Pace calculator.
Work out your running pace from a distance and a time. See your pace per mile and per kilometre, and your speed in miles and kilometres per hour.
Distance and time
LivePace is time divided by distance. Enter the distance in miles and the time in minutes; both pace units and speeds are shown.
Pace per mile
9:02 /mi
minutes and seconds per mile
A pace and speed estimate from the distance and time you enter. Calculations run in your browser; nothing you enter is stored.
How it works
Time divided by distance
Your pace is simply how long it takes to cover one unit of distance. Divide your total time by the distance to get it: 28 minutes over 3.1 miles is about 9 minutes per mile. The calculator also converts that to a per-kilometre pace and to speed.
Pace and speed are two views of the same thing. Pace, in minutes per mile or km, is what most runners track; speed, in mph or km/h, is the same effort expressed the other way round.

What pace is, how it relates to speed, and how to use it in training and races.
What is running pace?
Running pace is the time it takes to cover a set distance, usually written as minutes and seconds per mile or per kilometre. A 9:00 per mile pace means each mile takes nine minutes. It is the most common way runners measure and plan effort.
Lower numbers mean faster running, which is the opposite of speed, where higher is faster.
Pace versus speed
Pace and speed describe the same run. Speed in miles or kilometres per hour tells you distance covered in an hour; pace tells you time spent per unit of distance. To convert, divide 60 by your pace in minutes to get speed, or 60 by your speed to get pace.
Treadmills usually show speed, while watches and race plans usually show pace, so it helps to read both.
Using pace in training
Different sessions call for different paces: easy runs are comfortably conversational, tempo runs are sustained and harder, and intervals are fast with recovery. Knowing your paces keeps easy days easy and hard days hard.
Predict a race time by holding a target pace for the full distance, and use the per-km and per-mile views to match whatever your course is marked in.
Mile and kilometre
A mile is about 1.609 kilometres, so a per-mile pace is always a larger number than the per-km pace for the same effort. The table above lines the two up for common paces.
If you race in kilometres but train by miles, convert your goal pace so your easy and hard efforts stay consistent.
The formula
Time over
distance.
Pace is total time divided by distance; speed is distance divided by time. A mile is about 1.609 km.

Pace questions.
How do I calculate running pace?
+
Divide your total time by the distance. Running 3.1 miles in 28 minutes is 28 divided by 3.1, about 9:02 per mile. The calculator also shows the per-km pace and your speed.
What is the difference between pace and speed?
+
Pace is time per distance, like minutes per mile, where lower is faster. Speed is distance per time, like miles per hour, where higher is faster. They describe the same run.
How do I convert pace per mile to per km?
+
Divide the per-mile pace by 1.609, since a mile is about 1.609 km. A 9:00 per mile pace is about 5:36 per km.
What is a good running pace?
+
It depends on fitness and distance. Many recreational runners sit around 9 to 11 minutes per mile on easy runs. Use your own pace as the baseline and aim to improve it over time.
Is this pace calculator free?
+
Yes. It is completely free with no sign-up, and every calculation runs locally in your browser, so nothing you enter is stored or sent anywhere.
