During a relay race, members of a team take turns swimming or running (usually with a baton in the latter) parts of a circuit or performing a certain action. Swimming is the movement by humans or animals through Water, usually without artificial assistance Running is a means for an animal to move on Foot. It is defined in Sporting terms as a Gait in which at some point all feet are off the ground Relay races take the form of professional races and amateur games. In the Olympic games, there are several types of relay races that are part of track and field. The Olympic Games is an international Multi-sport event established for both summer and winter games

Based on the speed of the runners, the generally accepted strategy used in setting up a 4 person relay team is: second fastest, third fastest, slowest, then fastest (anchor). A Strategy is a long term plan of action designed to achieve a particular goal, most often "winning Each segment of the relay (the distance run by one person) is referred to as a leg.

A swimming relay order follows a slightly different strategy. Usually, the slowest swimmer races in the second slot, creating an order as follows: second fastest, slowest, third fastest, and then fastest.

Each runner must hand off the baton to the next runner within a certain zone, usually marked by triangles on the track. In sprint relays, runners typically use a "blind handoff", where the second runner stands on a spot predetermined in practice and starts running when the first runner hits a visual mark on the track (usually a smaller triangle). Sprints are short running races in athletics. They are roughly classified as events in which top runners will not have to "pace themselves" but can run as fast as The second runner opens his/her hand behind her after a few strides, by which time the first runner should be caught up and able to hand off the baton. Usually a runner will give an auditory signal, such as "Stick!" repeated several times, for the recipient of the baton to put out his hand. In middle-distance relays or longer, runners begin by jogging while looking back at the incoming runner and holding out a hand for the baton.

Two runners prepare to exchange the baton.

In athletics, the two standard relays are the 4x100 meter relay and the 4x400 meter relay. Traditionally, the 4x400 meter relay finals are the last event of a track meet, and is often met with a very enthusiastic crowd, especially if the last leg is a close race. It should be noted that it is hard to measure exact splits in a 4x400 (or a 4x100) relay. For example, if a team ran a 3:00 4x400, it does not mean every runner on the team has to run a 45 second open 400, because a person starts accelerating before he/she has the baton, therefore allowing for slightly slower overall open 400 times. 400 m is a common Track running event It is the longest common sprint distance A 4x400 relay generally starts in lanes for the first leg, including the handoff. The second leg then proceeds to run in lanes for the first 100 meters, after which point the runners are allowed to break into the first lane on the backstretch, as long as they do not interfere with other runners. A race organizer then puts the third leg runners into a line depending on the order in which they are running (with the first place closest to the inside).

4x200, 4x800, and 4x1600 relays exist as well, but they are more rare, especially at the high school level, where schools generally have only one or two competitive strong runners in such events.

A team may be disqualified from a relay for:

• Losing the baton
• Making an improper baton exchange
• Making two false starts (or in some cases only one)
• Improperly overtaking another competitor
• Preventing another competitor from passing
• Willfully impeding, improperly crossing the course, or in any other way interfering with another competitor

The largest relay event in the world is the Penn Relays, which attracts over 15,000 competitors annually on the High School, Collegiate and Professional levels, and over its three days attracts upwards of 100,000 spectators. In sports a false start is a movement by a participant before (or in some cases after being signaled or otherwise permitted by the rules to start Penn Relays (also Penn Relays Carnival) is the oldest and largest Track and field competition in the United States hosted annually since April 21 1895 It is credited with popularizing Relay Racing in the sport of Track & Field.

The world's largest series of relay races (in terms of number of races) is the Ragnar Relay Series. There are Ragnar Relays in Utah, Arizona, Minnesota, and Washington State. The world's longest relay race is Japan's Prince Takamatsu Cup Nishinippon Round-Kyūshū Ekiden, which begins in Nagasaki and continues for 1064 km. The Prince Takamatsu Cup Nishinippon Round-Kyushu Ekiden (九州一周駅伝 Kyūshū isshū Ekiden) has been an annual race in Japan since 1951 ( is the Capital and the largest city of Nagasaki Prefecture in Japan.

Long Distance Relay Races: Becoming increasingly popular with long-distance and marathon runners, a long distance relay race typically has runners traveling from 5 to 10 kilometer distances per leg and several legs per race. A race can be run over the course of a day, or may span two or more days with participants running throughout the night. Two examples of a long distance relay race include (in Canada) the Shore to Shore Relay Race which runs 305 kilometers over two days with six to twelve runners, and (in the U. S. A. ) the Hood to Coast relay race which takes runners from the top of Oregon's Mt. Hood to the Pacific Ocean in Seaside Oregon (315 km. ). Three newer 200-mile relay races in the US that emphasize scenic rural routes are the Wild West Relay in Colorado, the Green Mountain Relay in Vermont and the Texas Independence Relay in Texas. The most exciting long distance relay run is a true team effort. It is Europe's longest relay run event RoParun from Paris, France to Rotterdam, The Netherlands. Bridging a distance of 360 miles / 530 km within a timeframe of anywhere between 35 and 50 hours non stop, this ever growing event raises millions of Euros for charity.

Medley relay

Medley relay events are also occasionally held in track meets, usually consisting of teams of four runners running progressively longer distances. The Distance Medley Relay consists of four legs run at distances of 1200, 400, 800, and 1600 meters. The Sprint Medley Relay usually consists of four legs run at distances of 400, 200, 200, and 800 meters, though a more uncommon variant of 200, 100, 100 and 400 meters (Sometimes called a Short Sprint Medley) also exists. See also Swedish relay. Swedish relay is an athletics track event in which teams comprise four runners

In medley swimming, each swimmer uses a different stroke (in this order): backstroke, butterfly, breaststroke, and freestyle. Medley is a combination of four different Swimming styles into one race The backstroke, also sometimes called the back crawl, is one of the four The butterfly, ( fly for short is a swimming stroke swum on the breast with both arms moving simultaneously Breaststroke is a Swimming style swum on the Breast. It is the most popular recreational style due to its stability and the ability to keep the head out of the Freestyle is an unregulated Swimming style used in swimming competitions according to the rules of FINA.
