Middle distance track event

Middle distance track events are track races longer than sprints up to (and arguably including) 5000 meters. Biological factors that go primarily into a middle distance racer are developed fast and type 1 slow twitch muscles, adrenaline (usually for the final kick), anaerobic respiration (bringing it in after the final kick), racing tactics, and aerobic conditioning. The 1500m has been estimated to require an equal contribution from fast and slow twitch muscles.
