In this article, we’ll explore the reasons why you might run slower on a treadmill and what you can do to improve your performance.

Running on a treadmill can be a convenient way to get in a workout, but it can also be frustrating when you feel like you’re not running as fast as you normally would.

Why Do I Run Slower on a Treadmill?

Running is an excellent way to get and stay fit. It’s a great cardiovascular exercise that strengthens your muscles and improves your overall health. However, if you’ve ever tried running on a treadmill, you may have noticed that you’re not able to run as fast as you would outdoors. In this article, we’ll explore why this happens and what you can do about it.

The Science Behind Running on a Treadmill

When you run outdoors, you have to overcome wind resistance and uneven terrain, which can make it challenging to maintain a consistent pace. On a treadmill, however, you’re running on a flat surface with no wind resistance, which should make it easier to run faster. So, why do so many runners find that they run slower on a treadmill?

One reason is that the belt of the treadmill is moving for you, so you don’t have to propel yourself forward like you do when you’re running outside. This may feel easier, but it actually requires less energy from your muscles, which can make it more difficult to maintain your natural running form. Additionally, the lack of wind resistance can make it harder to maintain a steady pace and feel the natural rhythm of your running.

The Impact of Running on a Treadmill

Another factor that can contribute to slower running on a treadmill is the impact on your body. When you’re running outside, the ground provides some cushioning for your feet, which helps absorb some of the impact of each stride. On a treadmill, however, the surface is harder and less forgiving, which can put more stress on your joints and lead to discomfort or injury.

Additionally, the motion of the treadmill can be slightly different from your natural running gait, which can cause muscle imbalances or strain. This can lead to slower running and make it more difficult to maintain a consistent pace.

What You Can Do About It

If you find that you run slower on a treadmill, there are several things you can do to improve your performance:

1. Warm up properly – Take the time to warm up your muscles before you start running on the treadmill. This can help you maintain your natural running form and prevent injury.

2. Focus on your form – Pay attention to your form while you’re running on the treadmill. Make sure you’re not slouching, and try to maintain a steady pace and rhythm.

3. Use incline – Increase the incline on the treadmill to simulate the resistance of running outdoors. This can help you maintain a consistent pace and improve your overall running form.

4. Mix it up – Don’t rely solely on the treadmill for your running workouts. Try to mix up your routine with outdoor runs or other forms of cardio to keep your body challenged and prevent boredom.

The Benefits of Running on a Treadmill

While running on a treadmill may not be as fast as running outdoors, there are still many benefits to incorporating it into your fitness routine. Treadmill running can:

1. Provide a consistent workout – With a treadmill, you can control the speed and incline of your workout, which can help you maintain a consistent pace and intensity.

2. Be weather-proof – Running on a treadmill is a great way to get in a workout when the weather is too hot, cold, or rainy to run outside.

3. Be low-impact – If you have joint pain or other injuries, running on a treadmill can be a lower-impact way to get your cardio in without putting too much stress on your joints.

Treadmill Running Vs Outdoor Running

Ultimately, whether you prefer treadmill running or outdoor running comes down to personal preference. While running slower on a treadmill may be frustrating, it’s important to remember that it’s still a great form of exercise. Outdoor running offers the benefits of fresh air, changing scenery, and the challenge of varied terrain. However, if you’re looking for a consistent, low-impact way to get your cardio in, treadmill running can be an excellent option.

Frequently Asked Questions

Why do I run slower on a treadmill?

Many runners have experienced running slower on a treadmill compared to outdoor running. One reason for this is the lack of air resistance while running on a treadmill. When running outside, the air resistance makes it harder to push forward, resulting in a more challenging workout. On the other hand, running on a treadmill provides a smoother surface and less air resistance, making it easier to run faster.

Another reason for running slower on a treadmill could be due to the lack of natural variations in terrain. When running outside, the terrain varies, which engages different muscles and provides a more challenging workout. However, running on a treadmill provides a consistent and flat surface, which can lead to muscle fatigue and slower running times.

How can I increase my speed on a treadmill?

To increase your speed on a treadmill, you can incorporate interval training into your workout routine. Interval training involves alternating between periods of high-intensity running and low-intensity recovery periods. This type of training can help improve your cardiovascular fitness and increase your speed.

You can also try increasing the incline on the treadmill to simulate running uphill. Running on an incline engages more muscles, making your workout more challenging and helping you build endurance and speed.

What is the best way to warm up before running on a treadmill?

It’s essential to warm up before running on a treadmill to prevent injury and improve your performance. A good warm-up routine should include dynamic stretching exercises that target the muscles you’ll be using during your workout, such as lunges, leg swings, and high knees.

You can also start your workout with a slow-paced walk or jog on the treadmill to gradually increase your heart rate and prepare your body for more intense exercise. It’s important to avoid static stretching before running as it may cause muscle strain or injury.

How can I make my treadmill workout more challenging?

If you’re looking to make your treadmill workout more challenging, there are several things you can try. Increasing the speed and incline of the treadmill can help you build endurance and improve your fitness level. You can also incorporate interval training into your routine to increase the intensity of your workout.

Another way to make your treadmill workout more challenging is to add resistance training exercises, such as lunges, squats, and push-ups, to your routine. These exercises engage different muscle groups and help you build strength and increase your overall fitness level.

How can I prevent boredom during my treadmill workout?

To prevent boredom during your treadmill workout, you can try listening to music, podcasts, or audiobooks to keep your mind engaged. You can also switch up your workout routine by incorporating different types of exercises, such as interval training or resistance training.

Another way to prevent boredom is to set goals for yourself and track your progress. Whether it’s running a certain distance or achieving a specific speed, having a goal in mind can help keep you motivated and focused during your workout.

Troubleshooting a Treadmill: Treadmill Slows Down or Treadmill Bogs Down


Running is an excellent form of exercise that can be done indoors or outdoors. Many people prefer running on a treadmill because it is convenient and can be done in any weather condition. However, some runners have noticed that they run slower on a treadmill than they do outside. There are several reasons why this may happen, and it’s important to understand them to improve your performance.

Firstly, running on a treadmill is different from running outside because there is no wind resistance. When you run outside, you are pushing against the air, which creates resistance and makes it harder to run. On a treadmill, there is no wind resistance, so it’s easier to run. This can make you feel like you are running faster than you actually are, which can be misleading.

Secondly, the surface of a treadmill is different from running on a solid ground outside. The belt of a treadmill is designed to move with your stride, which can make it easier to run. However, this can also lead to a decrease in your running speed since you are not using as much effort to propel yourself forward.

In conclusion, running slower on a treadmill is a common experience for many runners. This may be due to the lack of wind resistance and the difference in surface texture. By understanding these factors, you can make adjustments to your treadmill workouts and improve your running performance. Remember to always listen to your body and adjust your speed accordingly to avoid injury and enjoy a healthy workout.
