Randonneuring (also known as Audax in the UK, Australia and Brazil) is a long-distance cycling sport with its origins in audax cycling. In randonneuring, riders attempt courses of 200km or more, passing through predetermined "controls" (checkpoints) every few tens of kilometres. Riders aim to complete the course within specified time limits, and receive equal recognition regardless of their finishing order. Riders may travel in groups or alone as they wish, and are expected to be self-sufficient between controls. A randonneuring event is called a randonnée or brevet, and a rider who has completed a 200km event is called a randonneur. The international governing body for randonneuring is Audax Club Parisien (ACP), which works with other randonneuring organisations worldwide through Les Randonneurs Mondiaux (RM). Randonneuring is popular in France, and has a following in the Netherlands, Belgium, the United Kingdom, Italy, Australia, the United States, Canada, Brazil, Ireland, India, Indonesia, Korea, Japan and Malaysia. In the late nineteenth century Italy, day-long "challenge" sports became popular. Participants aimed to cover as much distance as possible and prove themselves audax ("audacious"). The first recorded audax cycling event took place on June 12, 1897, when twelve Italian cyclists attempted the challenge of cycling from Rome to Naples, a distance of 230 kilometres (140mi), during daylight hours. Similar events became popular elsewhere, and in 1904 French journalist Henri Desgrange produced Audax regulations, which belonged to his Auto newspaper. Under the Audax regulations, riders rode as a group. Successful riders were awarded a certificate called a Brevet d'Audax. A group of successful audax cyclists formed the Audax Club Parisien (ACP), which took over the organisation of Audax events on Desgrange's behalf. In 1920, there was a disagreement between Desgrange and the ACP. Desgrange withdrew ACP's permission to organise events under his Audax regulations, and ACP created its own allure libre (free-paced) version of the sport, where successful riders were awarded certificates called Brevets des Randonneurs. This style is now popularly known as "randonneuring".
