Why Your Running Injury Keeps Coming Back
The same niggle returns every time you build your mileage. Usually the problem isn't the sore spot but a weak link further up the chain. Here is how a running assessment finds it.

The pattern most runners know too well
It goes like this. You build your mileage, the old niggle wakes up (outside-of-the-knee pain, a sore shin, a grumbly Achilles) and you back off. It settles with rest. You start again, and a few weeks later, at roughly the same mileage, it returns. The training block never quite holds together, and the injury starts to feel like something you just have to live with.
You almost never do. When an injury keeps returning at the same point in your training, it is a strong sign that the underlying cause was never addressed: only the symptom. Rest calms the irritated tissue, but the thing that overloaded it in the first place is still there, waiting for the mileage to climb back up.
Why the sore spot is rarely the cause
The place that hurts and the reason it hurts are often not the same place. Running is a chain of movements, and a weakness or restriction in one link tends to show up as pain in the next one down the road: the link that ends up absorbing the load the weak one could not.
A few common examples the clinic sees week in, week out:
- Outside-of-knee (ITB) pain frequently traces to weak hip control letting the knee drop inward on landing.
- Shin pain (shin splints) and anterior knee pain are often tied to how and where the foot strikes, and to calf and ankle load.
- Achilles and plantar-fascia problems can be driven by ankle stiffness, calf capacity, and a gait pattern that overloads the tissue with every stride. Stubborn cases sometimes respond to shockwave therapy alongside the loading work.
Treat only the sore spot and you are chasing the symptom. Find the weak link and the pain has no reason to keep coming back.
The four things a screen looks at
Before we look at your running at all, our running assessment screens the areas that account for the majority of running-injury risk. There are four that matter most:
- Single-leg control: running is a series of one-legged landings, so how well you stabilise on one leg is central.
- Hip strength: weak hips let the pelvis drop and the knee collapse inward, loading the knee and ITB.
- Ankle mobility: a stiff ankle changes how force travels up the leg and how the foot strikes.
- Lumbo-pelvic stability: a stable trunk and pelvis give the legs a solid base to push from.
This screen finds the asymmetries and weak links before we watch you run, so when we do look at gait, we already know what to look for. It is the same reasoning we apply to sports injuries generally.
What video gait analysis actually shows
Next you run on a treadmill at your normal training pace, filmed from behind, the side, and the front, with slow-motion playback we talk through together in real time. Watched frame by frame, patterns invisible at full speed become obvious: cadence, foot strike, hip drop, how the knee tracks, trunk lean, and arm swing.
The point is not to declare your form “wrong”. Very few runners need a rebuilt technique. The point is to see how your particular pattern connects to your particular injury, and which one or two adjustments will take load off the tissue that keeps flaring.
Shoes, mileage, and the load question
Two questions come up in almost every assessment. The first is footwear. We give guidance based on what we observe (your foot-strike pattern, calf and Achilles loading, and injury history) and point you to the right kind of running shop with a clear brief. We are physiotherapists, not a shoe shop, so we will not push a brand or a sale.
The second is training load. Many recurring injuries are less about how you run and more about how quickly you ramp up: jumping mileage or intensity faster than the tissue can adapt. Part of the plan is often simply a more sensible progression, so your body gets the chance to keep pace with your ambition.
Building it back so it stays fixed
The output of an assessment is deliberately small and specific: a written report within 48 hours, usually with three to six strengthening or mobility exercises chosen for your weak links, a couple of gait cues to focus on, and footwear guidance if it is relevant. A short, targeted plan you will actually stick to beats a long one you abandon.
From there it is consistency. Begin the strengthening work straight away, apply the gait cues on easy runs before harder sessions, and rebuild your load gradually. If rehab work was prescribed, a follow-up at around six weeks checks it is doing its job. That is how a recurring injury becomes a former one.
When to book an assessment
Book if the same problem keeps returning as you build mileage, if you are early in a marathon or event build and want to get ahead of trouble, or if you have a footwear decision to make. Earlier is better: issues spotted twelve weeks out can be worked on alongside training, whereas the week before a race is too late to change much.
One caveat: an assessment needs you to be able to run on a treadmill without significant pain. If you are in an acute flare, or a stress fracture is suspected, see a physiotherapist for that first: we will get you comfortable running, then look at the gait. If a diagnosis is ever in doubt, get assessed rather than guessing your way through another training block.
