Meaning
Working under intense time pressure in a race to finish a task before a fixed deadline runs out.
It emphasizes urgency and the risk of not finishing in time, often used when every minute counts.
Origin
The phrase draws on sports timing traditions, such as cycling, swimming, and athletics, where a competitor’s result is measured against a recorded stopwatch time rather than compared directly to another racer, effectively making the clock itself the opponent. By the mid-twentieth century the image had moved beyond sports commentary into everyday English, describing any task completed under a tight, ticking deadline.
