How to calculate running pace

Select Find pace, choose your distance and enter your target finish time in hours, minutes and seconds. Your average pace updates instantly in both minutes per kilometre (min/km) and minutes per mile (min/mile), ready to use with your watch.

How to calculate your finish time

Select Find time, choose the same race distance and enter your pace per kilometre or per mile. WhatPace calculates the time for that distance at a steady average pace. This is a calculation, rather than a prediction of your fitness or race performance.
