Middle Distance

Middle distance track events are track races longer than sprints up to (and arguably including) 5000 metres.

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
• aerobic conditioning

The 1500m has been estimated to require an equal contribution from fast and slow twitch muscles.
