Running Pace Calculator
The calculator finds pace from time and distance. 10 km in 50 minutes is 5:00 per kilometer and 12 km/h. You can also reverse the formula: from pace the calculator finds time or distance.
This is not calories. Calories from distance are on the running calories calculator. Hours between two clock times are on the hours calculator.
Result
Enter time and distance, or pace and one of those numbers. The result will appear here.
How it works
The calculator divides time by distance. 10 km in 50 minutes is 3000 seconds over 10 km, which is 5:00 per kilometer. Speed is 12 km/h. Per mile that is 8:03, because a mile is 1.609344 km.
5 km in 22 min 30 s is 4:30 per kilometer. 22 min 30 s is 1350 seconds, and 1350 divided by 5 is 270 seconds per kilometer.
A 42.195 km marathon in 4 hours is 5:41 per kilometer. Four hours equal 14400 seconds, and 14400 divided by 42.195 is about 341 seconds per kilometer.
When you know pace and distance, the calculator multiplies pace by kilometers and shows time. A pace of 5:00 per kilometer and 10 km give 50 minutes.
When you know pace and time, the calculator divides running seconds by pace seconds and shows distance.
This is not calories and not a training plan. Calories from mass and kilometers are on the running-calories page.
Formula
pace = time / distance; time = pace × distance; distance = time / pace
The international mile is 1.609344 km. Pace is rounded to a whole second.
How to use
- Choose pace from time and distance.
- Pick 10 km from the list, or enter 10.
- Enter 50 in minutes. The result is 5:00 per kilometer.
- To get time, choose pace and distance. A pace of 5:00 and 10 km give 50 minutes.
5:00 per kilometer from 10 km in 50 minutes
50 minutes is 3000 seconds. 3000 divided by 10 km is 300 seconds, which is 5:00 per kilometer.
- 5:00
- Five minutes per kilometer. That is 12 km/h and 8:03 per mile.
- 1,609344
- Kilometers in an international mile. A 1.6 shortcut already spoils pace per mile.
- 42,195
- Kilometers in a marathon. In 4 hours the pace is 5:41 per kilometer.
