4 × 400 metres relay

Relay race runners typically carry a relay baton which they must transfer between teammates. Runners have a 20 m box (usually marked with blue lines) in which to transfer the baton. The first transfer is made within the staggered lane lines; for the second and third transfers, runners typically line up across the track despite the fact that runners are usually running in line on the inside of the track. This prevents confusion and collisions during transfer. Unlike the 4 × 100 m relay, runners in the 4 × 400 typically look back and grasp the baton from the incoming runner, due to the fatigue of the incoming runner, and the wider margins allowed by the longer distance of the race. Consequently, disqualification is rare. As runners have a running start, split times cannot be compared to individual 400 m performances. Internationally, the U.S. men's team has dominated the event, but have been challenged by Jamaica in the 1950s and Britain in the 1990s. The current men's Olympic champions are from the United States. According to the IAAF rules, world records in relays can only be set if all team members have the same nationality. Mixed Mixed-sex 4 × 400 metres relays were introduced at the 2017 IAAF World Relays, with the IAAF first recognizing a world record in that event at the 2019 World Athletics Championships. In March 2022 World Athletics Council decided a set order – man, woman, man, woman – at future championships. Eventually, the format was added to the Olympics, starting with the Tokyo Olympics in 2021. ==Records==

World records Note: The IAAF rescinded a time of 2:54.20 set at Uniondale on 22 July 1998 by the United States (Jerome Young, Antonio Pettigrew, Tyree Washington, Michael Johnson) on 12 August 2008 after Pettigrew admitted to using human growth hormone and EPO between 1997 and 2003. Note: The above world record was bettered by three teams at the 2018 NCAA Division I Championship on 10 March 2018 at the Gilliam Indoor Track Stadium in College Station, United States: • 3:00.77 by the USC team of Zach Shinnick, Rai Benjamin, Ricky Morgan Jr., Michael Norman). This time was not record-eligible because Benjamin was a citizen of Antigua & Barbuda, and the others are United States citizens. Benjamin has since switched to represent the United States. • 3:01.39 by the Texas A&M team of Ilolo Izu, Robert Grant, Devin Dixon and Mylik Kerley. All four runners represent the United States, and World Athletics currently lists this as the NACAC area record, but it has not been ratified as the world record. • 3:01.43 by the Florida team of Kunle Fasasi, Grant Holloway, Chantz Sawyers, and Benjamin Lobo Vedel. This time was not record-eligible because Fasasi represents Nigeria, Holloway represents the United States, Sawyers represents Jamaica, and Vedel represents Denmark. Note: The above world record was bettered in a time of 3:21.75 by the University of Arkansas team of Amber Anning, Joanne Reid, Rosey Effiong, and Britton Wilson at the 2023 NCAA Division I Indoor Championship on 11 March 2023 in Albuquerque, New Mexico, United States. This time was not record-eligible because Anning was a citizen of Great Britain, Reid was a citizen of Jamaica, and Effiong and Wilson were United States citizens.
