July 5, 2016

Want to know what your pace was on your 10K, 50-minute run? Or calculate what your 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

Choose kilometers or miles from the ‘Unit of measurement’ menu.

Example: How to calculate pace

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 press 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: How to calculate finish time

Let’s say you know you can run comfortably at 7 min per kilometer and you want to know how long a 10K run would take at that pace. Enter 7 min 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 press Calculate time, you’ll get your finish time. Ten kilometers at a 7 min/km pace would take you 1 hours 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.

Estimating your finish time in real time

If you don’t want to carry your laptop or smartphone on your 10K run to estimate your finish time using our running pace calculator, you can use a running watch that does that for you.

The Polar M430 GPS running watch calculates your estimated finish time in real time.

The Polar M430 GPS running watch calculates your estimated finish time in real time. Set your target distance and the watch will estimate how long it’ll take you to finish at the pace you’re running at. If you slow down or speed up, the estimation will change accordingly.

It’s like magic. Or science.

Or both.
