Our pace calculator is a useful tool if you want to estimate the speed at which someone or something moves. If you want to find out how fast you are able to run or cycle, you don't need to crunch the numbers any longer - use our running pace calculator to estimate your pace in any unit of measurement you wish. You can then compare your times with the average running speed!

This article will explain:

  • The difference between pace and speed
  • How the running pace calculator works
  • What the average running speed is

The difference between pace and speed

Firstly, let's make it clear what the difference between pace and speed actually is. Although both values express similar information, they are the reverse of each other. By this we mean that by counting pace you find how much time you need to cover a particular distance, while speed is an indicator of the number of kilometers you are able to cover within one hour. As a result, we use different measurement units to express these values. Pace is given in unit of time per unit of distance, whereas speed is distance over time.

In order to count speed and pace all by yourself you need 2 formulas:

  1. Speed (km/h) = distance (km) / time (h)
  2. Pace (sec/km) = time (sec) / distance (km)

Let's take an example. If we move 50 km within 1 hour, our:

  • speed amounts to: 50km / 1h = 50 km/h
  • pace amounts to: 3600sec / 50 km = 72 sec/km

Although these two equations are not very complicated, it's easy to mix them up. That's why it's worth using the pace calculator which can save us from any mistakes.

How the running pace calculator works

The pace calculator is a tool which counts your pace and speed on the basis of the distance you've done and the time you've done it in. It is particularly useful for people who exercise regularly. You can use the running pace calculator not only when you jog but also when you cycle, skate or do any other sport which requires covering some specific distance.

All you need to do is type:

  • how many kilometers you moved
  • how many minutes it took

The calculator will automatically estimate your average speed (km/h) and pace in a variety of units. Thanks to it you don't have to convert the units in order to find out how much time you need to cover a kilometer, meter, mile or yard.

The calculator will also use this information to estimate what your race time and compare it to other runners. The race time is an adjusted estimation that takes into account that faster paces cannot be maintained for longer that slower paces. The comparisons can be done in terms of pace (in a table) or speed (as a chart) and you can even select your units (using Advanced mode).

If you only need to measure your velocity and you are not interested in your pace, you can use a more simplified calculator. The velocity calculator is a tool which needs only distance and time to estimate your speed in meters per second.

If you have your speed already calculated but you need it in another unit of measurement, you can use our speed conversion calculator. This tool enables you to convert between 5 different units of speed.

What average running speed is

If you are going to monitor your speed and pace while jogging, you should also know what average running speed is. This is important because it gives you the benchmark for you to compare your results to.

Average running speed indicates how far a person is able to run in a particular period of time. The value depends on a range of aspects such as: age, weight, height, wind and even ethnicity. However, the average human running speed is estimated to be 15 miles per hour. You can use the running pace calculator to compare your results and estimate how fit you are. It is also possible to have your score sent to you via e-mail, or share it on your preferred social media platform. Just hit the send this result button at the bottom of the calculator to keep a log of your progress as you become the fastest runner ever!

If you know that you need a harder workout but you are still not sure how much you should exercise, test yourself with our target heart rate calculator. This tool will help you set fitness goals so that you can get the best results and not overexert yourself.
