Calculate the average running speed from the total distance of run in metres and the elapsed time of a run.

This calculator's running speed results are in metres per second and converted to kilometres and miles per hour.

Example Calculation

run distance = 100 metres
elapsed time = 17.34 seconds

First, divide the distance by the amount of time to get the speed per second;

100 ÷ 17.34 = 5.7670126874279123414071510957324 rounded to 5.767.

Your running pace is 5.767 metres per second.

Convert to kilometres per hour

one hour = minutes
one minute = 60 seconds

60 * 60 = 3600

There are 3600 seconds in one hour

one kilometre = 1000 metres

Divide the time(seconds) by distance(metres);

3600 ÷ 1000 = 3.6

To convert to kilometres per hour, multiply the metres per second by 3.6

5.767 * 3.6 = 20.761

5.767 metres per second. = 20.761 kilometres per hour
