How long is a standard indoor athletics track lap?

A standard indoor athletics track lap is 200 metres.

Indoor tracks are commonly built with a 200 m oval, half the length of the standard outdoor track. Because space is limited inside arenas, indoor races use tighter bends and often have banked curves to help athletes maintain speed safely.

The 200 m track affects race tactics. Athletes complete more laps than they would outdoors, and the shorter straights can make overtaking difficult. Indoor championships commonly feature 60 m sprints rather than the outdoor 100 m sprint, while middle-distance races require careful counting of laps.

Some facilities have nonstandard layouts, so not every indoor running surface is exactly 200 m. The 200 m figure refers to the standard competition track used for major international indoor athletics.
