400m Relay
Overview
The 400m relay is a short-distance relay event on the athletics track in which four runners each run 100m and pass a baton in turn to complete the race. The official event name is the 4×100m relay, and in Korea it is also widely called the 400m relay to emphasize the total distance of 400m. It is a representative cooperative team event in which accuracy of baton passing and team coordination, rather than pure individual speed, decide the outcome.

Competition Format and Rules
- Four runners divide the 100m segments and run, and each runner slows down within their own lane after passing the baton to the next runner.
- The baton must be passed from hand to hand, and if dropped, the runner must pick it up personally.
- Baton passing must take place only within the designated take-over zone (exchange zone); passing outside the zone results in disqualification.
- Each team must run only in its assigned lane, and lane infringement results in disqualification or a penalty.
- Ranking is determined by the order of crossing the finish line, and photo-finish systems are used for the final decision.
Baton Passing and Take-Over Zone
The baton exchange zone is set to approximately 30m (according to international regulations) of each 100m segment. The runner passing the baton (the incoming runner) maintains top speed at the start of the zone, while the runner receiving it (the outgoing runner) accelerates with the start signal. The ideal pass is for both to meet hands while near top speed; for this, the receiving runner uses a blind pass, in which they run forward without looking back and extend a hand backward. It is common to alternate the hand holding the baton between right and left, and the action of the receiving runner opening their palm to indicate position just before the exchange is considered a key technique.
Track Configuration and Lane Assignment
The 400m track mixes straight and curved sections, so lane 1 is the narrowest and has the smallest curve radius, making it disadvantageous. Considering speed loss on curves, runner placement varies according to team strategy. Generally, the first runner is an athlete with quick start reaction, the second runner an athlete with excellent curve-running ability, the third runner an athlete with high top speed, and the fourth runner an athlete with good finishing ability. Unlike individual events, the relay is greatly affected in overall record by maintaining rhythm through the curved sections.
Runner Composition and Strategy
- 1st runner: start block reaction and initial acceleration ability are important.
- 2nd runner: curve-running technique and stable baton reception are required.
- 3rd runner: top speed and ability to maintain exchange rhythm are key.
- 4th runner: finish-line sprint and ability to handle pressure situations determine the outcome.
Team strategy varies greatly according to exchange point placement, start timing, and baton-passing rhythm. Since one mistake can overturn the entire ranking, unconscious coordination and trust built through repeated training are more important than anything else.
World Records and Major Competitions
The men's 4×100m world record is 36.84 seconds, set by the Jamaican national team at the 2012 London Olympics, and the women's record is 40.82 seconds, set by the United States at the same competition. It is held as an official event at the World Athletics Championships, the Olympics, the Diamond League, and others. Korea has consistently competed for medals at the Asian Games and Asian Championships, with the 1986 Seoul Asian Games gold medal, etc., cited as representative achievements.
400m Relay in Korea
In Korea, it has become a representative group event at elementary, middle, and high school sports competitions and sports days, and is called the highlight of school athletics competitions. It is operated as an official event at the National Sports Festival, the National Junior Sports Festival, etc., and university and corporate track and field athletes form the national team. Recently, more teams are systematizing baton-passing technique training and introducing sports science such as high-speed cameras and motion analysis. It is also adopted as an event at local residents' sports festivals, playing a role in expanding the base of recreational sports.
Recent Trends
- With the 2024 Paris Olympics and the 2025 World Athletics Championships (Tokyo) as opportunities, interest in relay events has increased, and countries are using AI and motion capture technology to analyze baton exchange zones.
- World Athletics is continuously revising take-over zone rules and video review standards, improving the system in the direction of reducing judging controversies.
- Korea is carrying out a generational change of its national relay team in 2025, training with sprint prospects at the center with the goal of improving the 4×100m record.
- In school sports days and recreational sports settings, record-measuring apps and electronic scoreboards are spreading, and the 400m relay is being reexamined as a festival-style event.
- As sports science-based exchange timing data analysis spreads even to amateur teams, training methods are trending from experience-centered to data-centered.
