How fast are you running today? This simple running pace calculator helps you estimate the time, distance, or pace of your run. Figure out your finish time for popular race distances or how fast you need to run those miles repeats.
Running pace calculator
Enter any two variables, distance, time, or pace to calculate the third one. Choose minutes per mile, or minutes per kilometer.
- Click on the value you want to calculate.
- Then enter the other two values to calculate the third.

|Pace per kilometer Pace per mile||= :|
Example: Calculate Your Running Pace
If you want to run a half marathon under two hours:
- Enter 2 hours and 0 minutes to Time
- Choose half marathon for Distance.
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.
Example: calculate Your finish time
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
Completing a 10k 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 running watch to get real-life running data, including pace, distance, and more.
