On an outdoor metre racetrack, the race begins on the curve and ends on the home straight , so a combination of techniques is needed to successfully run the race. A slightly shorter race, called the stadion and run on a straight track, was the first recorded event at the ancient Olympic Games. The m places more emphasis on speed endurance than shorter sprint distances as athletes predominantly rely on anaerobic energy system during the m sprint.

This enables them to stride forwards more powerfully when the race begins and start faster.
