In athletics, a "relay" refers to a race in which teams of runners compete by passing a baton between them, typically over a set distance. Each team member runs a predetermined leg of the race before handing off the baton to the next runner. The smoothness and speed of the baton exchange can significantly impact the overall performance. Common relay events include the 4x100 and 4x400 meter relays, which require coordination, teamwork, and speed. Success in relay races represents the culmination of individual effort and collective strategy.
