Every runner knows the feeling: a little ache in your shin, a tight hamstring that just won’t ease up, or a knee that complains halfway through your long run. These “niggles” might not stop you right away, but if ignored, they can turn into full-blown injuries that ruin your training.
The good news? We can reduce the risk of many running injuries, and even when they do pop up, smart management can keep you running stronger for longer.
In this blog, we’ll cover:
- The most common running injuries and their warning signs
- Why niggles happen in the first place
- Simple strategies to reduce the risk of running injuries
- What to do when pain starts creeping in
- How strength and prehab keep you consistent year-round
Now I have to make two clear points here before we dive in:
- Nothing in this blog constitutes as medical advice. I will always suggest you be assessed in person by your healthcare professional (e.g. physiotherapist).
- We can’t 100% prevent injuries, but we can reduce the risk of them occurring.
Common Running Injuries and Warning Signs
Here are some of the injuries most runners face, plus the early red flags you shouldn’t ignore.
- Shin Splints (MTSS): Pain along the inside of the shin, often from ramping up mileage too quickly.
- IT Band Syndrome: Tightness or pain on the outside of the knee, especially with running downhill.
- Plantar Fasciitis: Sharp heel pain, worst with the first steps in the morning.
- Patellofemoral Pain (Runner’s Knee): Achy pain around the kneecap during or after runs.
- Hamstring or Calf Strains: Sudden tightness or sharp twinges at the back of the leg.
Pro tip: If pain is sharp, worsening, or lingers after runs, it’s not “just a niggle.” That’s your body telling you to pay attention and it’s worthwhile getting it assessed before it becomes worse.
Why Do Niggles Happen?
Most running injuries don’t come out of nowhere, they build up over time. Common causes include:
- Training errors: Too much, too soon, too fast.
- Weakness or imbalance: Especially in the hips, glutes, and core.
- Lack of recovery: Skipping rest days, poor sleep, or under-fuelling.
- Poor mechanics or footwear: Old shoes, uneven or unfamiliar terrain, or technique issues.
Think of injuries as your body’s way of saying, “Something needs to change.”
How to “Prevent” Running Injuries
Again, we can’t 100% prevent injuries. But here’s how to reduce the risk of those niggles popping up in the first place:
- Progress gradually. You’ve likely heard of the 10% rule – don’t increase your mileage by more than 10% each week, but it’s not supported by current research. Instead, it is recommended that no single run exceed 10% of your longest run in the past 30 days.
- Strength train 2–3 times per week. Stronger muscles = less strain on your joints, ligaments, and tendons.
- Prioritize recovery. Sleep, nutrition, mobility, and true recovery runs are all important.
- Rotate shoes. Different pairs may reduce repetitive stress on the same tissues.
- Listen early. Don’t push through severe pain and hope it goes away, it rarely does.

What to Do When a Niggle Starts
If you catch it early, most niggles can be managed before they turn serious.
- Dial it back: Reduce mileage or intensity for a few days.
- Monitor pain: You may be okay to continue if it stays at or below a 2/10
- Strength + mobility: Target the weak or tight areas with specific exercises.
- Cross-train: Swap a run for cycling, swimming, or rowing to maintain fitness without impact.
- Use tools wisely: Foam rollers, massage balls, and mobility work may help, but they’re not a substitute for load management or strength work.
- Get assessed: If pain persists, get assessed by a physiotherapist before it sidelines you completely.
The Role of Prehab and Rehab
This is where most runners drop the ball. Prehab, short, targeted exercises for common weak spots, is like insurance for your body. A few minutes of hip, glute, and calf work can save you weeks off from injury.
Rehab, on the other hand, helps you bounce back when something does flare up. Having a go-to library of exercises means you’re not scrambling through YouTube or guessing what to do.
Runner’s Strength Lab includes a full library of prehab/rehab exercises to catch the niggles before they become more.
Strength Training: Your Injury-Prevention Secret Weapon
Strength training plays an integral role in building a body that can handle the demands of running.
Peak forces when we run are as follows:
- Glute Med: 4x bodyweight
- Glute Max: 1.3x bodyweight
- Quads: 1.3-2.7x bodyweight
- Hamstrings: 0.6-1.4x bodyweight
- Calves: 1.2-6.7x bodyweight
Those are pretty significant!
And they highlight not only why strength training is so important, but why we need to be lifting appropriate weight when we do. We’re looking for weight that feels like an RPE of 8 – that is, when you’ve finished your set you could still push out 2 or so more reps.
Remember, just 2–3 short sessions a week can make the difference between a season of setbacks and a season of strong, consistent running!
Key Takeaways
- Most running injuries develop gradually from training errors, weakness, or lack of recovery.
- Prevention beats rehab: strength training, prehab exercises, and smart training loads are your best defense.
- Don’t ignore early warning signs. Address niggles quickly before they become serious.
- A structured plan that combines running + strength will help to keep you consistent and injury-free.
