What is a stagger start in athletics?

A stagger start in athletics is a starting method used in races, particularly in track events, to ensure that all runners cover the same distance despite running on a curved track. Each athlete begins from a different position along the starting line, staggered outward from the inside lane to account for the curvature of the track. This technique allows for a fair competition, as it compensates for the varying distances each runner must travel based on their lane assignment.
