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:
You can calculate your running pace for kilometers or miles by choosing the unit in the ‘Unit of measurement’ menu.
Running pace calculator
- Click on the value you want to calculate.
- Then enter the other two values to calculate the third.
For example, if you want to calculate your target running pace to complete 10k in an hour, you would enter:
- Distance: 10 (and choose kilometers as the unit)
- Time: 1 (in the ‘hh’ field)
👉 The calculator will generate the result (in this example ‘6’) for the pace per kilometer you should be targeting.
Example: Calculate Your Running Pace
To 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
- Choose half marathon for Distance.
When you click Calculate pace, you’ll get an estimation of your Pace per kilometer/mile: to run a sub-2 half marathon, 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 Your 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
- Enter 10 kilometers to Distance or 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 using the running pace calculator, keep in mind that running isn’t mathematics.
Elite runners may be able to maintain their pace for several hours, but 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 sports watch to get real-life running data, including pace, distance and more.
