How is pace calculated?

Total time in seconds is divided by the distance to get seconds per kilometre, then shown as minutes and seconds. The per-mile pace multiplies by 1.609344.

Can I enter miles instead of kilometres?

The distance field is in kilometres. Convert miles to kilometres first (1 mile = 1.609 km); the per-mile pace is still shown in the result.

What's the difference between pace and speed?

Pace is time per distance (minutes per km); speed is distance per time (km/h). They describe the same run from opposite directions.

Does it handle long times over an hour?

Yes. Use the hours field for runs over 60 minutes, such as a half marathon or marathon.

Is this an average across the whole run?

Yes. It is your overall average pace, not a per-kilometre split. Splits can vary within the same average.

Can I share a calculation?

Yes. Use Share to copy a link that reopens the calculator with the same distance and time.

Running pace calculator

Enter the distance you ran in kilometres and the time it took as hours, minutes, and seconds. The calculator shows your pace per kilometre, your pace per mile, and your average speed.

Use it to turn a distance and a time into a pace per km and per mile, plus speed.

Pace per km

5:30 /km

Pace per mile: 8:51 /mi
Speed: 10.9 km/h

The result updates as you type. The headline is your pace per kilometre in minutes and seconds; the others give the per-mile pace and your speed.

How does it work?

The per-mile pace multiplies the per-kilometre pace by 1.609344. Speed is distance divided by the time in hours.

Running pace formula

\text{pace} = \frac{\text{total seconds}}{\text{distance}},\quad \text{speed} = \frac{d}{t_{\text{hours}}}

pace: Time per kilometre, shown as m:ss.
d: Distance in kilometres.
t: Total time (hours, minutes, seconds).
speed: Average speed in km/h.

Running 5 km in 27:30 is 1650 s ÷ 5 = 330 s/km, a pace of 5:30 /km and a speed of about 10.9 km/h.

Method & sources

Distance is entered in kilometres; time is split into hours, minutes, and seconds. Pace is the average across the whole distance, not per split. The per-mile pace uses 1.609344 km per mile.

How we calculate

Distance is entered in kilometres; time is split into hours, minutes, and seconds.
Pace is the average across the whole distance, not per split.
The per-mile pace uses 1.609344 km per mile.
Speed is distance divided by the total time in hours.

Rounding

Pace is shown as minutes and seconds; speed to one decimal. The calculation uses full precision.

What this calculator does

Pace is how long it takes to cover one kilometre or mile. This calculator divides your total time by the distance to get the per-kilometre pace, scales it for miles, and works out your average speed in km/h.

How to use it

Enter the distance in kilometres.
Enter the time as hours, minutes, and seconds.
Read your pace per kilometre and per mile.
Check the average speed in km/h.

A worked example

Running 5 km in 27 minutes 30 seconds is 1650 seconds over 5 km, a pace of 5:30 per kilometre — about 8:51 per mile and roughly 10.9 km/h.

Using pace in training

Knowing your pace helps you plan race targets and keep training runs honest. Easy runs sit well above race pace; intervals dip below it. Use the per-mile figure if your event is measured in miles.

Common mistakes

Entering minutes in the seconds field, or vice versa.
Mixing up kilometres and miles for the distance.
Expecting a single average pace to reflect an uneven effort.

When it's useful

After a run to see your pace, or before a race to plan the pace you need for a target finish time.
