How to lower your risk of running injuries

Running is good for you — and hard on you

Running is one of the simplest ways to stay active. You need a pair of shoes and a door, and in Canada you can do it almost anywhere, from a city path to a gravel road. It is good for your heart, your mood and your sleep.

It also asks a lot of your legs. Each stride sends force through your feet, shins, knees and hips, and you take thousands of strides in a single run. That is why running injuries are common. Sore knees, aching shins, a grumpy Achilles tendon and painful heels are the kind of overuse problems runners know well.

Here is the honest part. No plan can promise you will never get hurt. But the research does point to a handful of habits that lower your odds. This guide walks through what has good evidence behind it, and where popular advice is weaker than people think. The goal is risk reduction, not a guarantee.

Build up slowly — the idea with the best support

If you take one thing from this guide, make it this: change your training a little at a time.

Most running injuries are overuse injuries. They happen when you ask your body to do more than it has had time to get used to. The tissue that takes the load — tendon, bone, muscle — needs weeks to adapt, and it adapts slower than your fitness and enthusiasm grow.

A systematic review looking at whether training changes are linked to running injuries found the evidence is limited overall, but what does exist points the same way: big, sudden jumps in how far you run raise the risk. Three of the studies it reviewed found more injuries when runners increased their weekly distance by more than about 30% [1]. So the takeaway is not a magic number to hit, but a clear direction — avoid sharp spikes.

In plain terms:

• Add distance gradually from week to week, not all at once.
• After an easy week, a break, an illness or an injury, step back down and rebuild rather than jumping straight to where you left off.
• Treat a new race goal, hill sessions or speed work as extra load too, not just total kilometres.
• If something starts to ache, that is a signal to hold steady, not to push harder.

You may have heard of the "10% rule" — never add more than 10% to your weekly distance. It is a reasonable, cautious habit, but be aware it has never been proven in a strong trial. Use it as a rough guide, not a law.

Strength training — worth your time

Outside of running itself, strength training has some of the best evidence for preventing sports injuries.

A large review of randomised trials across many sports found that strength-training programs cut injuries markedly, and worked better than stretching or balance drills [2]. A later analysis by the same group reported that strength training reduced both sudden and overuse injuries, and that more strength work tended to bring more protection [3].

A fair caveat: when researchers looked only at studies of endurance runners, exercise programs did not clearly lower injury risk overall — but programs that were supervised did show a benefit, probably because people actually stuck with them [4]. In other words, strength work helps most when you do it properly and keep it up.

You do not need a gym membership or heavy barbells to start. Two short sessions a week focused on your hips, glutes, calves and legs is a sensible, well-supported place to begin.

Sleep and recovery — the quiet ingredient

Your body does its repair work while you rest, not while you run. Rest days and sleep are when tissue rebuilds and adapts.

Sleep matters more than many runners realise. In a study of young athletes, those who regularly slept fewer than eight hours a night were about 1.7 times more likely to get injured than those who slept more [8]. Sleep is not the only factor, but it is one you can influence. Aim for consistent, decent sleep, and build genuine easy days and rest days into your week rather than running hard every time.

Shoes — be honest about what they can and cannot do

Running shoes are where a lot of money and marketing meet, so it is worth being clear-eyed.

The best evidence is mixed. A Cochrane review — a careful summary of the trials — found that different shoe types, including cushioned versus minimalist, made little clear difference to how many runners got hurt, and the certainty of that evidence was low [5]. So there is no single "injury-proof" shoe.

That said, one large trial found the answer may depend on the runner. Heavier runners had a lower injury risk in more cushioned shoes, while cushioning mattered less for lighter runners [6]. The practical advice is simple: pick shoes that feel comfortable and suit your body, replace them when they are worn out, and if you switch to a very different style — such as minimalist shoes — change over slowly to give your feet and calves time to adjust.

Warm-ups and stretching — helpful, but not a shield

A gentle warm-up before you run — a few minutes of easy walking or jogging to raise your heart rate and loosen up — is a reasonable habit and can make the first kilometre feel better.

But do not expect stretching to protect you from injury. A review of the research found that routine static stretching (the hold-and-count kind) as part of a warm-up did not reduce injury rates [7]. It is fine if you enjoy it, but it is not the safeguard it is often sold as. Your gradual build-up and strength work are doing far more.

Listen to the early niggles

Injuries rarely arrive out of nowhere. Usually there is a warning: a small ache that shows up mid-run, a tender spot the morning after, a niggle that creeps a little further each week.

The runners who stay healthy tend to be the ones who respond early — easing off, swapping a run for a rest day or a gentler activity, and letting a small problem settle before it becomes a big one. Pushing through pain in the hope it will "loosen up" is how minor niggles turn into weeks on the sidelines.

When to see a professional

Most running aches settle with a few sensible easy days. But it is worth getting checked by a regulated health professional, such as a physiotherapist, if:

• Pain is getting worse rather than better, or it is not improving after one to two weeks of easing off.
• Pain changes how you walk or run, or you feel it during everyday activities, not just running.
• You have sharp, pinpoint bone pain, or pain that wakes you at night.
• You keep getting hurt in the same spot, or you are not sure how to train around a recurring problem.

Across most of Canada you can see a physiotherapist directly, without a doctor's referral, though it is worth checking your own coverage. A physiotherapist can assess what is going on, help you recover, and build a strength and training plan suited to you — which is exactly the kind of individual guidance a general guide like this cannot give.

Run because you enjoy it. Build up slowly, add some strength work, sleep well, and treat the early warning signs with respect — and you tilt the odds in your favour.
