Finish line
The end line of a ralay race
The starting point in a race is called the starting line. The end point of a race is called the finish line.
The Formula 1 finish line is significant because it marks the point where the race officially ends and determines the winner based on which driver crosses it first. The first driver to cross the finish line is declared the winner of the race.
The first to cross the finish line
An arms race, an eating contest, a swimming race (the race is finished when a swimmer touches the wall, so they don't pass anything in order to finish).
A swimming race, although some would say touching the wall is like crossing the finish line.
The person who crossed the finish line last.
