Pace Calculator

Pace

This calculator is used for calculations regarding your pace while exercising. When walking, running, cycling or swimming, you may want to keep track of the speed with which you travel distances. Knowing your average pace helps you predict your final time for that race you are training for. It may also function as an indicator for personal growth. The formulas used to calculate the values, along with explanations and examples, are listed below.

Formulas

Calculate pace from time and distance

The text uses kilometers instead of miles, but the same principle can be applied for miles

Distance = 10 kilometers

Time in hours = 1:05:12

Time in seconds = 1hour*60*60 + 5minutes*60 + 12seconds = 3912 seconds.

Time in minutes = 3912s / 60 = 65.2 minutes

Divide both numerator and denominator with 10 to get the minutes per kilometer

This results in 6.52 minutes per kilometer.

To convert the decimal to time-readable notation (mm:ss) the decimal is multiplied by 0.6: 0.52*0.6 = 0.312

The pace in mm:ss notation is 6:31 min/km.

Calculate pace from speed and vice versa

You may know your speed (12km/h) but not your pace (5min/km). For the sake of simplicity kilometers are used, but the same principle holds for miles. Speed and pace are each others reciprocal, also known as inverse. This is because speed = distance / time and pace = time / distance.

Example

Speed = 12km/h

1 hour = 60 minutes

12km/h = 12km/60min

Divide both numerator and denominator with 12 to get per how many minutes one kilometer is traveled = 1km/5min.

Pace is the reciprocal of speed and thus pace = 5min/km.
