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 event is the Tour de France, a three-week race that can attract over 500,000 roadside supporters a day.

Historically, the most competitive and devoted countries since the beginning of 20th century were Belgium, France and Italy, then road cycling spread in Colombia, Denmark, Germany, Luxembourg, the Netherlands, Portugal, Spain and Switzerland after World War II. However, as the sport grows in popularity through globalization, countries such as Kazakhstan, Australia, Russia, Slovakia, South Africa, Ecuador, New Zealand, Norway, the United Kingdom, Ireland, Poland and the United States continue to produce world-class cyclists.[5]

The first women's road championships were held in France in 1951. A women's road race discipline was added to the UCI Road World Championships at the 31st edition of the World Championships in 1958 in Reims.

Individual time trial (ITT) is an event in which cyclists race alone against the clock on flat or rolling terrain, or up a mountain road. A team time trial (TTT), including two-man team time trial, is a road-based bicycle race in which teams of cyclists race against the clock. In both team and individual time trials, the cyclists start the race at different times so that each start is fair and equal. Unlike individual time trials where competitors are not permitted to 'draft' (ride in the slipstream) behind each other, in team time trials, riders in each team employ this as their main tactic, each member taking a turn at the front while teammates 'sit in' behind. Race distances vary from a few km (typically a prologue, an individual time trial of usually less than 5 miles (8.0 km) before a stage race, used to determine which rider wears the leader's jersey on the first stage) to between approximately 20 miles (32 km) and 60 miles (97 km).

Stage races consist of several races, or stages, ridden consecutively. The competitor with the lowest cumulative time to complete all stages is declared the overall, or general classification (GC), winner. Stage races may also have other classifications and awards, such as individual stage winners, the points classification winner, and the "King of the Mountains" (or mountains classification) winner. A stage race can also be a series of road races and individual time trials (some events include team time trials). The stage winner is the first person to cross the finish line that day or the time trial rider (or team) with the lowest time on the course. The overall winner of a stage race is the rider who takes the lowest aggregate time to complete all stages (accordingly, a rider does not have to win all or any of the individual stages to win overall). Three-week stage races are called Grand Tours. The professional road bicycle racing calendar includes three Grand Tours - the Giro d'Italia, the Tour de France, and the Vuelta a Espana.[8]

The most commonly used bicycle in road races are simply known as racing bicycles. Their design is strictly regulated by the UCI, the sport's governing body. Specialist time trial bicycles are used for time trial events.

Clothing worn for road racing is designed to improve aerodynamics and improve rider comfort. The rider's shorts contain padding to improve comfort, and materials are chosen to manage rider temperature, manage sweat, and keep the rider as warm and dry as feasible in wet conditions. Cycling jerseys were originally made of wool; modern jerseys are made of synthetic fabrics such as lycra.

Wind conditions can also make otherwise routine sections of a course potentially selective. Crosswinds, particularly, alter the position of the "shadow" when drafting a rider, usually placing it diagonally behind the lead rider, forming a line of riders called an echelon.[15] To take advantage of this, an attacking rider rides at high speed at the front of the peloton, on the opposite side of the road from which the crosswind is blowing. Following riders are unable to fully shelter from the wind. If such tactics are maintained for long enough, a weaker rider somewhere in the line will be unable to keep contact with the rider directly ahead, causing the peloton to split up.[16]

In more organized races, a SAG wagon ("support and gear") or broom wagon follows the race to pick up stragglers. In professional stage racing riders who are not in a position to win the race or assist a teammate, will usually attempt to ride to the finish within a specified percentage of the winner's finishing time, to be permitted to start the next day's stage. Often, riders in this situation band together to minimize the effort required to finish within the time limit; this group of riders is known as the gruppetto or autobus. In one-day racing, professionals who no longer have any chance to affect the race outcome will routinely withdraw, even if they are uninjured and capable of riding to the finish.

One example of team tactics involves placing a strong domestique in a breakaway (rather than the designated team leader). If the domestique is a good chance to win if the breakaway is not brought back, it places the onus on other teams with favoured riders to expend energy chasing the breakaway, impeding their efforts to assist their leader in the final stages of the race. For instance, in the 2012 London Olympics men's road race the outright favourite was sprinter Mark Cavendish riding for the team of Great Britain. Another favoured rider was Matthew Goss riding for the Australian team. By placing Stuart O'Grady in the breakaway, the Australian team was able to force the British team to take primary responsibility for the chase and absolve themselves of the responsibility.[18]

In professional races, team coordination is often performed by radio communication between the riders and the team director, who travels in a team car behind the race and monitors the overall situation. The influence of radios on race tactics is a topic of discussion amongst the cycling community, with some arguing that the introduction of radios in the 1990s has devalued the tactical knowledge of individual riders and has led to less exciting racing.[19] In September 2009, the Union Cycliste Internationale (UCI), the governing body of pro cycling, voted to phase in a ban on the use of team radios in men's elite road racing.[20] However, after protests from teams, the ban introduced in 2011 excluded races on the top-level men's and women's circuits (the UCI World Tour and UCI Women's Road World Cup) and in 2015 the UCI reversed its stance, allowing race radios to be used in class HC and class 1 events from the 2016 season.[21]

Within the discipline of road racing, from young age different cyclists have different (relative) strengths and weaknesses.[22] Depending on these, riders tend to prefer different events over particular courses, and perform different tactical roles within a team.

The general leader does not generally react to breakaways by riders who trail substantially in cumulative time. Such escapes usually achieve other goals, such as winning the stage, collecting sprinting or mountain points, or just creating air time for their team sponsors as a dedicated camera bike typically accompanies the escape.

Cycling has been a discipline in the summer Olympics ever since the birth of the modern Olympic movement. Cycling activist, co-organizer of Peace Race, Wodzimierz Gobiewski said: "Cycling has become a major event on the Olympic programme ... Like many other sports it has undergone several changes over the years. Just as there used to be track and field events such as the standing high jump or throwing the javelin with both hands, cyclists, too, used to compete for medals in events which today have been forgotten; for example in Athens in 1896, they attempted a 12-hour race, and in London, in 1908, one of the events was a sprint for 603.49 metres (659.98 yards)."[24] The Olympic Games has never been as important in road cycling as in other sports. Until the distinction ended, the best riders were professionals rather than amateurs and so did not take part.[24] Law enforcement always escort the athletes to ensure they are kept safe during the cycling events, especially the road races.

The success of the races in the Parc de St-Cloud inspired the Compagnie Parisienne and the magazine Le Vlocipde Illustr to run a race from the Arc de Triomphe in Paris to the cathedral in Rouen on 7 November 1869. It was the world's first long-distance road race and also won by Moore, who took 10 hours and 25 minutes to cover 134 km. The runners-up were the Count Andr Castra, who had come second to Moore at St-Cloud, and Jean Bobillier, riding a farm bike that weighed 35 kg. The only woman to finish within 24 hours was the self-styled Miss America, in reality an unknown English woman who, like several in the field, had preferred not to compete under her real name.

The growth of organised cycle racing led to the development of national administrative bodies, in Great Britain in 1878, France 1881, the Netherlands 1883, Germany 1884 and Sweden 1900. Sometimes, as in Great Britain, cycling was originally administered as part of athletics, since cyclists often used the tracks used by runners. This, according to historian James McGurn, led to disputes within countries and internationally. e24fc04721
