Avoiding Common Beginner Injuries
Most beginner running injuries share one root cause: increasing distance, frequency or intensity faster than the body can adapt. Shin splints, knee pain and Achilles irritation are the most commonly reported issues among new runners, and nearly all of them trace back to some version of doing too much too soon.
The most common beginner injuries
| Issue | Common cause | Typical early sign |
|---|---|---|
| Shin splints | Sudden increase in running volume or frequency | Dull ache along the shin during or after running |
| Runner's knee | Weak surrounding muscles, rapid mileage increase | Ache around or behind the kneecap |
| Achilles irritation | Sudden increase in speed or hill work | Stiffness or soreness at the back of the ankle |
| Plantar fasciitis | Worn shoes, sudden volume increase | Heel pain, often worst with the first steps in the morning |
None of these require alarming diagnosis to take seriously. The pattern that matters most for a beginner is simple: general well-established running advice says any pain that worsens during a run, or persists into the next day and doesn't ease with rest, deserves attention rather than being pushed through.
The single biggest fix: progress slowly
A commonly cited guideline is increasing weekly running volume by no more than about 10 percent from one week to the next. It's not an exact science, but it's a reasonable ceiling that keeps most beginners out of trouble. Combined with running 3 times a week rather than daily, as covered in how often should beginners run, this alone prevents a large share of early injuries.
Other practical steps
- Wear running shoes that fit properly and aren't worn out. Replace shoes with visibly compressed cushioning or worn tread rather than running them indefinitely.
- Warm up with a few minutes of brisk walking or easy jogging before picking up pace, rather than starting a session at full effort.
- Build general leg and core strength alongside running, even just twice a week, since weak supporting muscles are a common contributor to knee and hip issues.
- Don't run through sharp or localised pain. Dull, general fatigue is normal; a specific, worsening pain point is not.
When to take extra rest instead of pushing on
If a niggle shows up early in a run and fades within a few minutes, that's usually fine to continue with. If it persists or worsens as the run goes on, stopping and resting for a few days is a better decision than trying to run through it and risking a longer setback. This is especially relevant if you're using a walk-run approach, where it's easy to underestimate cumulative impact because the running segments feel short.
If pain doesn't improve after several days of rest, or it affects how you walk, seeing a physiotherapist or doctor is a sensible next step rather than guessing.
Browse upcoming events and build your training around a realistic date, at a pace your body can handle.
Browse eventsMy honest read, based on general patterns we hear about from runners preparing for their first event, is that injury concerns come up more often around the 3 to 5 week mark of a training block than right at the start, which lines up with when early enthusiasm tends to outpace a sensible volume increase. This is an impression, not a precise figure. If you're a few weeks into training and starting to feel invincible, that's often exactly the moment to double-check you're still progressing gradually.
Frequently asked questions
How do I know if pain is normal soreness or an injury?
General muscle fatigue that eases within a day or two is normal. Sharp, localised pain, or pain that worsens during a run or lingers beyond a couple of days, is worth taking seriously and resting from.
How much should I increase my weekly mileage as a beginner?
A commonly used guideline is no more than about 10 percent per week. It isn't an exact science, but it's a sensible ceiling to avoid overloading your body too quickly.
Do I need new shoes to avoid injury?
You need shoes that fit well and aren't worn out, not necessarily expensive ones. Replace them once cushioning feels compressed or tread is visibly worn.
Should I stretch before running to avoid injury?
A brief warm-up with easy movement or light dynamic stretching before running is generally more useful than static stretching cold muscles right before a run.
