Is Running Fast Genetic? (Fully Explained)

Many people believe that running fast is a trait that is inherited genetically instead of being accomplished gradually with hard work and dedication.

It is very commonly believed that if a person is athletic, their children will also be eager to pursue the same passion for running. However, that may not be always the case.

In addition, researchers have done studies on this topic and discussed the dilemma of whether a person cannot improve their running speed because of genetic factors.

Key Takeaways


  • Genes that have been inherited within the family can never fade away, but genetic factors have little to no influence when it comes to the ability to run fast.
  • Building the necessary muscle strength is dependent on constant training and effort instead of relying on genetics.
  • Environmental factors can negatively affect the genes and decrease the level of certain abilities such as fast running.
  • Running fast is not genetically inherited and everyone can improve their running speed by proper training.
  • Running fast is not genetically inherited and everyone can improve their running speed by proper training.

Is running fast genetic?

Inherited genes within the family may never change, but that does not mean that genetics will determine how fast you can run. No athlete has been born with the ability to run fast, it all depends on pursuing your passion for athletics.

Genetics and Muscle Strength

Inherited genes are believed to affect the strength of muscles among humans. Variations of these genes can significantly contribute to one’s muscle strength.

Additionally, genes can also be a result of someone’s lack of strength in their muscles.  A genetic factor such as low testosterone can lead to the muscles decreasing in strength.

Although this impact may be indirect and most people may not be aware of it. This genetic factor can be a result of a certain medical condition that one inherits from family members.

However, this does not mean that muscle strength is completely connected to genetics. Even though certain genetic factors can contribute to an increase or decrease in muscle strength, anyone can improve their running speed with hard work and dedication.

There are many different fitness and health programs that can significantly help in regards to gaining strength in the muscles, regardless if you have been told that no one in your family can run fast because of genetics, and for that reason you should not waste your time on it.

Even if a person has low testosterone and weak muscles, there are programs that can be tailored to anyone’s needs in order to improve muscle strength.

Unless a person has a serious medical condition, genetics will not significantly affect their gains and strength in muscles, nor how fast they can run.

The Environment and Genetics

Some people are coerced into thinking that running fast is genetics due to environmental factors. Someone’s running speed can be influenced by the environment and the genes are also affected during this process.

Being affected by the environment in such a way can cause a person to lose their ability for fast running and the necessary strength that is needed for training.

The development of a strong athletic build and a passion for running can be compromised because of the influence of the environment such as being exposed to toxins, narcotics as well as different types of food.

These environmental factors can cause certain genes to be activated at irregular intervals and lead to the person not being able to run as fast as they can.

The performance in regards to running fast can be negatively affected by the environment and the factors that contribute to the human body not functioning in a proper way.

Is Speed Inherited Genetically?

The most well-known and most successful athletes that are praised for running extremely fast have achieved their goals with proper training such as sprinting, long distance running, and weight training.

For this reason, genetics has nothing to do when it comes to one’s running speed. Genes do not contribute to the ability to run very fast nor has anyone been born with such capabilities.

It is very unfair for people to deem fast runners as being gifted with this ability instead of expressing admiration for their hard work.

Anyone can improve their running speed, regardless of the genetic history within their family. If someone can run very fast such as their parents or relatives, it does not mean they have inherited it genetically.

Fast running heavily relies on proper training of muscles in order to reach your full potential with the inclusion of muscle coordination exercises.

Common Misconceptions

When it comes to people believing that running fast has a lot to do with genetics instead of proper training and environmental factors, there are certain additional misconceptions connected to this dilemma:

  • “Some people are born to be faster than others” – There is some truth connected to this misconception. Some people are simply born with faster-twitch muscles in their legs than other people. However, that does not mean that those muscles cannot be trained and become faster.
  • “ Running slow is genetics” – The reason why a person may be running slow has nothing to do with genetics. The most common reasons connected to slow running are lack of sufficient sleep, improper training as well as a calorie deficit.
  • “I am unable to sprint because of genetics” – Sprinting is a special ability when it comes to running and not everyone can achieve this attribute. That is why there are many programs tailored especially for people who have a passion for sprinting and genetic factors do not play a huge role in this aspect.

Final Words

Although many people may believe that genetics is somehow connected to how fast a person can run, it has been proven that genetic factors do not influence someone’s running speed.

All it takes for someone to be regarded as a fast runner is muscle training and building enough strength in order to endure the pressure of sprinting or running at full speed.

People should not identify someone’s abilities with genetics because unless you put in the necessary work and effort, genetic factors will not contribute to your success when it comes to running fast.
