Cinder Track
A cinder track is a type of race track, generally purposed for track and field or horse racing, whose surface is composed of cinders. For running tracks, many cinder surfaces have been replaced by all-weather synthetic surfaces, which provide greater durability and more consistent results, and are less stressful on runners. The impact on performance as a result of differing track surfaces is a topic often raised when comparing athletes from different eras. Synthetic tracks emerged in the late 1960s; the 1964 Olympics were the last to use a cinder track. - Tokyo 1964 - accessed 2011-08-09 The Little 500 bicycle race at |
Race Track
A race track (racetrack, racing track or racing circuit) is a facility built for racing of vehicles, athletes, or animals (e.g. horse racing or greyhound racing). A race track also may feature grandstands or concourses. Race tracks are also used in the study of animal locomotion. A ''racetrack'' is a permanent facility or building. ''Racecourse'' is an alternate term for a horse racing track, found in countries such as the United Kingdom, India, Australia, Hong Kong, and the United Arab Emirates. Race tracks built for bicycles are known as ''velodromes''. ''Circuit'' is a common alternate term for race track, given the circuit configuration of most race tracks, allowing races to occur over several laps. Some race tracks may also be known as ''speedways'', or ''raceways''. A ''race course'', as opposed to a ''racecourse'', is a nonpermanent track for sports, particularly road running, water sports, road racing, or rallying. Many sports usually held on race tracks also can occu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track And Field
Track and field is a sport that includes athletic contests based on running, jumping, and throwing skills. The name is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. The foot racing events, which include sprints, middle- and long-distance events, racewalking, and hurdling, are won by the athlete who completes it in the least time. The jumping and throwing events are won by those who achieve the greatest distance or height. Regular jumping events include long jump, triple jump, high jump, and pole vault, while the most common throwing events are shot put, javelin, discus, and hammer. There are also "combined events" or "multi events", such as the pentathlon consisting of five events, heptathlon consisting of seven events, and decathlon cons ...

Horse Racing
Horse racing is an equestrian performance sport, typically involving two or more horses ridden by jockeys (or sometimes driven without riders) over a set distance for competition. It is one of the most ancient of all sports, as its basic premise – to identify which of two or more horses is the fastest over a set course or distance – has been mostly unchanged since at least classical antiquity. Horse races vary widely in format, and many countries have developed their own particular traditions around the sport. Variations include restricting races to particular breeds, running over obstacles, running over different distances, running on different track surfaces, and running in different gaits. In some races, horses are assigned different weights to carry to reflect differences in ability, a process known as handicapping. While horses are sometimes raced purely for sport, a major part of horse racing's interest and economic importance is in the gambling associated with ...

Scoria
Scoria is a pyroclastic, highly vesicular, dark-colored volcanic rock that was ejected from a volcano as a molten blob and cooled in the air to form discrete grains or clasts.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. It is typically dark in color (generally dark brown, black or purplish-red), and basaltic or andesitic in composition. Scoria is relatively low in density as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water. The holes or vesicles form when gases that were dissolved in the magma come out of solution as it erupts, creating bubbles in the molten rock, some of which are frozen in place as the rock cools and solidifies. Scoria may form as part of a lava flow, typically near its surface, or as fragmental ejecta (lapilli, blocks and bombs), for ins ...

All-weather Running Track
An all-weather running track is a rubberized, artificial running surface for track and field athletics. It provides a consistent surface for competitors to test their athletic ability unencumbered by adverse weather conditions. Historically, various forms of dirt, Rocks, sand, and crushed cinders were used. Many examples of these varieties of track still exist worldwide. Surfaces Starting in the late 1950s, artificial surfaces using a combination of rubber and asphalt began to appear. An artificial warm-up track was constructed for the 1956 Summer Olympics in Melbourne, Australia. During the 1960s many of these tracks were constructed; examples still exist today. In the mid-1960s Tartan tracks were developed, surfaced with a product by 3M. The name ''Tartan'' is a trademark, but it is sometimes used as a genericized trademark. This process was the first to commercialize a polyurethane surface for running tracks, though it was originally conceived for horse racing. Many Ta ...

1964 Summer Olympics
The , officially the and commonly known as Tokyo 1964 ( ja, 東京1964), were an international multi-sport event held from 10 to 24 October 1964 in Tokyo, Japan. Tokyo had been awarded the organization of the 1940 Summer Olympics, but this honor was subsequently passed to Helsinki due to Japan's invasion of China, before ultimately being cancelled due to World War II. Tokyo was chosen as the host city during the 55th IOC Session in West Germany on 26 May 1959. The 1964 Summer Games were the first Olympics held in Asia, and marked the first time South Africa was excluded due to the use of its apartheid system in sports. Until 1960, South Africa had fielded segregated teams, conforming to the country's racial classifications; for the 1964 Games the International Olympic Committee demanded a multi-racial delegation to be sent, and after South Africa refused, they were excluded from participating. The country was, however, allowed to compete at the 1964 Summer Paralympics, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little 500
The Little 500 (also known popularly as the "Little Five"), is a track cycling race held annually during the third weekend of April at Bill Armstrong Stadium on the campus of Indiana University in Bloomington, Indiana. It is attended by more than 25,000 fans each April. History The race was founded in 1951 by Howdy Wilcox Jr., executive director of the Indiana University Foundation, who modeled the race after the Indianapolis 500 automotive race, which his father had won in 1919. Racers compete in teams of four, racing relay-style for 200 laps () along a quarter-mile () cinder track. Thirty-three teams are selected in qualifications trials to compete in the main race. Money raised by the event funds scholarships for working Indiana University students. The inaugural Women’s Little 500 was held in 1988. Four members of the Kappa Alpha Theta sorority completed a qualifications run in the 1987 men’s event on their 3rd and final attempt, but failed to qualify into the field of ...
