Formula
How this is calculated
This calculator takes two inputs — the distance you ran in kilometres and your total finishing time in minutes — and derives three related numbers. Pace is simply time divided by distance, giving minutes per kilometre; for example 50 minutes over 10 km yields 5.0 min/km, which is displayed as the more readable 5:00 (mm:ss) per kilometre. Pace is the inverse of speed, so it falls as you run faster.
Speed in km/h is found by dividing 60 (minutes in an hour) by the pace in min/km: a 5:00/km pace equals 12 km/h. Pace per mile is the km pace multiplied by 1.609344, the exact number of kilometres in a statute mile, then shown again as mm:ss.
The race-distance bars apply your current pace to the standard 5K, 10K, half-marathon (21.0975 km) and marathon (42.195 km) distances, projecting an even-effort finish time for each. These projections assume a perfectly constant pace and flat terrain; in reality fatigue, hills, wind and heat usually slow longer efforts, so treat the longer-distance estimates as optimistic targets rather than guarantees.
Examples
| Input | Result |
|---|---|
| 10 km in 50 minutes | Pace 5:00 /km, speed 12 km/h |
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.
