In Britain, the legal maximum speed of 12 mph (19 km/h) precluded road racing, but in April and May 1900, the Automobile Club of Great Britain (the forerunner of the Royal Automobile Club) organised the Thousand Mile Trial, a 15-day event linking Britain's major cities, in order to promote this novel form of transport. Seventy vehicles took part, the majority of them trade entries. They had to complete thirteen stages of route varying in length from 43 to 123 miles (69 to 198 km) at average speeds of up to the legal limit of 12 mph (19 km/h), and tackle six hillclimb or speed tests. On rest days and at lunch halts, the cars were shown to the public in exhibition halls.[unreliable source?] This was followed in 1901 by a five-day trial based in Glasgow The Scottish Automobile Club organised an annual Glasgow–London non-stop trial from 1902 to 1904, then the Scottish Reliability Trial from 1905. The Motor Cycling Club allowed cars to enter its trials and runs from 1904 (London–Edinburgh, London–Land's End, London–Exeter—all still in being as mud-plugging classic trials). In 1908 the Royal Automobile Club held its 2,000 mi (3,200 km) International Touring Car Trial, and 1914 the important Light Car Trial for manufacturers of cars up to 1400 cc, to test comparative performances and improve the breed. In 1924, the exercise was repeated as the Small Car Trials.
The 1974 London-Sahara-Munich World Cup Rally followed four years later. The rally travelled southwards into Africa but a navigational error saw most of the rally become lost in Algerian desert. Eventually only seven teams reached the southernmost point of the rally in Nigeria with five teams making it back to West Germany having driven all legs and only the winning team completing the full distance. This, coupled with the economic climate of the 1970s the heat went out of intercontinental rallying after a second London–Sydney Marathon in 1977. The concept though was revived in 1979 for the original Paris-Dakar Rally. The success of the Dakar would eventually see intercontinental rallying recognised as its own discipline; the Rally Raid.
"bring together," c.1600, from French rallier, from Old French ralier "reassemble, unite again," from re- "again" (see re-) + alier "unite" (see ally (v.)). Intransitive meaning "pull together hastily, recover order, revive, rouse" is from 1660s. Related: Rallied; rallying. Rally round the flag (1862) is a line from popular American Civil War song "Battle Cry of Freedom."
