Running Pace Calculator

Pace is the time it takes to run one kilometre or mile. Choose pace, finish time or distance, then enter the other two values. The calculator uses time = pace × distance to find the missing value. Use the menu next to the pace field to switch between kilometres and miles.

Use it to check the pace needed for a goal time, the time needed for a planned run, or how far you can run in a set time. To plan different paces for different parts of a race, use the Race Pace Calculator.

How to calculate pace from a finish time

Choose Find Pace. A 10 km run in 50:00 takes 3,000 seconds. Divide by 10 to get 300 seconds per kilometre: 5:00 min/km, or approximately 8:03 min/mile.

How to calculate finish time or distance

Choose Find Time to multiply pace by distance: 5:30 min/km over 10 km gives 55:00. Choose Find Distance to divide time by pace: 45:00 at 6:00 min/km gives 7.5 km. Use a consistent unit for both distance and pace.

Converting min/km to min/mile

A mile is 1.609344 km. Multiply seconds per kilometre by 1.609344 to get seconds per mile; divide for the reverse conversion. For example, 6:00 min/km is approximately 9:39 min/mile. Enter 5:30 for five minutes and thirty seconds, not 5.30. Decimal minutes mean something different.

Choose the right pace calculator

This calculator works with numbers you already know. To estimate a finish time at another distance from a recent result, use the Race Time Predictor. To find paces for easy runs and harder workouts, use the Training Pace Calculator. A pace chart or race estimate does not account for weather, the course or your fuel on the day.
