Running is one of the most accessible and rewarding ways to stay fit—but it’s also one of the most common sources of injury I see in the clinic. Whether you’re training for your first 5K or logging serious weekly mileage, injuries usually aren’t “bad luck.” They’re predictable, and more importantly, preventable.
Let’s break down the most common running injuries, why they happen, the early warning signs to watch for, and how to stay ahead of them.
The Real Reason Runners Get Injured
Before diving into specific injuries, it’s important to understand the big picture.
Most running injuries come down to three key factors:
- Load management: Doing too much, too soon (volume, intensity, or frequency)
- Strength deficits: Weak muscles can’t absorb load effectively
- Biomechanics: The way your body moves—often influenced by mobility, control, and fatigue
When these factors aren’t balanced, tissues become overloaded. That’s when pain starts.
Most Common Running Injuries
1. Plantar Fasciitis
What it is
Pain under the heel or arch, caused by irritation of the plantar fascia (a thick band of tissue under your foot).
Why it happens
- Sudden increase in running volume
- Poor foot strength or calf tightness
- Inadequate recovery
Early warning signs
- Sharp pain with your first steps in the morning
- Pain at the start of a run that eases, then returns after
Prevention strategies
- Gradually increase mileage (no more than ~10% per week)
- Strengthen your feet (e.g. towel scrunches, calf raises)
- Don’t ignore early stiffness—address it quickly
2. Achilles Tendinopathy
What it is
Pain and stiffness in the Achilles tendon, usually just above the heel.
Why it happens
- Overloading the tendon (especially hills or speed work)
- Weak calves
- Sudden changes in training intensity
Early warning signs
- Morning stiffness in the tendon
- Pain that “warms up” during a run but worsens later
Prevention strategies
- Build calf strength (heavy, slow calf raises are key)
- Introduce hills and speed gradually
- Allow recovery days between hard sessions
3. Iliotibial Band Syndrome (ITB Syndrome)
What it is
Pain on the outside of the knee caused by irritation of the IT band.
Why it happens
- Weak hip stabilisers (especially glutes)
- Poor control during running
- Sudden increases in downhill running or mileage
Early warning signs
- Sharp or burning pain on the outer knee
- Pain that worsens the longer you run
Prevention strategies
- Strengthen glutes (e.g. side-lying leg lifts, hip thrusts)
- Avoid sudden spikes in distance
- Monitor running form, especially when fatigued
4. Patellofemoral Pain Syndrome (“Runner’s Knee”)
What it is
Pain around or behind the kneecap, especially during loading activities.
Why it happens
- Poor knee tracking due to weak hips/quads
- Overuse without adequate strength
- Biomechanical inefficiencies
Early warning signs
- Pain when running, squatting, or going downstairs
- Ache around the kneecap after sitting for long periods
Prevention strategies
- Strengthen quads and hips
- Avoid sudden increases in intensity (e.g. speed work)
- Check running cadence and form
5. Shin Splints (Medial Tibial Stress Syndrome)
What it is
Pain along the inner edge of the shinbone.
Why it happens
- Rapid increase in running volume
- Poor load tolerance in lower leg muscles
- Hard running surfaces or worn-out shoes
Early warning signs
- Diffuse aching along the shin
- Pain that starts during or after running
Prevention strategies
- Progress training gradually
- Strengthen calves and lower leg muscles
- Rotate running surfaces and footwear
The Golden Rules of Injury Prevention
If you take nothing else away from this, focus on these:
1. Respect Load
Your body adapts to what you consistently do—not what you suddenly throw at it.
2. Strength Train (Yes, Even Runners)
2–3 sessions per week focusing on:
- Calves
- Glutes
- Quads
- Core
3. Listen to Early Warning Signs
Pain that:
- Persists for more than a few days
- Changes how you run
- Gets worse over time
…is your cue to act, not push through.
4. Consistency Beats Intensity
A steady, progressive plan will always outperform sporadic bursts of motivation.
When to Seek Help
If pain is sticking around despite rest or modifying your training, it’s worth getting assessed. Early intervention can mean the difference between a minor setback and weeks (or months) off running.
Running Assessments and Physiotherapy at SPHC
Running injuries aren’t inevitable. With the right balance of training, strength, and awareness, you can stay consistent—and that’s where the real progress happens.
If you’re dealing with persistent pain or want a tailored plan to stay injury-free, a physiotherapist can help you address the root cause—not just the symptoms.
