Understanding treadmill speed measurements

How Fast is 12 on a Treadmill? As a runner, it is crucial to have a clear understanding of treadmill speed measurements. Whether you are a beginner or an experienced athlete, knowing how fast you are running on a treadmill can greatly impact your training and overall performance. In this section, we will delve into the importance of understanding treadmill speed and how it is measured.

When you step onto a treadmill, you are presented with various speed options ranging from 1 to 15 or even higher. These numbers can be confusing if you are not familiar with how they correlate to your running pace. Treadmill speed is measured in miles per hour (mph) or kilometers per hour (km/h). For instance, a speed setting of 6 on a treadmill would mean you are running at 6 mph or 9.7 km/h.

It is essential to grasp these measurements to accurately track your progress and set realistic goals during your workouts.

The importance of knowing treadmill speed

Understanding your treadmill speed is essential for several reasons. Firstly, it allows you to monitor your pace and make necessary adjustments to achieve your desired workout intensity. By having a clear idea of your speed, you can tailor your training to specific goals, such as building endurance or improving your sprinting abilities. Additionally, knowing your treadmill speed can help you gauge your progress over time, as you can gradually increase the speed as you become more comfortable and confident in your running abilities.

How treadmill speed is measured

Treadmill speed is measured using sophisticated sensors and algorithms that calculate the rotations per minute (RPM) of the treadmill belt. These sensors detect the movement of the belt and convert it into speed measurements. The accuracy of these measurements may vary depending on the quality and calibration of the treadmill. Therefore, it is advisable to periodically check the accuracy of your treadmill’s speed by using an external device, such as a GPS watch, to compare the readings.

Interpreting treadmill speed in relation to running pace

Understanding how treadmill speed translates to running pace is crucial for setting realistic goals and tracking your progress. The following table provides a general guideline for interpreting treadmill speed in relation to running pace:

Comparing treadmill speeds to outdoor running

It is important to recognise that treadmill speeds may not directly correlate to outdoor running speeds. Factors such as terrain, wind resistance, and temperature can significantly affect your pace when running outdoors. The cushioned surface of a treadmill also provides a slightly different running experience compared to the impact of running on pavement or trails. Therefore, it is advisable to use the treadmill speed as a reference point rather than a direct comparison to your outdoor running pace.

How fast is 12 on a treadmill?

Now, let’s address the primary question – how fast is 12 on a treadmill? A speed of 12 (mph) on a treadmill corresponds to a running pace of 5 minutes per mile or 3 minutes per kilometer. This is considered to be a relatively fast pace and is often utilized by experienced runners for interval training or high-intensity workouts. Running at this speed requires a good level of cardiovascular endurance and muscular strength.

Factors that may affect treadmill speed perception

While treadmill speed measurements are generally accurate, there are a few factors that may affect your perception of speed. One factor is the incline setting of the treadmill. Running at an incline can give the illusion of increased speed even though the belt is moving at the same speed. Additionally, the physical feedback you receive while running on a treadmill, such as the movement of the belt and the lack of wind resistance, can make the speed feel different compared to running outdoors. It is essential to take these factors into account when assessing your treadmill speed.

Tips for running at different treadmill speeds

Running at different treadmill speeds requires a strategic approach to optimize your workout and prevent injury. Here are some tips to keep in mind:

1. Warm-up and cool down:

Regardless of your speed, always start and finish your treadmill workouts with a proper warm-up and cool-down. This will prepare your muscles for the workout and help prevent post-workout soreness.

2. Gradual progression:

If you are new to running or increasing your speed, it is important to progress gradually. Start with a comfortable speed and gradually increase it over time. This will allow your body to adapt and reduce the risk of injury.

3. Interval training:

Treadmills are excellent tools for interval training. Incorporate intervals of higher speeds followed by recovery periods at a slower pace. This will improve your cardiovascular fitness and help you develop speed and endurance.

4. Proper form: Pay attention to your running form, especially at higher speeds. Maintain an upright posture, engage your core, and land with a midfoot strike. This will help you maintain efficiency and reduce the risk of injuries.

Common misconceptions about treadmill speed

There are a few common misconceptions surrounding treadmill speed that are important to address. One misconception is that running on a treadmill is easier than running outdoors. While the cushioned surface of a treadmill may reduce impact on your joints, running at higher speeds can still be physically demanding. Another misconception is that treadmill speed is directly comparable to outdoor running pace. As mentioned earlier, external factors can influence your pace when running outdoors, so it is important to use treadmill speed as a reference rather than a direct comparison.


Understanding treadmill speed is crucial for runners of all levels. By grasping how treadmill speed is measured and its correlation to running pace, you can set realistic goals, track your progress, and optimize your workouts. Remember that treadmill speed is a valuable tool, but it should be used in conjunction with other training methods to achieve your running goals. So, lace up your running shoes, step on that treadmill, and uncover the speed that will propel you to new heights in your running journey.


Is 12 kmph fast?

Whether 12 kilometers per hour (kmph) is considered “fast” depends on a few factors:


  • Running vs. walking: 12 kmph is definitely fast for walking, exceeding a brisk pace and approaching a light jog. For running, however, it falls within a range commonly used for moderate intensity workouts, depending on the individual’s fitness level.
  • Individual fitness level: For a seasoned runner, 12 kmph might be a comfortable training pace, while for a beginner, it could be quite challenging.
  • Terrain: Running uphill at 12 kmph would be more demanding than running on flat ground at the same speed.

Considering these factors:

  • For an average runner on flat ground, 12 kmph would likely be considered a moderate pace. It’s faster than a conversational pace but maintainable for longer distances.
  • For a beginner, it could be a challenging but achievable pace with proper training.
  • For an elite runner, it would be a relatively slow pace used for recovery runs or warm-up/cool-down.

Ultimately, whether 12 kmph is “fast” for you depends on your individual fitness level and training goals.

What is a jogging pace? 

A jogging pace isn’t a single, fixed speed. It varies depending on several factors, including:

Your Fitness Level:

  • Beginner: A comfortable jogging pace for a beginner might be around 4-6 miles per hour (mph) or 6.4-9.7 kilometers per hour (km/h), allowing for conversation while getting your heart rate up.
  • Intermediate: As you get fitter, your jogging pace could increase to 6-8 mph (9.7-12.9 km/h), feeling slightly more challenging but still manageable for sustained periods.
  • Advanced: Experienced runners might jog at 8-10 mph (12.9-16.1 km/h) or even faster, maintaining a conversational pace but requiring more effort.

The Terrain:

  • Flat: Running on flat terrain allows for a faster jogging pace compared to hills or uneven ground.
  • Hills: Uphills naturally slow down your pace, while downhills might allow for a faster jog but require caution for control.

Your Goals:

  • General fitness: A moderate jogging pace (6-8 mph) is suitable for improving cardiovascular health and burning calories.
  • Distance running: Slower jogs (4-6 mph) are sustainable for longer distances.
  • Speed training: You might incorporate short bursts of faster jogging (8+ mph) for interval training.
