Few things test a runner's patience like coming back from injury. The legs feel fine on the sofa, the itch to run is real, and the temptation is to pick up where you left off. That's also the fastest route back to the physio. Returning to running is a skill — and done well, it gets you back to consistent, pain-free miles rather than a frustrating cycle of flare-ups.
Why most running injuries are load errors
The great majority of running injuries are overuse problems — not from doing something wrong in a single stride, but from doing too much, too soon, for what your body was prepared for. The relationship between training load and injury is well described: sudden spikes in load are a key driver of injury, whereas gradually built-up load actually protects you (Gabbett, 2016). Understanding this reframes your comeback: it's about managing load, not just resting and hoping.
The principle: build capacity gradually
Your tissues — tendons, muscles, bone — adapt to the loads you give them, but they adapt slowly. Give them a gradual, progressive stimulus and they get stronger and more tolerant. Overwhelm them with a sudden jump and they break down. Every good return-to-running plan is really just a structured way of increasing load gradually enough for your body to keep up.
Before you start
A few things should be in place before your first run back: your pain should have settled enough that you can walk briskly without provoking it, and, just as importantly, the factors that caused the injury in the first place — often a strength or capacity gap — should be getting addressed. Returning to the same running on the same under-prepared body invites the same injury.
A graded return framework
A typical progression climbs in stages: pain-free brisk walking, then walk–run intervals (for example, short jogs with walking breaks), then continuous easy running, then gradually more volume, and only later added intensity such as faster running and hills. The golden rules are to increase just one variable at a time, to build volume gradually (a rough guide is no more than around 10% per week), and never to add distance and speed in the same week.
Listen to the tissue
Use a simple pain-monitoring rule: mild discomfort during a run is often acceptable, provided it settles within about 24 hours and isn't worse the next morning. Pain that climbs during the run, lingers the next day, or makes you limp is a signal to step back a level. This feedback loop, run by you, is more reliable than any fixed calendar.
Keep strengthening
Running fitness and tissue strength aren't the same thing. Continuing your strength work — particularly for the calf, hip and the area that was injured — builds the capacity that lets you absorb more running without breaking down. It's the single most under-rated part of most runners' comebacks.
Which injuries does this apply to?
These principles underpin the return from the common running injuries we treat — Achilles tendinopathy, shin splints, iliotibial band syndrome, patellofemoral (kneecap) pain and plantar fasciitis. Our individual articles on each cover the specifics, but the graded-loading backbone is the same. If you're building towards a local goal like the Ipswich Half Marathon or a return to parkrun, give yourself enough runway to progress steadily rather than cramming.
When to seek help
When to seek help. See a clinician if pain keeps returning each time you build up, if you can't progress past a certain point, or if you're not sure your injury is ready to load. Seek assessment for sharp, focal or night-time bone pain, which can indicate a stress fracture and needs a different approach.
Frequently asked questions
How soon can I run again after an injury?
It depends on the injury, but the readiness signs matter more than the calendar: settled pain, pain-free brisk walking, and progress on the underlying cause. A clinician can help you judge it.
How quickly should I increase my mileage?
Gradually — a rough guide is no more than about 10% per week, increasing just one variable (distance or intensity) at a time.
Should I run through pain?
Mild discomfort that settles within 24 hours is usually fine. Pain that worsens during the run, lingers the next day, or changes how you move means you've done too much.
How do walk–run intervals work?
You alternate short jogs with walking breaks and gradually increase the running portion as your body adapts, before moving to continuous running.
Why do I keep getting injured when I come back?
Usually because load is being increased too quickly, or the original cause (often a strength gap) hasn't been addressed. Fixing both breaks the cycle.
How BPR can help
At BPR we'll check the injured area is ready to load, address the gap that caused it, and build you a graded return-to-running plan tailored to your goal — whether that's parkrun or the Ipswich Half. You can book an assessment at bpr.rehab.
