any cards; it is his or her job only to disqualify the offending walker. Disqualifications are routine at the elite level, such as the famous case of Jane Saville, disqualified within sight of a gold medal in front of her home crowd in the 2000 Summer Olympics, or Yet Lyu, disqualified 20 metres before the finish line at the 2017 World Championships in Athletics. Beginning Racewalking developed as one of the original track and field events of the first meeting of the English Amateur Athletics Association in 1880. The first racewalking codes came from an attempt to regulate rules for popular 19th-century long-distance competitive walking events, called pedestrianism. Pedestrianism had developed, like footraces and horse racing, as a popular working class British and American pastime, and a venue for wagering. Walkers organised the first English amateur walking championship in 1866, which was won by John Chambers, and judged by the "fair heel and toe" rule. This rather vague code was the basis for the rules codified at the first Championships Meeting in 1880 of the Amateur Athletics Association in England, the birth of modern athletics. With football (soccer), cricket, and other sports codified in the 19th century, the transition from professional pedestrianism to amateur racewalking was, while relatively late, part of a process of regularisation occurring in most modern sports at this time. The Walk was included at the 1876 to 1879 National Association of Amateur Athletes of America Championships. Olympics Racewalking is an Olympic athletics (track and field) event with distances of 20 kilometres for both men and women and 50 kilometres for men only. Racewalking first appeared in the modern Olympics in 1904 in the form of a half-mile (804.672m) walk in the all-round competition, the precursor to the 10-event decathlon. In 1908, stand-alone 1,500m and 3,000m racewalks were added, and, excluding 1924, there has been at least one racewalk (for men) in every Olympics since. Women's racewalking became an Olympic event in 1992, following years of active lobbying by female internationals. A World Cup in racewalking is held biennially, and racewalk events appear in the World Athletics Championships, the Commonwealth Games and the Pan American Games, among others. World Race Walking Challenge Since 2003, the IAAF has organised the IAAF Race Walking Challenge, an annual worldwide competition series in which elite athletes accumulate points for the right to compete in the IAAF Race Walking Challenge Final and
