In the original form, the point of the 12 minute test is to run as far as possible within 12 minutes. The test is meant to measure the condition of the person taking it and therefore it is supposed to be run at a steady pace instead of sprints and fast running.

The outcome is based on the distance the test person ran, their age and their sex. The results can be correlated with VO2 Max. It is an easy test to perform on larger groups.

The length of the run is considered to be that of a long distance run, since everything above 3 km is rated "long distance"—which means the runner will predominately use his "red", slow oxidative muscle cells.
