How to Start Running From Scratch Without Getting Injured

Every autumn we see the same pattern at the clinic: a burst of enthusiasm for running in September, followed a few weeks later by a steady stream of sore knees, tight calves and niggling shins walking through our door. The good news is that almost all of it is avoidable. Running is one of the simplest forms of exercise to start, but the body needs time to adapt to the repetitive load it places on tendons, bones and joints — and most injuries happen because that adaptation gets rushed, not because running itself is bad for you.

If you're picking up running for the first time, or coming back to it after years away, here's how to do it in a way that builds a habit rather than an injury.

Start slower than feels necessary

The single biggest cause of beginner running injuries is doing too much, too soon. Your cardiovascular fitness improves faster than your tendons, bones and connective tissue can strengthen, so it's entirely possible to feel capable of running further than your body is actually ready for. This mismatch is why so many new runners get injured in weeks three to six — right when they start feeling confident.

A run-walk approach is genuinely the best way to begin, even if it feels unnecessary. Something like one minute running, one minute walking, repeated for 20–25 minutes, three times a week, is a sensible starting point for most healthy adults. Increase total running time by no more than around 10% a week, and resist the urge to jump ahead just because a session felt easy. Consistency over months matters far more than any single fast start.

Choose surfaces and shoes sensibly

You don't need expensive running shoes, but you do need ones that are appropriate for your foot and replaced before they're worn out — a good running shop can help with this, and it's worth doing before you rack up serious mileage rather than after something starts hurting. Softer, more forgiving surfaces like park paths or a running track are kinder to your joints than pavement, particularly in the first few months. Avoid heavily cambered roads where possible, as the constant slight tilt can aggravate hips, knees and ankles over time.

If you're returning to running after a break for back, hip or knee pain, it's worth getting that assessed rather than guessing at the cause — our pain relief service is aimed at exactly this kind of persistent joint or back discomfort that flares with activity.

Build strength alongside your mileage

Running conditions your cardiovascular system quickly, but muscular strength — particularly in the glutes, calves and core — often lags behind. Weak calves are strongly linked to Achilles and shin problems; weak glutes are linked to knee and IT band pain. Two short strength sessions a week, focusing on squats, calf raises, single-leg work and some core stability, make a real difference to injury resilience and are worth building in from week one rather than after something goes wrong.

This is an area where structured guidance pays off, because the right exercises depend on your individual movement pattern and history. Our strength & conditioning programmes are built for exactly this kind of preventative work, and if you're training towards a specific event, our marathon and running preparation service takes the same principle further with a structured build-up plan.

Know the difference between soreness and injury

Some muscle soreness in the first few weeks is normal and expected. What isn't normal is pain that's sharp, localised to one spot, gets worse during a run rather than settling, or is still there the next morning affecting how you walk. Common beginner complaints include shin splints, Achilles tendon pain, and pain around the kneecap — all of which respond very well to early intervention and usually get harder to shift the longer they're ignored.

Achilles and other tendon pain in particular can become stubborn if it's left to become chronic, and for cases that don't settle with rest and loading changes, shockwave therapy is an effective option we use at the clinic to speed up tendon recovery.

Listen to your body's rhythm, not just the calendar

Give yourself rest days — running is a high-impact activity and your body needs 48 hours to properly adapt after a session, especially early on. Sleep, hydration and general fatigue all affect how well your tissues recover, so a run that feels hard on little sleep isn't a sign you're unfit, it's a sign to ease off that day. Building in a lighter "recovery week" every three to four weeks, where you deliberately reduce volume, also helps prevent the gradual accumulation of load that leads to overuse injuries.

If you do pick up a niggle that isn't settling after a few days of rest, it's far easier to resolve early than once it's become a pattern. General physiotherapy assessment can identify the underlying cause — whether that's a strength imbalance, a training error or a biomechanical factor — before it turns into something that sidelines you for weeks. If you're in south London and want an experienced eye on your running technique or a nagging issue, our team at the Vauxhall clinic is happy to help you get back out there with confidence.
