Treadmill or street running? Understand the differences.






This question is very common among runners, especially if you are a beginner. Where is better? Treadmill or street running? The answer to that question, however, is very subjective. So let’s help you understand the differences between running on a treadmill or on the street.

We will analyze their differences, advantages and disadvantages and surely at the end of this article you will no longer have doubts about it. So, better to run on the treadmill or outside?

What’s the difference between running on a treadmill or running on the street?

The main difference between running on a treadmill or running on the street is that on a treadmill you don’t push the floor, after all, it’s the floor moving below you. When running outdoors, on the other hand, you push the ground to propel yourself. This difference can make running on the treadmill a little easier, especially for beginners.

Another important difference is that when running outdoors you are subject to the influence of external factors such as terrain variations, humidity and especially the influence of the wind. Therefore, this influence of external factors can generate greater difficulty, greater physical wear and tear and, therefore, greater caloric expenditure when running outdoors. However, this does not make running on the treadmill less advantageous than on the street, in fact, the two complement each other with their advantages and disadvantages that we will see below. So, here’s the tip, if you can, practice the run both ways ok?

Treadmill Running Advantages

The biggest advantage of running on a treadmill is safety, as there is no risk of injury due to uneven surfaces or adverse weather conditions. Another advantage, and this one is very important, especially for those who are starting out or who are overweight, is that the treadmill absorbs impact better, as they are softer. The difference in impact absorption can reach around 10% compared to the impact of running on asphalt.

In addition, on the treadmill you can control the pace of your run by adjusting the incline and speed. This can be advantageous in shooting training for example. Performing training on the treadmill, it is also possible to pay more attention to your running technique, as there is no influence of dangers and external distractions. Another advantage is that it doesn’t matter if it’s very sunny, cold or rainy, on the treadmill you won’t suffer from it.

Disadvantages of treadmill running

Because you move but don’t move, always running on the treadmill can become monotonous and boring. The problem with this is that people often run for less time than they would if they were running outdoors, as they lose motivation, thus hampering their evolution in the modality.

For the reason that you are indoors, even if it is air conditioned, on the treadmill dehydration can occur due to an increase in body temperature. Therefore, it is important to always pay attention to hydration and, if possible, use the treadmill close to a draft or fan.

Advantages of running in the street

The experience of running outdoors is incomparable. It provides a range of wonderful sensory stimuli, especially if you live in a coastal or mountain town with a lot of natural beauty. Many cities also have lush parks that are perfect for running, as they offer beauty and safety.

For those looking to lose weight, running outside is more advantageous. Due to air resistance, steep and uneven surfaces, caloric expenditure is greater. If you are training for a road race, of course you can train on the treadmill too. However, nothing better than running as close as possible to simulating the conditions you will find in the race. Therefore, it is a great advantage to carry out your training on the street.

Disadvantages of street running

Among the disadvantages of running outdoors, one of the main highlights is the greater impact and risks of variations in terrain. This increases the risk of injury and accidents. On very sunny days, very low temperature or heavy rain, it is also riskier to go out for a run outside. Depending on the training location, if it is a street or avenue for example, the risk of accidents due to the flow of vehicles is also considerable. Therefore, try to run in specific places to practice the sport, thus minimizing these risks.

Another disadvantage of running outdoors is the lack of time for some people for example. Depending on where you live, it’s easier to go to a gym close to home to run on the treadmill, than having to move to a specific and safe place to run outdoors.

Which is more slimming, running on the treadmill or running outside?

This question is very common, however, it was already answered above when we mentioned that due to some factors, the energy expenditure running outside is higher. But don’t worry, this difference is not that big and if you want to lose weight and can only run on the treadmill, this won’t be a problem. To compensate for this, if possible, just run or even walk a little longer on the treadmill and this will be compensated.


In summary, running outdoors and on a treadmill each have their own pros and cons. While running outdoors can be more challenging and motivating, it can also be less safe and uncomfortable. Running on a treadmill is safer and more convenient, but it can also be less challenging and more tedious. Choosing between running outdoors or running on a treadmill depends on your personal preferences and training goals. Our recommendation is that if possible, use both variations in your training. Also, always remember the importance of being supported by an area professional.
