5 key factors that influence running injuries

TL;DR

Running injury prevention isn’t about one magic fix. It’s about getting the basics right, consistently. Here are the top five factors that influence injury risk, based on both research and what we see every day in the clinic.

Running Injury Prevention: 5 Key Factors That Make the Difference

Injury is the word every runner dreads. One minute you’re building fitness and chasing goals, the next you’re swapping your trainers for an ice pack. Over the years, both in my coaching and alongside physios at the clinic, I’ve seen the same patterns appear again and again.

It’s not usually “bad luck.” It’s a mix of training decisions, recovery habits, and lifestyle factors that tip the balance from healthy to hurt. Here’s what the evidence says, and what I’ve seen firsthand, about how to keep yourself on the road and out of the physio’s waiting room.

1. Training load and training errors

Whether you’re brand new to running or have been at it for years, sudden changes in training load are one of the biggest culprits for injury. That could mean:

• Volume: Jumping your weekly mileage up too quickly.
• Speed: Going from easy miles to a block of intense speedwork overnight.
• Terrain: Swapping flat routes for steep hills or technical trails without giving your body time to adapt.

All of these variables are important for building fitness, but change too many at once and you overload tissues that aren’t ready yet. Think of it like building a house: you need to strengthen the foundations before adding another floor.

2. Rest and recovery

Life doesn’t pause for your training plan: work, family, and social commitments can easily eat into the time your body needs to rest. But recovery is when the magic happens:

• Sleep is when your body repairs and adapts.
• Rest between sessions allows muscles to recover from both running stress and the other demands you put on them.
• Nutrition fuels the repair process. Skimping here can slow recovery and increase injury risk.

Sometimes, just adding an extra rest day after a particularly hard or long run is enough to keep you healthy in the long term.

3. Strength training

The evidence is strong on this one: runners who strength train are less likely to get injured. Lifting weights (or using bodyweight exercises) builds tissue tolerance and resilience, and can even make you a more efficient runner.

In the clinic, we’ve seen huge differences when runners swap endless “junk miles” for a couple of focused strength sessions each week. Adding load gradually (whether with dumbbells, kettlebells, or resistance bands) helps prepare your muscles, tendons, and bones for the repetitive impact of running.

4. Training age

Your “training age” is essentially your running CV: how much experience you have not just in running, but in other sports that demand running, jumping, and change of direction.

A footballer-turned-runner might adapt quickly to mileage increases because their body’s already used to high-impact movement. Someone brand new to running will need to progress more cautiously. Knowing your own background can help you set realistic paces for progression.

5. Footwear

There’s a lot of marketing noise around running shoes, but the evidence linking specific models to injury prevention is… thin. No single brand or style will magically stop injuries.

Where footwear does make a difference is when you make a drastic change. For example, moving from a highly cushioned shoe to a minimal drop racing flat overnight. That sudden shift changes how forces are distributed through your body, and tissues may not be ready for it.

The best advice? Go with the “comfort filter.” If the shoe feels good on your foot and works for your stride, that’s usually the right choice for you.

The bottom line on running injury prevention

There’s no way to make yourself 100% injury-proof but you can stack the odds in your favour. Get the basics right: progress training gradually, recover well, build strength, know your starting point, and choose footwear that works for you.

Running injury prevention isn’t about being cautious to the point of never pushing yourself. It’s about being smart enough to know when your body’s ready for the next step. Listen to it, respect it, and you’ll spend more time running and less time rehabbing.
