Genre with Athletics. Athletics is a group of sporting events that involves competitive running, jumping, throwing, and walking. The most common types of athletics competitions are track and field, road running, cross-country running, and racewalking. The results of racing events are decided by finishing position, while the jumps and throws are won by the athlete that achieves the highest or furthest measurement from a series of attempts. The simplicity of the competitions, and the lack of a need for expensive equipment, makes athletics one of the most common types of sports in the world. Athletics is mostly an individual sport, with the exception of relay races and competitions which combine athletes' performances for a team score, such as cross country. Organized athletics are traced back to the Ancient Olympic Games from 776 BC. The rules and format of the modern events in athletics were defined in Western Europe and North America in the 19th and early 20th century, and were then spread to other parts of the world. Most modern top level meetings are held under the auspices of World Athletics, the global governing body for the sport of athletics, or its member continental and national federations. The athletics meeting forms the backbone of the Summer Olympics. The foremost international athletics meeting is the World Athletics Championships, which incorporates track and field, marathon running and race walking. Other top level competitions in athletics include the World Athletics Cross Country Championships and the World Athletics Road Running Championships. Athletes with a physical disability compete at the Summer Paralympics and the World Para Athletics Championships. Initially, the term described athletic contests in general – i.e. sporting competition based primarily on human physical feats. In the 19th century, the term athletics acquired a more narrow definition in Europe and came to describe sports involving competitive running, walking, jumping and throwing. This definition continues to be prominent in the United Kingdom and the former British Empire. Related words in Germanic and Romance languages also have a similar meaning. In many parts of North America, athletics is commonly understood as encompassing sports in general, aligning with its historical usage. The term "athletics" is seldom used specifically to denote the sport of athletics in this region. Instead, "track and field" is the preferred term used in the United States and Canada to describe athletics events, which include race-walking and marathon running. Athletic contests in running, walking, jumping and throwing are among the oldest of all sports and their roots are prehistoric. Athletics events were depicted in the Ancient Egyptian tombs in Saqqara, with illustrations of running at the Heb Sed festival and high jumping appearing in tombs from as early as of 2250 BC. The Tailteann Games were an ancient Celtic festival in Ireland, founded c. 1800 BC, and the thirty-day meeting included running and stone-throwing among its sporting events. The original and only event at the first Olympics in 776 BC was a stadium-length running event known as the stadion. This later expanded to include throwing and jumping events within the ancient pentathlon. Athletics competitions also took place at other Panhellenic Games, which were founded later around 500 BC. The Cotswold Olympic Games, a sports festival which emerged in 17th century England, featured athletics in the form of sledgehammer throwing contests. Annually, from 1796 to 1798, L'Olympiade de la République was held in revolutionary France, and is an early forerunner to the modern Olympic Games. The premier event of this competition was a running event, but various ancient Greek disciplines were also on display. The 1796 Olympiade marked the introduction of the metric system into the sport. Athletics competitions were held about 1812 at the Royal Military College, Sandhurst, and in 1840 in Shrewsbury, Shropshire at the Royal Shrewsbury School Hunt. The Royal Military Academy at Woolwich held an organised competition in 1849, and a regular series of closed meetings open only to undergraduates, was held by Exeter College, Oxford, from 1850. The annual Wenlock Olympian Games, first held in 1850 in Wenlock, England, incorporated athletics events into its sports programme.
