How to calculate running pace

Enter any two of distance, time, and pace to calculate the third — useful for planning a run or checking a race result.

How pace is shown

Pace is entered and displayed as minutes:seconds per kilometer, the most common way runners talk about pace.

Common uses

  • Plan a target finish time for a race distance.
  • Check your average pace from a run's total distance and time.
  • See how long a given distance takes at a target pace.

Worked example

Running 10 km in 50 minutes works out to a 5:00 min/km pace and a 12 km/h speed.

Preguntas frecuentes

What time format should I use?

Use H:MM:SS for times over an hour, or MM:SS otherwise — for example 1:05:00 or 25:30.

Does it support miles?

Distance and pace are calculated in kilometers. Convert your distance to kilometers first if you're working in miles.

Which mode should I use to plan a race?

Use "distance + pace → time" with your goal pace to see the finish time it would produce for that race distance.
