Running pace calculator

Enter a race distance and finish time to get pace per kilometre and per mile plus average speed in both unit systems.

Enter a distance and finish time.

Pace is total time over distance and speed is distance over total time; the tool derives both unit systems from the same inputs, so the four numbers always agree. This is the arithmetic of your run, not a race prediction: no elevation, weather, pacing fade, or course turns are priced in.
