Quick Tool Overview

The Pace Calculator solves for whichever of pace, time and distance you do not know. Pace is shown in minutes per kilometre and minutes per mile at the same time, alongside the equivalent speed, and the units follow the convention of the sport you pick.

About the Pace Calculator

Enter any two of pace, time and distance and the third is calculated. Pace is shown in minutes per kilometre and minutes per mile at the same time, alongside the equivalent speed, so you never have to convert between the two conventions in your head.

Different sports quote pace differently and the calculator follows each convention: runners work in minutes per kilometre or mile, cyclists in kilometres or miles per hour, and swimmers in minutes per 100 metres or 100 yards. Switching sport changes the units but not the arithmetic, which is always the same relationship between how far, how long and how fast.

Key features of the Pace Calculator

Solve in any direction

Fill in two of the three and the calculator rearranges for the one you left blank.

Metric and imperial together

Minutes per kilometre and minutes per mile are shown at once, so you never convert in your head.

Sport-specific units

Runners work in minutes per kilometre or mile, cyclists in km/h or mph, swimmers in minutes per 100 metres or yards.

Speed shown alongside pace

The two conventions describe the same thing, and having both removes a constant source of confusion.

Same arithmetic, any sport

Switching sport changes the units but not the relationship between how far, how long and how fast.

How to use the Pace Calculator

  2. 2

    Fill in two of the three

    Enter any two of pace, time and distance and leave the third blank.

  3. 3

    Read the answer

    The missing value is calculated, with the equivalent speed and the other pace unit shown alongside it.

Frequently asked questions

They are inverses. Pace is time per unit of distance, such as 5 minutes per kilometre, while speed is distance per unit of time, such as 12 kilometres per hour. Both describe the same effort.
