Race track in the context of "Motorsports"

A relay race is a racing competition where members of a team take turns completing parts of racecourse or performing a certain action. Relay races take the form of professional races and amateur games. Relay races are common in running, orienteering, swimming, cross-country skiing, biathlon, or ice skating (usually with a baton in the fist). In the Olympic Games, there are several types of relay races that are part of track and field, each consisting of a set number of stages (legs) (usually four), each leg run by different members of a team. The runner finishing one leg is usually required to pass the next runner a stick-like object known as a "baton" while both are running in a marked exchange zone. In most relays, team members cover equal distances: Olympic events for both men and women are the 400-metre (4 × 100-metre) and 1,600-metre (4 × 400-metre) relays. Some non-Olympic relays are held at distances of 800 m, 3,200 m, and 6,000 m. In the less frequently run medley relays, however, the athletes cover different distances in a prescribed order—as in a sprint medley of 200, 200, 400, 800 metres or a distance medley of 1,200, 400, 800, 1,600 metres.

An all-weather running track is a rubberized, artificial running surface for track and field athletics. It provides a consistent surface for competitors to test their athletic ability unencumbered by adverse weather conditions. Historically, various forms of dirt, rocks, sand, and crushed cinders were used. Many examples of these varieties of track still exist worldwide.

A cinder track is a type of race track, generally purposed for track and field or horse racing, whose surface is composed of cinders. For running tracks, many cinder surfaces have been replaced by all-weather synthetic surfaces, which provide greater durability and more consistent results, and are less stressful on runners. The impact on performance as a result of differing track surfaces is a topic often raised when comparing athletes from different eras.

Synthetic tracks emerged in the late 1960s; the 1964 Olympics were the last to use a cinder track.

In physics, circular motion is movement of an object along the circumference of a circle or rotation along a circular arc. It can be uniform, with a constant rate of rotation and constant tangential speed, or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves the circular motion of its parts. The equations of motion describe the movement of the center of mass of a body, which remains at a constant distance from the axis of rotation. In circular motion, the distance between the body and a fixed point on its surface remains the same, i.e., the body is assumed rigid.

Examples of circular motion include: special satellite orbits around the Earth (circular orbits), a ceiling fan's blades rotating around a hub, a stone that is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, and a gear turning inside a mechanism.

Sports car racing is a form of motorsport road racing that uses sports cars with two seats and enclosed wheels. The cars in question may be either purpose-built sports prototypes, which are the highest level in sports car racing; or grand tourers (GT cars) which, being based on road-going models, are considerably more common, but not as fast. Sports car races are often endurance races run over particularly long distances or large amounts of time (generally between 6 and 24 hours), resulting in an emphasis on reliability and efficiency of the car and its drivers over outright car performance or driver skills. The FIA World Endurance Championship and IMSA SportsCar Championship are some of the best-known sports car racing series, and so is the GT World Challenge. Sports car racing is one of the main types of circuit auto racing, alongside open-wheel racing (such as Formula One and Indycar), touring car racing (such as BTCC and V8 Supercars, which is based on 'saloon cars' as opposed to the 'exotics' seen in sports cars) and stock car racing (such as NASCAR).

A hybrid of the purism of open-wheelers and the familiarity of touring car racing, sports car racing is commonly associated with the annual 24 Hours of Le Mans endurance race. First run in 1923, Le Mans is one of the longest-running motor races. Well-known defunct sports car races include the Italian classics, the Targa Florio (1906–1977) and Mille Miglia (1927–1957), and the Mexican Carrera Panamericana (1950–1954). Most top-class sports car races focus more on endurance and strategy than pure speed or skills, and longer races usually involve complex pit strategies and regular driver changes. As a result, sports car racing is seen more as a team endeavour than an individual sport, with team managers such as John Wyer, Tom Walkinshaw, driver-turned-constructor Henri Pescarolo, Peter Sauber and Reinhold Joest becoming almost as famous as some of their drivers.

Fuji Speedway (富士スピードウェイ, Fuji Supīdowei) is a motorsport race track standing in the foothills of Mount Fuji, in Oyama, Suntō District, Shizuoka Prefecture, Japan. It was built in the early 1960s. In the 1980s, Fuji Speedway was used for the FIA World Sportscar Championship and national racing. Originally managed by Mitsubishi Estate, Fuji Speedway was acquired by Toyota Motor in 2000. The circuit hosted the Formula One 2007 Japanese Grand Prix after an absence of nearly 30 years, replacing the Suzuka Circuit owned by Honda. After Fuji Speedway hosted the 2008 race, the Japanese Grand Prix returned to Suzuka for races from 2009 onward. The Super GT Fuji 500 km race is held at the racetrack on Golden Week.

Fuji Speedway has one of the longest straights in motorsport, at 1.475 km (0.917 mi) in length. The circuit has an FIA Grade 1 license at least until April 2026.

The Suzuka International Racing Course (Japanese: 鈴鹿国際レーシングコース, Hepburn: Suzuka Kokusai Rēsingu Kōsu), a.k.a. the Suzuka Circuit (鈴鹿サーキット, Suzuka Sākitto), is a 5.807 km (3.608 mi) long motorsport race track located in Ino, Suzuka City, Mie Prefecture, Japan and operated by Honda Mobilityland, a subsidiary of Honda Motor Co, Ltd. It has a capacity of 155,000. It is most well known for its use in the international Formula One and Japanese Super Formula championships.
