“Final sprint” is a metaphorical expression that comes from running or racing. In a race, the sprint is a short, intense burst of speed near the end to finish strong. When used outside of a racing context, “final sprint” refers to the last, intense effort to complete a task, project, or goal. It often implies that someone is working hard, with a sense of urgency, to finish something before a deadline or event.
For example, if a project deadline is approaching, a team might be in the “final sprint” to complete all the remaining tasks. It conveys a sense of focused, high-energy effort in the last phase of a process.
“During the last week of the marathon training, the runners focused on their final sprint, pushing their limits to build endurance and speed for the race.”
