Running pace calculator and pace chart (km and mile)
Enter a distance and elapsed time to find average pace, or look up a pace in the chart below. No account, watch connection or upload is needed.

Pace chart: min/km, min/mile, speed and finish times
Each row is a steady pace and the time it takes to cover each distance without stopping. These are arithmetic results, not race predictions.
Swipe across the table to see every column.

What a pace result means
Pace is the time needed to cover one unit of distance. A result of 5:00 per km means five minutes per kilometre, not five kilometres per hour. Speed measures distance per hour and is shown separately.
The calculation divides elapsed seconds by distance. One mile is exactly 1.609344 km. Changing units describes the same activity rather than changing the effort.
Example: 5 km in 25 minutes
25 minutes divided by 5 km gives 5:00 min/km. The same pace is approximately 8:03 min/mile and 12 km/h. Maintaining it for 10 km would mathematically take 50 minutes.
The table is not a race prediction. Terrain, stops, conditions and your ability to sustain the effort can change the actual result.
How long a distance takes at a given pace
Multiply pace by distance. At 8:00 min/km, 4 km takes 32 minutes and 5 km takes 40 minutes; that pace is 7.5 km/h, about 12:52 per mile. At 6:00 min/km, 10K takes exactly one hour.
To turn km/h into min/km, divide 60 by the speed: 10 km/h is 6:00 min/km and 12 km/h is 5:00 min/km. For miles, divide 60 by mph: 6 mph is a 10:00 mile.
The chart uses 21.0975 km for the half marathon and 42.195 km for the marathon, rounded to the second.
Elapsed time versus moving time
Use a consistent time definition when comparing logs. Elapsed time includes stops; a device may exclude them from moving time. Mixing the two can make different records look comparable.
Check distance and units too. A different distance measurement changes the average even when elapsed time stays the same. This tool calculates your inputs and does not verify GPS accuracy.
Share a workout without prescribing a target
Agree on what each friend wants to share before comparing results. Pace does not measure the value of a workout and does not need to become a target for the whole group.
Rally has its own points rules. Converting pace or distance does not change scoring or add a watch integration. You can log your activity in the app and keep this calculation as a separate reference.
