Running is one of the most accessible sports. But there are many myths around it: “running destroys knees”, “without strength training you will definitely get injured”, “there is a perfect technique”, “you cannot increase mileage by more than 10%”, etc.

If we look at scientific research and meta-analyses, the picture becomes much more interesting and not so obvious.

Let’s look at what science actually knows about running, injuries, and health.

1. Running and Health: Does Running Reduce Mortality Risk?

Yes. And this is one of the strongest conclusions from research.

A systematic review and meta-analysis (232,149 people) showed that running is associated with:

  • −27% risk of death from all causes
  • −30% risk of death from cardiovascular disease
  • −23% risk of death from cancer

Moreover, even a small amount of running has an effect — you don’t have to run a lot. (PubMed)

Other long-term studies also showed that runners live about 3 years longer than non-runners. (PMC)

Important conclusion

From a medical perspective, it is better to run a little than not run at all, and increasing volume does not necessarily increase benefits.

This is very important for amateur runners: health ≠ maximum mileage.

2. How Often Runners Get Injured

Running injuries are indeed common.

According to systematic reviews:

  • injuries occur in about 40–45% of runners

  • injury incidence — 2.5–33 injuries per 1000 hours of running

  • most commonly injured:

    • knee
    • lower leg
    • Achilles tendon
    • foot (PMC)

A meta-analysis showed:

  • beginners get 17.8 injuries per 1000 hours
  • experienced runners — 7.7 injuries per 1000 hours (PubMed)

Very important conclusion

The most dangerous group is beginners. Most injuries occur in the first year of running.

3. What Causes Injuries (Most Important Section)

The most modern research — umbrella systematic review 2024 — showed that injuries are caused not by a single factor, but by a combination of factors:

Main risk factors:

  • training volume
  • sudden changes in load
  • runner experience
  • anatomy and biomechanics
  • lifestyle and recovery
  • previous injuries (PMC)

Key discovery of recent years

Injuries more often occur not because of gradual volume increase, but because of a single training session that is too long or a sudden spike in load.

This challenges the classic “10% rule”.

4. Running Technique and Injuries — The Unexpected Truth

Many people think:

  • you should run on the forefoot
  • you need perfect technique
  • you need to change cadence
  • you need to correct foot strike

But a systematic review and meta-analysis showed:

The relationship between running biomechanics and injuries is weak. Evidence that technique directly causes injuries is limited. (ScienceDirect)

In simple terms

There is no single “correct running technique” that protects from injuries.

The body adapts to the technique you run with.

Injuries are more related to load, not technique.

5. Do Strength Trainings Prevent Injuries?

This is a complex question.

Research shows:

  • strength training may reduce injury risk

  • but the evidence is moderate, not absolute

  • more effective are:

    • neuromuscular exercises
    • stabilization
    • gait retraining
    • comprehensive programs (PMC)

Also, a review on injury prevention showed that:

Despite many injury prevention programs, the injury rate among runners has not decreased much over the past decades. (PubMed)

Very important conclusion

Strength training is useful, but it is not a magical protection against injuries.

6. Most Common Running Injuries

According to systematic reviews:

Top injuries:

  1. Achilles tendinopathy
  2. Shin splints (medial tibial stress syndrome)
  3. Patellofemoral pain syndrome (runner’s knee)
  4. Plantar fasciitis
  5. IT band syndrome
  6. Ankle sprains (PMC)

In other words: 80% of injuries are overuse injuries, not acute injuries.

7. The Main Injury Factor — Not What People Think

If we summarize all modern research, we get:

The main cause of injuries is load, not:

  • technique
  • shoes
  • surface
  • stretching
  • strength training

Injuries occur when load exceeds the tissue’s ability to adapt.

This is the key model of modern sports medicine:

Load vs Capacity Model

If:

load > tissue adaptation → injury

8. Practical Recommendations (Most Important Section)

Here is what actually follows from scientific research.

1. The most dangerous moment — sudden increase of the long run

You should increase the length of the long run very slowly.

This is more important than weekly volume.

2. Beginners get injured more often

Therefore beginners should:

  • run slowly
  • run little
  • increase very gradually
  • take rest days

3. Any running is better than no running

Even:

  • 1–2 runs per week
  • 10 minutes of running
  • slow running

already reduces risk of death and cardiovascular disease.

4. There is no perfect running technique

You should not:

  • force switching to forefoot running
  • change cadence
  • “relearn how to run”

It makes sense to change technique only in case of injuries.

5. Strength training is useful, but not a panacea

Strength training:

  • improves running economy
  • improves stability
  • may reduce injuries
  • but does not guarantee no injuries

6. The Safest Training Strategy

If we simplify scientific recommendations:

The safest model:

  • slow running
  • gradual increase
  • stable weekly volume
  • rare load spikes
  • enough sleep
  • proper nutrition
  • rest

9. The Most Important Idea of the Whole Article

If we summarize ALL research:

Running does not cause injuries.

Injuries are caused by increasing load too quickly.

This is the main conclusion of modern sports medicine.

10. One More Important Conclusion

From a health perspective:

The best runner is not the fastest one. The best runner is the one who runs for 10 years without injuries.
