Common Running Injuries and How to Get Back to Running

Most running injuries are overuse, not bad luck

It is easy to feel unlucky when a niggle turns into an injury, but most running injuries do not happen in a single moment. They build up when the load (your mileage, pace, hills or long runs) climbs faster than the tissue can adapt. Pain is the tissue telling you the demand has outrun its current capacity.

The upside of that is important: if the problem is a loading problem, then loading, managed properly, is also the solution. That is very different from something being permanently damaged, and it is why the right plan tends to work.

The usual suspects: where runners get injured

Running pain tends to cluster around a handful of familiar sites:

• Knee: patellofemoral pain (“runner’s knee”) and iliotibial band syndrome are the most common.
• Lower leg: Achilles tendinopathy and calf muscle problems.
• Shin: medial tibial stress syndrome, better known as “shin splints”.
• Heel: plantar fasciopathy, often felt as first-step pain in the morning.
• Bone stress: the one we take most seriously. It sits on a spectrum from a stress reaction to a stress fracture and needs careful, conservative loading.

Getting the diagnosis right matters, because the plan for a grumpy tendon is not the plan for a bone stress injury. That is the first job of an assessment.

Load, not rest, is usually the fix

The instinct when something hurts is to stop completely. For most running injuries that backfires: full rest only deconditions the tissue further, so you come back weaker and the same thing happens again.

The better approach is usually to reduce volume and intensity to a level the injury tolerates, then rebuild it step by step. Some running often continues, just modified. The clear exception is bone stress, which may need a genuine period of offloading. A physiotherapist can tell you exactly what to reduce, modify or pause, and just as importantly, what you can safely keep doing.

Strength is your injury insurance

Behind a lot of recurring running injuries is a capacity problem: the calf, hip and gluteal muscles are not strong enough to support the lower limb under thousands of repetitive foot strikes. Running itself does not build that strength well.

Targeted strength and conditioning raises the ceiling on what your tissues can handle, which both treats a current injury and reduces the recurrence that drives most long-running problems. It is the least glamorous part of a runner’s week and often the most protective. Running gait analysis can add value too, but we use it selectively: alongside a diagnosis, to guide changes to cadence, footwear or volume where the evidence supports them, never as a stand-alone fix.

Shin splints or a stress fracture? Knowing the red flags

Not all running pain is created equal, and a few patterns deserve caution. Shin splints and a bone stress injury both cause shin pain, but they behave differently: shin splints tend to spread along the shin and ease as you warm up, whereas a bone stress injury is usually a sharper, more focal pain that worsens with continued loading and can hurt at rest. Focal pain, night pain, or pain on hopping is a reason to pause and get assessed.

Seek urgent help (call 999) if you cannot bear weight, the joint looks deformed, or you have numbness, tingling or a cold, discoloured limb. Contact NHS 111 if pain or swelling is severe, you suspect a bone stress injury with focal pain at rest, or there is no improvement after a few days of sensible self-care.

Returning to running: earn it, don’t guess it

The most common way to re-injure yourself is to jump back to full mileage on how the leg feels on a good day. Feeling is a poor guide: pain often quietens down before the tissue has caught up.

A better approach is criteria-based: you progress when you have hit objective markers, such as symptom-free progressive loading and restored strength and running tolerance. At Kaizen we build the return around your goal (a marathon block, a return to five-a-side, or simply running pain-free) and explain each stage so you always know why you are doing it. That is what turns a recovery into a return that lasts.

When to get it assessed

Book an assessment if a running niggle is not settling, keeps returning, or is forcing you to cut runs short, and sooner rather than later if you suspect bone stress. Our sports physiotherapists see runners across five London clinics and online, from first-timers to marathoners returning to elite sport. You can self-refer and book directly; no GP letter needed.

The earlier a loading problem is diagnosed, the smaller the detour. An accurate diagnosis, a graded plan, and a return you actually earn will get you back to running, and keep you there.
