Track OCR’s are sprint to middle distance competitions from 25 meters and up. Individual and mixed relay events can be time trials (one person at a time) or have 2 to 24 people or more on the start line. The 100 m (10 OCR obstacles) and 400 m (12 OCR obstacles) events have established world records and have been held in Games recognised by the International Olympic Committee.

The FISO international standard OCR 100m, which qualify athletes for Guinness World Records, has been held in the Southeast Asian Games since 2019, recently in the 2023 SEA Games in Cambodia.

Track OCR is held on athletic tracks, stadiums, streets or other flat areas.  Events in popular culture include the Million Dollar Mile competition show on CBS television network in the United States.
