The World Athletics Relays, known as the IAAF World Relays until 2019, is an international biennial track and field sporting event held by World Athletics where teams from around the world compete in relay races, some of which are not part of the standard Olympic programme. The first three editions were set to take place in Nassau, Bahamas at the Thomas Robinson Stadium in 2014, 2015 and 2017. Originally intended as an annual event, it was later decided to happen every odd year, the same as the World Athletics Championships for which it serves as a qualification stage.
