About this calculator
Running pace tells you how long it takes to cover one kilometer, expressed as minutes and seconds per kilometer. It is the most common way runners measure effort because it stays consistent regardless of total distance, making it easy to plan training runs and races. This calculator divides your total time by distance to get pace, then converts that into speed and pace per mile.
Pace and speed are two sides of the same number: a faster pace (smaller min/km) means a higher speed in km/h. Use pace to set targets — for example, holding 5:00 min/km for a 10 km equals a 50-minute finish. Track your pace across workouts to gauge fitness improvements and to pace races so you do not start too fast.
Frequently asked questions
Divide your total time in minutes by the distance in kilometers. The result is minutes per kilometer, usually shown as mm:ss.
Pace is time per distance (min/km) while speed is distance per time (km/h). A lower pace number means a higher speed.
Multiply your pace per kilometer by 1.609, since one mile equals about 1.609 kilometers.
