Drafting (racing)
Drafting or slipstreaming is an aerodynamic technique where two vehicles or other moving objects are caused to align in a close group, reducing the overall effect of drag due to exploiting the lead object's slipstream. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure required to maintain a certain speed and can also slightly reduce the energy expenditure of the lead vehicle or object. Drafting in sport Drafting is used to reduce wind resistance and is seen most commonly in bicycle racing, motorcycle racing, car racing, and speedskating, though drafting is occasionally used even in cross-country skiing, downhill skateboarding, and running. Some forms of triathlon allow drafting. Drafting occurs in swimming as well: both in open-water races (occurring in natural bodies of water) and in traditional races in competition pools. In a competition pool a swimmer may hug the lane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Longboarding
Longboarding is typically defined as a variation of skateboarding that involves a larger board and softer urethane wheels. Longboards vary in shape and size. Compared to skateboards, longboards are more stable at speed and have more traction, due to larger wheel size and lower wheel durometers. A standard skateboard is typically between 28-34 inches long, whereas a longboard may exceed 50 inches. Many longboards use trucks that have different geometric parameters than skateboards. The skateboards use "traditional kingpin trucks" while longboards often use "reverse kingpin trucks." This hardware change is the key element in the increased stability that longboards offer. The term "longboarding" encapsulates multiple disciplines of riding. These include downhill, freeride, freestyle, dance and long-distance-push. Longboarding's disciplines vary significantly in terms of physical requirements, risk, and social demographic. While there are exceptions, there are distinct separate comm ...

IndyCar Series
The IndyCar Series, currently known as the NTT IndyCar Series under sponsorship, is the highest class of regional North American open-wheel single-seater formula racing cars in the United States, which has been conducted under the auspices of various sanctioning bodies since 1920 after two initial attempts in 1905 and 1916. The series is self-sanctioned by its parent company, INDYCAR, LLC., which began in 1996 as the Indy Racing League (IRL) and was created by then Indianapolis Motor Speedway owner Tony George as a competitor to Championship Auto Racing Teams (CART). In 2008, the IndyCar Series merged with CART's successor, the Champ Car World Series and the history and statistics of both series, as well as those from its predecessors, were unified. The series' premier event is the Indianapolis 500, which was first held in 1911. Overview Series name For 1996–1997, the series was simply referred to as the ''Indy Racing League.'' For 1998–1999, the series garnered its fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula One
Formula One (also known as Formula 1 or F1) is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The World Drivers' Championship, which became the FIA Formula One World Championship in 1981, has been one of the premier forms of racing around the world since its inaugural season in 1950. The word ''formula'' in the name refers to the set of rules to which all participants' cars must conform. A Formula One season consists of a series of races, known as ''Grands Prix'', which take place worldwide on both purpose-built circuits and closed public roads. A points system is used at Grands Prix to determine two annual World Championships: one for drivers, the other for constructors. Each driver must hold a valid Super Licence, the highest class of racing licence issued by the FIA. The races must run on tracks graded "1" (formerly "A"), the highest grade-rating issued ...

Open Wheel Racing
An open-wheel single-seater (often known as formula car) is a car with the wheels outside the car's main body, and usually having only one seat. Open-wheel cars contrast with street cars, sports cars, stock cars, and touring cars, which have their wheels below the body or inside fenders. Open-wheel cars are built both for road racing and oval track racing. Street-legal open-wheel cars, such as the Ariel Atom, are scarce as they are often impractical for everyday use. History American racecar driver and constructor Ray Harroun was an early pioneer of the concept of a lightweight single-seater, open-wheel "monoposto" racecar. After working as a mechanic in the automotive industry, Harroun began competitive professional racing in 1906, winning the AAA National Championship in 1910. He was then hired by the Marmon Motor Car Company as chief engineer, charged with building a racecar intended to race at the first Indianapolis 500, which he went on to win. He developed a revolutionar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wired Magazine
''Wired'' (stylized as ''WIRED'') is a monthly American magazine, published in print and online editions, that focuses on how emerging technologies affect culture, the economy, and politics. Owned by Condé Nast, it is headquartered in San Francisco, California, and has been in publication since March/April 1993. Several spin-offs have been launched, including ''Wired UK'', ''Wired Italia'', ''Wired Japan'', and ''Wired Germany''. From its beginning, the strongest influence on the magazine's editorial outlook came from founding editor and publisher Louis Rossetto. With founding creative director John Plunkett, Rossetto in 1991 assembled a 12-page prototype, nearly all of whose ideas were realized in the magazine's first several issues. In its earliest colophons, ''Wired'' credited Canadian media theorist Marshall McLuhan as its "patron saint". ''Wired'' went on to chronicle the evolution of digital technology and its impact on society. ''Wired'' quickly became recognized ...

Breaking2
Breaking2 was a project by Nike to break the two-hour barrier for the marathon. Nike announced the project in November 2016 and organized a team of three elite runners who trained for a private race. The event was held on the Formula One race track Autodromo Nazionale Monza in Italy on May 6, 2017. Eliud Kipchoge won the race with a time of 2:00:25. While the world record at the time was 2:02:57, this run was not recognized as a new record, because Kipchoge and the other two elite athletes ran with a roster of interchangeable pacemakers. Team members Nike chose three runners to make the attempt: At the time, Kipchoge was the defending Olympic champion, having won the marathon at the 2016 Summer Olympics in Rio de Janeiro, and Zersenay was the half marathon WR holder (58:23, set in 2010). Nike also brought in 30 of the world's best runners to serve as pacers for the race, including Andrew Bumbalough, Sam Chelanga, Chris Derrick, Bernard Lagat, and Lopez Lomong. Preparation ...

Pacemaker (running)
A pacemaker or pacesetter, sometimes informally called a rabbit, is a runner who leads a middle- or long-distance running event for the first section to ensure a fast time and avoid excessive tactical racing. Pacemakers are frequently employed by race organisers for world record attempts with specific instructions for lap times. Some athletes have essentially become professional pacemakers. A competitor who chooses the tactic of leading in order to win is called a front-runner rather than a pacemaker. Pacemakers may be used to avoid the tactics of deception that are possible in competition by those who, for example, race away from the start line (and are likely to subsequently slow down), giving the other runners the impression that they are far behind. A trusted team of pacemakers who are paid to keep the runners at a speed that they can manage for the rest of the race become useful in such a situation. Pacemakers are also used on world record attempts in order to make sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peloton
In a road bicycle race, the peloton (from French, originally meaning 'platoon') is the main group or pack of riders. Riders in a group save energy by riding close ( drafting or slipstreaming) to (particularly behind) other riders. The reduction in drag is dramatic; riding in the middle of a well-developed group, drag can be reduced to as little as 5%–10%. Exploitation of this potential energy saving leads to complex cooperative and competitive interactions between riders and teams in race tactics. The term is also used to refer to the community of professional cyclists in general. Definition More formally, a peloton is defined as "two or more cyclists riding in sufficiently close proximity to be located either in one of two basic positions: (1) behind cyclists in zones of reduced air pressure, referred to as ‘drafting’, or (2) in non-drafting positions where air pressure is highest. Cyclists in drafting zones expend less energy than in front positions." A peloton has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Bicycle Racing
Road bicycle racing is the cycle sport discipline of road cycling, held primarily on paved roads. Road racing is the most popular professional form of bicycle racing, in terms of numbers of competitors, events and spectators. The two most common competition formats are mass start events, where riders start simultaneously (though sometimes with a handicap) and race to a set finish point; and time trials, where individual riders or teams race a course alone against the clock. Stage races or "tours" take multiple days, and consist of several mass-start or time-trial stages ridden consecutively. Professional racing originated in Western Europe, centred in France, Spain, Italy and the Low Countries. Since the mid- 1980s, the sport has diversified, with races held at the professional, semi-professional and amateur levels, worldwide. The sport is governed by the Union Cycliste Internationale (UCI). As well as the UCI's annual World Championships for men and women, the biggest even ...
