Rallying
Rallying is also unique in its choice of where and when to race. Rallies take place on all surfaces and in all conditions: asphalt (tarmac), gravel, or snow and ice, sometimes more than one in a single rally, depending on the course and event. Rallies are also run every month of the year, in every climate from bitter cold to monsoonal rain. As a result of the drivers not knowing exactly what lies ahead, the lower traction available on dirt roads, and the driving characteristics of small cars, the drivers are much less visibly smooth than circuit racers, regularly sending the car literally flying over bumps, and sliding the cars out of corners.
A typical rally course consists of a sequence of relatively short (up to about ), timed "special stages" where the actual competition takes place, and untimed "transport stages" where the rally cars must be driven under their own power to the next competitive stage within a generous time limit. Rally cars are thus unlike virtually any other top-line racing cars in that they retain the ability to run at normal driving speeds, and indeed are registered for street travel. Some events contain "super special stages" where two competing cars set off on two parallel tracks (often small enough to fit in a football stadium), giving the illusion they are circuit racing head to head. Run over a day, a weekend, or more, the winner of the event has the lowest combined special and super special stage times. Given the short distances of super special stages compared to the regular special stages and consequent near-identical times for the frontrunning cars, it is very rare for these spectator-oriented stages to decide rally results, though it is a well-known axiom that a team cannot win the rally at the super special, but they can certainly lose it.
Rallying
In Britain, the legal maximum speed of 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 at average speeds of up to the legal limit of , and tackle six hillclimb or speed tests. On rest days and at lunch halts, the cars were shown to the public in exhibition halls. 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 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.
