50-534: The TT Circuit Assen is a motorsport race track built in 1955 and located in Assen , Netherlands. Host of the Dutch TT , it is popularly referred to as "The Cathedral of Speed" by motorcycle racing fans. The venue has the distinction of holding the most Grand Prix motorcycle races every year (except 2020 ) since the series was created in 1949 . It has a capacity of 110,000 spectators, including 60,000 seats . Since 1992,

100-403: A 'floating' manner to accommodate the extra space that was needed. The lay-out of the circuit was also slightly altered. The circuit was fundamentally redesigned again in 2006, becoming the so-called A-Style Assen TT Circuit. All alterations aside, only one section of the circuit is original; the finish line never moved. On 21 September 2009 it was announced that a new chicane will be added, after

150-433: A distance of eight miles. It was won by the locomotive of Isaac Watt Boulton , one of six he said he had run over the years, perhaps driven by his 22-year-old son, James W. The race was against Daniel Adamson's carriage, likely the one made for Mr. Schmidt and perhaps driven by Mr. Schmidt himself. The reports do not indicate who was driving, since both were violating the red-flag law then fully in force. Boulton's carriage

200-569: A high-speed test, car handling manoeuvres can be tested such as precision drifting , donuts, handbrake turns, reversing and so on. Other disciplines of automobile sport include: The international motorcycle sport governing body recognised by the International Olympic Committee is the Fédération Internationale de Motocyclisme (FIM). Disciplines include: The international powerboating governing body recognised by

250-584: A hill, at private and closed roadways where higher speeds and distances can be reached than at an autotesting course for example. Time attack are terms used by series that run sprints at racing circuits where competitors try to set the quickest lap time rather than racing head-to-head with others. Time trials are run by the Sports Car Club of America , amongst others. Rallysprints are mainly sanctioned and held in continental Europe. Ultimately, they are similar to other time trial sprints but originate from

300-611: A new media and medical centre. Between September 2001 and April 2002, another €9 million was spent on the enlargement of the paddock area from 40 to 60.000 square metres . This upgrade meant that the Veenslang and Ruskenhoek corners had to be altered. The main straight has also moved about 50 metres eastwards and a new two-lane tunnel now connects the paddock with the main entrance road and the media accreditation / welcome centre. The Mandeveen and Duikersloot corners have been moved back by 10 metres to accommodate larger run-offs and gravel beds at

350-449: A race is between competitors running head-to-head, in its International Sporting Code, the FIA defines racing as two or more cars competing on the same course simultaneously. Circuit racing takes place on sealed-surface courses at permanent autodromes or on temporary street circuits . Competitors race over a set number of laps of the circuit with the winner being the first to finish, or for

400-585: A request from the A1GP organization, however A1GP was unable to start the 2009–2010 season and as a substitute the Superleague Formula replaced A1GP. Assen race track was built in 1955, and initially had a length of 7.705 km (4.788 mi). The current track has a length of 4.555 km (2.830 mi) with the mixture of super fast flat-out and slow corners. The longest straight is 560 m (1,840 ft). The curves in Assen were traditionally banked and

450-460: A sealed surface such as asphalt or concrete. Notable off-road races on open terrain include the Baja 1000 desert race, organised by SCORE International . The FIA authorise Extreme E , an electric off-road series whose organisers have announced a hydrogen fuel series, Extreme H, to begin in 2025. Examples of off-road racing disciplines and series include: Drag racing is an acceleration contest from

500-488: A set length of time with the winner having completed the highest number of laps, with others classified subsequently. Circuit racing replaced point-to-point (city-to-city) racing early in the history of motorsport, for both spectator appeal and as safety concerns brought in regulation of the sport, forcing organisers to use closed, marshalled and policed circuits on closed public roads. Aspendale Racecourse in Australia in 1906

550-427: A short course and a longer course which uses part of the shorter one, usually the main straight, such as Brands Hatch . The Le Mans road race venue is centred on a smaller permanent circuit within its complex. Surfaces include: Race tracks are primarily designed for road racing competition through speed, featuring defined start-finish lines or posts, and sometimes even a series of defined timing points that divide

600-399: A standing start along a short and straight course. Vehicles of various types can compete, usually between two vehicles. Winners can be the first to finish of competing pairs or by setting the fastest time, and competitions may have heats and/or series of runs. Kart racing is a form of circuit racing using very small and low vehicles not considered as automobiles known as go-karts. It is one of

650-445: A whole new circuit was built by using a third of the original street circuit, joined with purpose-built sections, but less than a third of the length and much more like a modern road racing circuit. In the period of 1999–2002, the circuit invested millions in upgrades. In 1999, the circuit management placed a new main grandstand and hospitality buildings. In 2000, a new Race Control tower was built, as well as 34 newly equipped pit boxes,

700-558: Is Nardò where high-speed manufacturer testing often takes place, and the Indianapolis Motor Speedway . Some oval tracks are variations on an oval shape, for practical reasons or to introduce varying difficulties such as Talladega (a tri-oval). Most race tracks have meandering circuits with many curves, chicanes and changes in height, to allow for a challenge in skill to the competitors, notably motocross and touring car racing – these tend to predominate throughout most of

750-483: Is a facility built for racing of vehicles, athletes, or animals (e.g. horse racing or greyhound racing ). A race track also may feature grandstands or concourses. Race tracks are also used in the study of animal locomotion . A racetrack is a permanent facility or building. Racecourse is an alternate term for a horse racing track, found in countries such as the United Kingdom, India, Australia, Hong Kong, and

800-453: Is a form of motorsport where drivers intentionally lose rolling traction in corners through oversteering but maintain momentum with effective throttle control, clutch use and corrective steering. In competition a panel of judges award marks on artistry and car control through the corner or series of corners. Competitions often feature pairs of cars driving together where a lead car and a chase car go head-to-head, with only one car going through to

850-434: Is called a series, and a grouping of competitions often forms the basis of a championship , cup or trophy . Not all nations have a sporting authority affiliated with the FIA, some disciplines may not fall within the FIA's remit of control, or organisations may choose to ignore the claim of the authority of others. Examples include banger racing and stock car racing in the United Kingdom which are claimed by both

900-588: Is expected to be visited by 300,000 people, and the total investment is approximately €85 million. As of August 2024, the fastest official race lap records at the TT Circuit Assen are listed as: Motorsport Different manifestations of motorsport with their own objectives and specific rules are called disciplines. Examples include circuit racing , rallying and trials . Governing bodies, also called sanctioning bodies, often have general rules for each discipline, but allow supplementary rules to define

950-641: The International Olympic Committee is the Union Internationale Motonautique (UIM). The organisation's origins date back to 1922. The international air sports governing body recognised by the International Olympic Committee is the Fédération Aéronautique Internationale (FAI). The FAI also governs non-powered air sport such as gliding and ballooning, however its motorised sports include: Race track A race track ( racetrack , racing track or racing circuit )

1000-723: The Middle Ages , and records exist of a public racecourse being opened at Newmarket , in London, in 1174. In 1780, the Earl of Derby created a horse-racing course on his estate at Epsom; the English Derby continues to be held there today. Racecourses in the British Isles are based on grass, known as turf tracks. In the United States, the race tracks are soil. With the advent of the automobile in

1050-794: The Monaco and Singapore Grands Prix in Formula One . Some evidence remains of racetracks being developed in several ancient civilizations. The most developed ancient race tracks were the hippodromes of the Ancient Greeks and the circuses ( circi ) of the Roman Empire . Both of these structures were designed for horse and chariot racing. The stadium of the Circus Maximus in Ancient Rome could hold 200,000 spectators. Racing facilities existed during

SECTION 20

1100-692: The Monaco GP , and the Circuit de la Sarthe circuit in Le Mans , France. These are not permanent facilities built for racing (although parts of the Circuit de la Sarthe are purpose-built, and closed to the public). After World War II , many wartime airfields, particularly in Great Britain, were left without further use. This coincided with a post-war boom in motorsport, and many airfields were converted to race tracks, where

1150-618: The United States , dirt track racing became popular. After World War II , the Grand Prix circuit became more formally organised. In the United States, stock car racing and drag racing became firmly established. The Fédération Internationale de l'Automobile (FIA), formed in 1904, is the oldest and most prominent international governing body. It claims to be the sole international motor sporting authority for automobiles and other land vehicles with four or more wheels, whilst acknowledging

1200-458: The 1920s, many of the races on the AAA Championship circuit were run on such board tracks. Modern racetracks are designed with spectator safety being paramount, following incidents of spectator and track marshals fatalities. These often involve run-off areas, barriers, and high fencing. Racetracks are used for: Some racetracks offer little in the way of permanent infrastructure other than

1250-624: The ASNs must be obtained to organise events using their rules, and their licenses must be held by participants. Not all ASNs function in the same manner, some are private companies such as Motorsport UK, some are supported by the state such as France's FFSA, or in the case of the US's ACCUS, a council of sanctioning bodies is the national representative at FIA meetings. ASNs, their affiliated clubs or independent commercial promotors organise motorsport events which often include competitions . A collective of events

1300-618: The Oshkosh and the Green Bay (the machines were referred to by their town of origin). This is examined and illustrated in detail in The Great Race of 1878 by Richard Backus, Farm Collector, May/June 2004. In 1894, the French newspaper Le Petit Journal organised a contest for horseless carriages featuring a run from Paris to Rouen. This is widely accepted as the world's first motorsport event, and

1350-671: The Oval Racing Council and the National Stock car Association, despite the claim by the FIA affiliated ASN, Motorsport UK , to be the "governing body of all four-wheel motorsport in the UK". SCORE International , National Auto Sport Association and National Off-Road Racing Association of the United States are also not members of the FIA affiliation system but may work with members for international matters. Although English dictionaries do not unanimously agree and singularly define that

1400-607: The United Arab Emirates. Race tracks built for bicycles are known as velodromes . Circuit is a common alternate term for race track, given the circuit configuration of most race tracks, allowing races to occur over several laps. Some race tracks may also be known as speedways , or raceways . A race course , as opposed to a racecourse , is a nonpermanent track for sports, particularly road running , water sports , road racing , or rallying . Many sports usually held on race tracks also can occur on temporary tracks, such as

1450-412: The authority of the Fédération Internationale de Motocyclisme (FIM) over vehicles with one to three wheels, which FIM calls motorcycle sport. FIM and FIA are both recognised as international sports federations by the International Olympic Committee . Within the FIA's structure, each affiliated National Sporting Authority ( ASN ) is recognised as the sole authority in their nation. Permission of

1500-519: The cars and courses used in special stage rallying with the elements of navigation and itinerary removed, and not necessarily requiring a co-driver to call pacenotes . Rallying involves driving to a set itinerary, following a prescribed route and arriving and departing at control points at set times with penalties applied for diverging from the route or arriving late and early. Rallies nearly always involve routes on open roads, closed special stages are used on some rallies where competitors drive against

1550-516: The character of a particular competition, series or championship. Groups of these are often categorised informally, such as by vehicle type, surface type or propulsion method. Examples of categories within a discipline are formula racing , touring car racing , sports car racing , etc. The first prearranged match race of two self-powered road vehicles over a prescribed route occurred in the north west of England at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, Manchester ,

1600-551: The circuit has also been part of the World SBK calendar except for the 2020 season. The original Assen track was first used for the 1926 Dutch TT (Tourist Trophy) race, after the first 1925 event was held on country roads through the villages of Rolde , Borger , Schoonloo and Grolloo , and organized by the Motorclub Assen en Omstreken . The brick- and semi-paved track had a length of 28.57 km (17.75 mi). The winner

1650-686: The clock, the winner having the shortest, lowest average or total time. Hillclimbing events often include classes of competition for various categories and ages of vehicle and so may be incorporated into car shows or festivals of motoring such as the Goodwood Festival of Speed . Hill climb courses can be short at less than 1 mile, or several miles long such as the 12.42 mile Pikes Peak course in Colorado , USA. Sprints are governed by national FIA member ASNs in United Kingdom, Ireland and Australia, amongst other places. They are held on courses that do not climb

1700-509: The clock. The classification of these rallies are determined by summing the times set with the fastest crews being victorious, as found in the World Rally Championship . This method is often called rally racing or stage rallying informally, whilst rallies that do not include special stages are distinctly regularity rallies . Rallies that include routes that cover terrain off-road are also known as rally raid or cross-country rallies,

1750-439: The general form of time trials and sprints. Hillclimbing is the most widely known form of time-trial due to its status as the only time trial or sprint form to have international FIA championships and endorsement. Its origins begin near the start of motorsport, particularly with the trials held that tested the capabilities of early automobiles to tackle uphill gradients. Contestants complete an uphill course individually and against

1800-447: The general rule of participants completing a course individually with the intention of setting the shortest time or highest average speed. This form of motorsport can be recreational or when competitive, rules may vary slightly such as whether to include the total time of several runs, the best time set, or the average pace of multiple courses to classify competitors. Qualifying sessions for circuit races and special stages in rallying take

1850-612: The late 19th and early 20th centuries, race tracks were designed to suit the nature of powered machines. The earliest tracks were modified horse-racing courses. Racing automobiles in such facilities began in September 1896, at Narragansett Park in Cranston, Rhode Island . The Indianapolis Motor Speedway was opened in August 1909. Beginning in the early 1900s, motorcycle races were run on high, banked, wooden race tracks called board tracks . During

1900-562: The most famous example being the Dakar Rally . In the United States, the National Off-Road Racing Association (NORRA) was founded in 1967 along with the Baja 1000 . Since the 1990s, this race has been organised by SCORE International whilst NORRA's events have closer followed the FIA regulations and standards for cross country rallies, although the association has no affiliation to ACCUS , the US's FIA member. Drifting

1950-486: The next heat or winning the competition. Autocross has multiple general meanings based on country of use. Also known as Autocross in US and Canada and Autoslalom in Continental Europe, these similar disciplines are held in the United Kingdom, Ireland, Australia and New Zealand. They involve precise car control, usually but not always against the clock on very short and compact temporary courses. Rather than being

2000-426: The same track, or incorporating many tracks in one venue. Commonly, running tracks are incorporated within general use or soccer stadiums, either permanently visible or covered by stands or pitches. Many horse and motorsport tracks are configurable, allowing different routes or sections. Some venues contain smaller tracks inside larger ones, with access tunnels and bridges for spectators. Some racetracks incorporate

2050-463: The southern part of the circuit. That part of the track has also been resurfaced with new asphalt. In total, the circuit has been shortened from 6.049 km (3.759 mi) to 6.027 km (3.745 mi). The total cost of these upgrades was €23 million. In 2005, the grandstand at the Geert Timmer corner was slightly altered. In order to improve the gravel run-off length, the grandstand was made in

2100-527: The sports regulated by FIA (under the name of CIK), permitting licensed competition racing for anyone from the age of 8 onward. It is generally accepted as the most economical form of motorsport available on four wheels. As a free-time activity, it can be performed by almost anybody, and as karting circuits can be indoors and not take as much space as other forms of motorsport, it can be accessible to retail consumers without much qualification or training. Non-racing speed competitions have various names but all carry

2150-412: The surface is extremely grippy, so the riders were able to drive much faster on the course than other circuits. Today these sloped or curved bends have been modified due to safety issues. On 6 July 2004, the organisation announced plans for an amusement park located to the north of the track. In 2006 the northern loop was removed and the length was shortened to 4.555 km (2.830 mi). The new centre

2200-574: The track into time sectors. A racetrack for cars (i.e. a car track) is a closed circuit, instead of a street circuit utilizing temporarily closed public roads . Race tracks can host individual or team sports. Racetracks can feature rolling starts , or fixed starts, with associated equipment (starting blocks, cages, wheel traps etc.) They invariably feature a pit lane , and usually timing equipment. Some car tracks are of an oval shape, and can be banked, which allows almost universal spectator views or high speed racing (cycling, stock cars). A famous one

2250-501: The track; others incorporate spectator facilities such as grandstands , hospitality or facilities for competitors, such as pit lanes and garages, paddocks and stables. Several racetracks are incorporated into larger venues or complexes, incorporating golf courses, museums, hotels, and conference centres. Some racetracks are small enough to be contained indoors, for sports such as motocross , track cycling , and athletics . Many racetracks are multi-use, allowing different types of sport on

2300-688: The world, but especially in Europe. Flatter meandering motorsport courses are sometimes called 'road circuits', originating in the fact that the earliest road racing circuits were simply closed-off public roads. Some car racetracks are specifically configured in a long straight, namely drag racing . True road circuits are still in use, e.g. the Australian GP has been run in Adelaide and continues to be in Melbourne on regular city streets. The most famous of these are

2350-644: Was Piet van Wijngaarden on a 500 cc Norton with an average speed of 91.4 km/h (56.8 mph). From 1926 on the Dutch TT was held at Assen on a street circuit through De Haar , Barteldsbocht, Oude Tol, Hooghalen , Laaghalen and Laaghalerveen . In 1951 the Italian Umberto Masetti took the record on a 500 cc Gilera with an average speed of 162.35 km/h (100.88 mph). In 1954, Geoff Duke of Great Britain reached 170.69 km/h (106.06 mph). The circuit remained unchanged until 1955, when

2400-651: Was developed from a scrapped John Bridge Adams light-rail vehicle. These were solid fired steam carriages. This event and the details of the vehicles are recorded in the contemporary press, The Engineer , and in Fletcher's books. The Wisconsin legislature passed an act in 1875 offering a substantial purse for the first US motor race, which was run on July 16, 1878, over a 200-mile course from Green Bay to Appleton, Oshkosh, Waupon, Watertown, Fort Atkinson and Janesville, then turning north and ending in Madison. Only two actually competed:

2450-483: Was the first purpose-built motor racing track in the world. After which, permanent autodromes popularly replaced circuits on public roads. In North America, the term road racing is used to describe racing and courses that have origins in racing on public highways; distinguished from oval racing , which has origins at purpose-built speedways using concrete or wooden boards . Off-road racing can take place on open terrain with no set path, or on circuits that do not have

2500-628: Was the first to involve what would become known as automobiles. On 28 November 1895, the Chicago Times-Herald race , running from Chicago to Evanston and back, a distance of sixty miles, was held. This is believed to be the first motorsport event in the United States of America. In 1900, the Gordon Bennett Cup was established. Motorsport was a demonstration event at the 1900 Summer Olympics . Following World War I , European countries organised Grand Prix races over closed courses. In
