In the United States, the form '''World's Record
was formerly more common. The term The World's Best''' was also briefly in use. The latter term is still used in
athletics events, including
track and field and
road running to describe good and bad performances that are not recognized as an official world record: either because it is not an event where
World Athletics tracks the record (e.g. the 150 m run or individual events in a
decathlon), or because it does not fulfill other rigorous criteria of an otherwise qualifying event (e.g. the
Great North Run half-marathon, which has an excessive downhill gradient). The term is also used in video game
speedrunning for the fastest achieved time in the game and category. == Sports ==
