50 min for 10 km: P = 5 min/km
How it works
Running pace tells you how much time it takes to cover 1 kilometre. It works by dividing the total time by the total distance, so if you know how long a run took and how far you went, you can find the average time spent on each kilometre. This is useful because it gives a standard way to compare runs of different lengths or different runners.
When to use it
Use this formula when you want to convert a run’s total time and distance into a comparable pace, such as for training logs, race analysis, or setting target speeds. It is also helpful when comparing performances on different routes.
Worked example, step by step
A runner completes 8 km in 40 min. P = t / d P = 40 / 8 P = 5 So the running pace is 5 min/km.
Common mistakes to avoid
- dividing distance by time instead of time by distance
- mixing units, such as using minutes with miles while the answer is expected in min/km
- forgetting that pace is an average over the whole run, not the speed at every moment

Eliud Kipchoge's sub-2-hour marathon required an astonishing 2:50 min/km pace for 42.2 km straight.
