What Body Type Makes the Best Runner?


Running is one of the most popular forms of exercise, and it requires strength, endurance, and a proper body structure. However, with so many different body types out there, it begs the question: what body type makes the best runner?

Body Types Explained

There are three main body types: ectomorph, endomorph, and mesomorph. Ectomorphs are thin and have a small frame, while endomorphs have a wider build and retain more fat. Mesomorphs are muscular and have a more athletic build.

Advantages of Body Types for Running

Each body type has its advantages and disadvantages when it comes to running. Ectomorphs have less weight to carry, which makes them excellent long-distance runners. Endomorphs, on the other hand, have more muscle mass, which can help propel them forward during sprints. Mesomorphs are naturally athletic and have a balance of strength and endurance, which can be useful for running various distances.

Data on Body Types Amongst Professional Runners

According to research, the majority of professional runners have a mesomorph body type. This is because they are naturally athletic and have a higher percentage of fast-twitch muscle fibers, which are responsible for explosive movements like sprinting. However, there are still successful runners with different body types, showing that body type is not the only factor at play.

The Importance of Training and Nutrition

While body type can certainly influence one’s ability to run, it is important to note that training and nutrition also play a significant role. Even an ectomorph with a naturally lean frame will not be a successful runner without proper training and fueling. Endomorphs can benefit from strength training to improve their muscle mass and power. Mesomorphs still need to train and eat a proper diet to maintain their athletic abilities.


In conclusion, there is no one “best” body type for running. Each body type has its advantages and disadvantages, and success ultimately depends on proper training and nutrition. However, mesomorphs do seem to have a slight advantage due to their natural athleticism and muscle composition. But regardless of body type, anyone can become a successful runner with dedication and hard work.
