During a relay race, members of a team take turns running, orienteering, swimming, cross-country skiing, biathlon, or ice skating parts of a circuit or performing a certain action. Relay races take the form of races and amateur games. In the Olympic games, there are types of relay races that are part of track. A swimming relay of four swimmers usually follows this strategy, second-fastest, third-fastest, slowest, then fastest. However, it is not uncommon to see either the slowest swimmer racing in the second slot, besides, many swimmers perform better in a relay than in an individual race owing to a team spirit atmosphere. As a result, relay times are typically 2–3 seconds faster than the sum of best times of individual swimmers, the three standard relays raced at the Olympics are the 4 ×100 m freestyle relay,4 ×200 m freestyle relay and 4 ×100 m medley relay. In athletics, the two standard relays are the 4 ×100 metres relay and the 4 ×400 metres relay. Traditionally, the 4 ×400 m relay finals are the last event of a track meet and it is hard to measure exact splits in a 4 ×400 relay. A4 ×400 relay generally starts in lanes for the first leg, a race organizer then puts the third leg runners into a line depending on the order in which they are running. The faster teams pass first, while the teams have to slide in to the inside lanes as they come available. 4 ×200,4 ×800, and 4 ×1600 relays exist as well, but they are rarer, especially at the school level. 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 stands on a spot predetermined in practice. The second runner opens their hand behind them after a few strides, by time the first runner should be caught up. Usually a runner will give a 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. Although some teams use second-fastest, slowest, third-fastest, then the fastest, but if a runner is better in the starting blocks than the others, he is sometimes moved to the first spot because it is the only spot that uses starting blocks. It is credited with popularizing relay racing in the sport of track & field, the worlds longest relay race is Japans Prince Takamatsu Cup Nishinippon Round-Kyūshū Ekiden, which begins in Nagasaki and continues for 1,064 kilometres
