Running pace calculator

The running pace calculator helps you to calculate the time, distance or pace of your run. Calculating your pace is not only interesting, but also useful, as it helps you to run and train better.

Want to know what your pace was on your 10K, 50-minute run? Or calculate what your running pace has to be for a sub 2:00 half marathon? Find out with our running pace calculator.

Enter any two values to calculate the third:

  • time
  • distance or
  • pace

You can calculate your running pace for kilometers or miles by choosing the unit in the ‘Unit of measurement’ menu.

Example: calculate YOUR RUNNING pace

Calculate your running pace. Divide the distance you ran with your running time.

If you want to run a half marathon under two hours, enter 2 hours and 0 minutes to Time and and choose half marathon for Distance. When you click Calculate pace, you’ll get your Pace per kilometer/mile. So, to run a half marathon under two hours, you’d need to run faster than 5:41 per kilometer, or 9:09 per mile.

Enter any two values to calculate the third: time, distance or pace.

Example: calculate RUNNING finish time

Calculate your running time. Multiply your running pace with the distance you ran.

Let’s say you know you can run comfortably at 7 minutes per kilometer and you want to know how long a 10K run would take at that pace. Enter 7 minutes per kilometer to Pace and enter 10 kilometers to Distance. You can also choose 10K from the ‘Select an event’ drop-down menu.

When you click Calculate time, the calculator will show you your finish time. Ten kilometers at a 7 min/km pace would take you 1 hour and 10 minutes.

Real life vs. the running pace calculator

When you use the running pace calculator, keep in mind that running is not mathematics.

Elite runners may be able to maintain their pace for several hours. If you’re a less experienced runner, running at a pre-specified pace will get harder as you get tired.

So, a word of caution: don’t estimate your marathon time based on your 100m personal best. Or your 10K finish time based on your 5K pace, for that matter.

And you don’t have to settle for estimations: Track your runs with a premium sports watch to get real-life running data, including pace, distance and more.
