How it is calculated
Pace = time ÷ distance; time = pace × distance; distance = time ÷ pace.

- 6.21
How it is calculated
- Pace = time ÷ distance; time = pace × distance; distance = time ÷ pace.
- 1 mile = 1.609344 km: pace per mile = pace per km × 1.609344.
- Speed (km/h) = 3,600 ÷ pace in seconds per km. Durations shown are rounded to the second.
Example
10 km in 50 min: pace 5 min per km, or 8 min 3 s per mile; speed 12 km/h (7.46 mph).
Good to know
- Average pace over the whole course: climbs, wind and stops are not taken into account.
- Does not predict a time over another distance.
Sources
- International yard and pound agreement, 1959: 1 international mile = 1,609.344 m
When to use it
- Find your pace per kilometre or mile from a run’s time and distance.
- Compare pace units and average speed without projecting a future performance.
Frequently asked questions
How do I calculate running pace?
Divide total time by distance. For example, 50 min ÷ 10 km = 5 min per km.
What is the difference between min/km and min/mile?
They use different distance units. An international mile is 1.609344 km, so the time per mile is longer.
Does this predict my time over another distance?
No. It calculates the relationship between the values you enter but does not predict performance over a different distance.
