The term 'RACE DO-OVER' is a combination of two words, 'RACE' and 'RESTART', which together refer to the concept of starting a RACE again from the beginning. This could be due to a false start, a technical issue, or any other reason that would require the RACE to be restarted. The term is often used in sports, such as running, cycling, and motor racing, but can also be applied to other activities, such as board games or video games.
