The idiom "race against time" means to try to do something very quickly before a deadline or before it's too late. It's like running a race where time is your opponent and you have to finish before the clock runs out.
For example, if you have a project due tomorrow and you haven't started yet, you might say, "I'm racing against time to finish this project." Or if you're trying to catch a flight that's about to take off, you might say, "I'm racing against time to make it to the airport on time."
This idiom is often used when there is a sense of urgency or pressure to complete a task or achieve a goal within a limited amount of time. It can also be used to describe situations where time is running out and there is a need to act quickly to avoid a negative outcome.
