Runners are staggered in their starting positions to ensure that everyone runs the same distance. While this event is classified as a sprint, there is more scope to use tactics in the race; the fact that 400 m times are considerably more than four times a typical 100 m time demonstrates this. The world record is currently held by Wayde van Niekerk with a time of 43.03 seconds in Rio Olympic 2016 in 400m final[9]
