4 × 400 Metres Relay
The 4 × 400 metres relay or long relay is an athletics track event in which teams consist of 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 leg and the first bend of the second leg are 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. The slightly longer 4 × 440 yards relay was a formerly run British and American event, until metrication was completed in the 1970s. 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 t ...

Jamaica
Jamaica (; ) is an island country situated in the Caribbean Sea. Spanning in area, it is the third-largest island of the Greater Antilles and the Caribbean (after Cuba and Hispaniola). Jamaica lies about south of Cuba, and west of Hispaniola (the island containing the countries of Haiti and the Dominican Republic); the British Overseas Territory of the Cayman Islands lies some to the north-west. Originally inhabited by the indigenous Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494. Many of the indigenous people either were killed or died of diseases, after which the Spanish brought large numbers of African slaves to Jamaica as labourers. The island remained a possession of Spain until 1655, when England (later Great Britain) conquered it, renaming it ''Jamaica''. Under British colonial rule Jamaica became a leading sugar exporter, with a plantation economy dependent on the African slaves and later their des ...

4 × 100 Metres Relay
The 4 × 100 metres relay or sprint relay is an athletics track event run in lanes over one lap of the track with four runners completing 100 metres each. The first runners must begin in the same stagger as for the individual 400 m race. Each runner carries a relay baton. Before 2018, the baton had to be passed within a 20 m changeover box, preceded by a 10-metre acceleration zone. With a rule change effective November 1, 2017, that zone was modified to include the acceleration zone as part of the passing zone, making the entire zone 30 metres in length. The outgoing runner cannot touch the baton until it has entered the zone, and the incoming runner cannot touch it after it has left the zone. The zone is usually marked in yellow, frequently using lines, triangles or chevrons. While the rule book specifies the exact positioning of the marks, the colours and style are only "recommended". While most legacy tracks will still have the older markings, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metrication
Metrication or metrification is the act or process of converting to the metric system of measurement. All over the world, countries have transitioned from local and traditional units of measurement to the metric system. This process began in France during the 1790s, and is still continuing more than 200 years later, with the modern International System of Units, as the metric system has not yet been fully adopted in all countries and areas. Overview Most countries now have the metric system as their official system of weights and measures. Some have adopted it as their official system but have not yet completed the process of metrication. Some others have not made any commitment to adopting it. There is not a general consensus in the sources as to the number of countries that fall into each of these categories. According to a 2011 doctoral dissertation by Hector Vera, as of 2010, a total of seven countries had not "adopted the metric system as their exclusive system of measur ...
