4 × 400 metres relay
The 4 x 400 metres relay or long relay is an athletics track event in which teams comprise four runners who each complete 400 metres or one lap. It is traditionally the final event of a track meet. At top class events, the first 500 metres is run in lanes. Start lines are thus staggered over a greater distance than in an individual 400 metres race; the runners then typically move to the inside of the track.
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 x 100 m relay, runners in the 4 x 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 rolling 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.
Records
Note: The IAAF announced on 12 August 2008 that they had rescinded the world record of 2:54.20 set by the USA (Jerome Young, Antonio Pettigrew, Tyree Washington, Michael Johnson) on 22 July 1998 after Pettigrew admitted to using human growth hormone and EPO between 1997 and 2003.[2]
Note: The IAAF rejected a time of 3:01.96 set by the USA (Kerron Clement, Wallace Spearmon, Darold Williamson, Jeremy Wariner) on 16 September 2006 as no post-race EPO analysis was performed.
