This calculator uses Jack Daniels" formula for calculating "VDOT" ( V̇O2max) from a race performance, which is not the same thing as VO2max, but is somewhat related.
You can use VDOT to compare performances or to get training paces from (see Jack Daniels" calculator).
It is recommended to use a race distance between 1500 m and 50 km.
Distances can be entered as e.g. "5k", "1mi", "400yds", "Marathon", "Half Marathon", or simply "1000m" or "2.5km".
Time and pace can be entered as e.g. "30m", "7m30s", "4h30m", or (HH:)MM:SS.
This calculator "splits" the above distance into smaller chunks below, and calculates how fast each part of the distance was covered, on average. It is very likely that the speed varied, which means that some parts were even faster than this.
Distances can be entered as e.g. "5k", "1mi", "400yds", "Marathon", "Half Marathon", or simply "1000m" or "2.5km".
Time and pace can be entered as e.g. "30m", "7m30s", "4h30m", or (HH:)MM:SS.

Welcome to our running pace converter calculator. It allows you to perform online conversions between miles and kilometers, speed, and pace. You can enter the pace in miles to find out how many this pace is in kilometers.
The pace converter will be useful to you if you plan to participate in races in Europe where the metric system is accepted – the distance of the marathon in kilometers and meters. If you are planning to run Marathon or Half Marathon in the United States, you can easily convert kilometers to miles to determine your pace or speed in minutes per mile.
