper running shoes (tsk tsk). Here’s how each one can cause you to come unstuck.
Muscles weakness / imbalances
‘When we run, we don’t just go forwards, we may have to nip around bends, dips in the pavements and quick stops especially in busy cities,’ explains Alibhai. ‘If the muscles around the knee aren’t strong enough to handle the quick stops and change of direction, they may not support the joint thus leading to knee pain when running. It is important to strengthen and stretch the surrounding muscles for support of the joint.’
The body is both smart and full of imbalances, that’s why the more you run the more certain dominant muscles can take over. This can lead to any number of injury issues, not just in your knees. (Remember that strength training for runners thing we mentioned, this is why it’s so important. More on how to add more into your weekly workout routine later.)
Harder surfaces (pavements and concrete, for example) absorb less impact as you run which can cause more pressure to travel back through the knee. Softer surfaces such as grass or sediment can lower the instance of knee pain from running.
Poor running form
There is a right way to run, y’know. Now, everyone’s bodies are different, we know that. But, there are a few ways to check your form isn’t exacerbating the chances of an injury.
First, though, here’s how less than brilliant form can affect your knees:
‘Running with your knees slightly tilted inwards (possible flat feet or weak gluteus medius) or with tight hip flexors (due to a pelvic tilt/leg length discrepancy) can affect the way you run,’ says Alibhai. ‘Poor form may lead to putting excess pressure at the knee joint (which can cause knee pain).’
Incorrect running shoes
‘Incorrect running shoes that have lost support and cushioning can mean more impact from the ankle, knee to the hip,’ explains Alibhai. ‘Plus, if you are a beginner, running too fast too soon can strain, muscles, joints and ligaments that aren’t strong enough to handle the workload.’ Not good.
Alibhai suggests following the 9 guidelines below to find the best shoes for you:

Is running bad for your knees?
It’s the age-old question and one people love to weigh in on with (usually) not much more expertise than their own experience. Plus, after that list of veritable knee pain causes, it can seem like running must be bad for your knee joints, right? Not if you’re strong enough. Alibhai explains:
Why strength training is so important for runners
‘Strength training provides muscle support and strength to the knee joints to protect them whilst running, as well as the surrounding muscles eg. the hips help control the knee and alignment, as well as supporting the lateral trunk movements,’ explains senior chartered physiotherapist and Pilates instructor Tracy Ward.
For those not in the know, strength training is anything that forces you to work against resistance as you exercise. And yes, bodyweight training also counts as strength training. It’s a brilliant way to build lean muscle tissue, increase muscular strength and, something that’s crucial for runners, help with endurance, too.
‘Strength training also builds muscular endurance to accommodate for long runs or frequent runs,’ explains Ward. ‘It provides an additional and different stimulus compared to running, which is only linear. Strength training allows the muscles to continually progress, adapt and grow.’
How often should runners strength train?
However, it’s not all about lower body exercises like deadlifts, squats and lunges (although these are very important). Also working on keeping your core strong is one of the most important parts of running with good form. Hoover explains:
‘Core strength is also very important to support the spine and pelvis during running and high impact activity. Running is done mostly in one plane of motion, so it develops those muscles the most, namely the quads and hamstrings. However, our bodies need to work in three planes of motion, and we need to work the muscles in all three planes to maintain balance and symmetry in the body.’
What to do if you’ve just experienced knee pain running
This is what senior chartered physiotherapist Ward says to do immediately after you’ve experienced knee pain whilst running and what to do if the pain doesn’t subside after a couple of days.
‘If knee pain occurs, take a day or two to rest with ice applied to the knee. Then, try to identify the cause – did you fall, twist it, new trainers, new route, uneven ground, longer distance, or do too many runs close together?’
‘If the pain continues or is unidentifiable, see a physiotherapist for assessment. They can diagnose the injury and provide a rehab plan, as well as advising on footwear, pacing, and scheduling of runs and strength training sessions. Kinesiology tape can also be helpful to relieve pain whilst you complete your rehab, as well as allowing you to return to running earlier.’
Stretches for knee pain
One of the most common issues is overly tight muscles pulling on the ligaments around the knee.
While there are some other conflicting opinions over the importance of stretching before or after a run, there’s plenty of anecdotal evidence to suggest it’s more than worth it.
So, we teamed up with adidas ambassador and Ldn Brunch Club run coach Charlie Brown to help demo some of the best stretches for runners with bad knees.
Try to hold each one for at least a minute. It sounds like a long time but it’s worth it if it prevents those nasty niggles.
1. Standing quad stretch
2. Hip Flexor Stretch
As well as doing this stretch, you may also benefit from bringing some lateral movements into your cross-training. Everyone loves a good side lunge!
3. Knees to chest
Your posterior chain is the series of connecting muscles, ligaments and tendons running on your back side. So, if something in the chain is tight, like your lower back (something that’s common in runners with a weaker core) – even if it’s far away from the source of pain – it can cause issues.
