In sports, "DNF" stands for "Did Not Finish." This term is used to indicate that an athlete or team did not complete a race or event. Common in endurance sports like marathons and triathlons, a DNF can occur for various reasons, including injury, fatigue, or equipment failure. A DNF is significant because it affects an athlete's standings and statistics. In competitive events, finishing is often crucial for ranking and qualifying for future competitions. Athletes may also reflect on a DNF to assess their performance and make improvements for future events.
