Bump Draft
Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure and can even slightly reduce the energy expenditure of the lead vehicle. 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 line that separates them from the swimmer they are abaft of thereby taking ...

Longboarding
Longboarding is a variation of skateboarding typified by the use of longer boards ("decks") with longer wheelbases and softer wheels. While longboards vary widely in shape and size, compared to street skateboards longboards are designed to be more stable at speed and to have more traction due to larger wheel sizes and softer wheel durometers. While standard street skateboards may typically be between 28 and 34 inches long, longboards can range anywhere from 32 to 50 inches in length. Ride characteristics of longboards generally differ from that of street skateboards due to the use of specialized longboard trucks that have different properties than those typically used with skateboards; while street skateboards use "traditional kingpin" (TKP) trucks that are optimized for tight turning radii, ollie and flip tricks, slides, grinds, and transition skating, longboards are typically paired with "reverse kingpin" (RKP) trucks that are designed for increased stability at higher speeds, ...

Wired (magazine)
''Wired'' is a bi-monthly American magazine that focuses on how emerging technologies affect culture, the economy, and politics.

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 di 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 their top sponsored athletes to serve as pacers for the race, including Andrew Bumbalough, Sam Chelanga, Chris Derrick, Bernard Lagat, and Lopez Lomong. ...

Pacemaker (running)
A pacemaker or pacesetter, sometimes informally called a rabbit, is a runner who leads a middle distance track event, middle- or long-distance running event for the first section to ensure a high speed and to avoid excessive tactical racing. Pacemakers are frequently employed by race organisers for list of world records in athletics, 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. P ...

Headwind
A tailwind is a wind that blows in the direction of travel of an object, while a headwind blows against the direction of travel. A tailwind increases the object's speed and reduces the time required to reach its destination, while a headwind has the opposite effect. The terms are also used metaphorically in business and elsewhere about circumstances where progress is made harder (headwind) or easier (tailwind). Travel In aeronautics, a headwind is favorable in takeoffs and landings because an airfoil moving into a headwind is capable of generating greater lift (force), lift than the same airfoil moving through tranquil air, or with a tailwind, at equal ground speed. As a result, aviators and air traffic controllers commonly choose to take off or land in the direction of a runway that will provide a headwind. Aircraft carriers usually turn into the wind during takeoffs and landings, and may increase their own speed. While on take-off and landing, headwinds are good because ...

Peloton
In a road Cycle sport, bicycle race, the peloton (, originally meaning ) is the main group or pack of riders. Riders in a group save energy by riding close (drafting (racing), drafting or slipstreaming) to (particularly behind) other riders. The reduction in drag (physics), drag is dramatic; riding in the middle of a well-developed group, drag can be reduced by as much as 95%. 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 ...

Road Bicycle Racing
Road bicycle racing is the cycle sport discipline of road cycling, held primarily on Road surface, 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 Handicapping, handicap) and race to a set finish point; and time trials, where individual time trial, individual riders or team time trial, 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 (UCI). As well as the UCI's annual UCI Road World Champio ...

Cycling
Cycling, also known as bicycling or biking, is the activity of riding a bicycle or other types of pedal-driven human-powered vehicles such as balance bikes, unicycles, tricycles, and quadricycles. Cycling is practised around the world for purposes including transport, recreation, exercise, and competitive sport. History Cycling became popularized in Europe and North America in the latter part and especially the last decade of the 19th century. Today, over 50 percent of the human population knows how to ride a bike. War The bicycle has been used as a method of reconnaissance as well as transporting soldiers and supplies to combat zones. In this it has taken over many of the functions of horses in warfare. In the Second Boer War, both sides used bicycles for scouting. In World War I, France, Germany, Australia and New Zealand used bicycles to move troops. In its 1937 invasion of China, Japan employed some 50,000 bicycle troops, and similar forces were instrumental in ...
