WBMX racing is a type of off-road bicycle racing. The format of BMX was derived from motocross racing. BMX bicycle races are sprint races on purpose-built off-road single-lap race tracks. The track usually consists of a starting gate for up to eight racers, a groomed, serpentine, dirt race course made of various jumps and rollers and a finish line. The course is usually flat, about 15 feet (4.6 m) wide and has large banked corners, which are angled inward, that help the riders maintain speed. The sport of BMX racing is facilitated by a number of regional and international sanctioning bodies. They provide rules for sanctioning the conduct of the flying, specify age group and skill-level classifications among the racers, and maintain some kind of points-accumulation system over the racing season. The sport is very family oriented and largely participant-driven, with riders ranging in age from 2 to 70, and over. Professional ranks exist for both men and women, where the age ranges from 18 to 40 years old.
WCycle speedway is a form of bicycle racing on short oval dirt tracks, usually outdoors, occasionally indoors, typically 70–90 metres long. Like motorcycle speedway, riders use machines without brakes or multiple gears but, unlike motor speedway, the object is not to slide bikes round the turns.
WCyclo-cross is a form of bicycle racing. Races typically take place in the autumn and winter, and consist of many laps of a short course featuring pavement, wooded trails, grass, steep hills and obstacles requiring the rider to quickly dismount, carry the bike while navigating the obstruction and remount. Races for senior categories are generally between 40 minutes and an hour long, with the distance varying depending on the ground conditions. The sport is strongest in the traditional road cycling countries such as Belgium, France and the Netherlands.
WDuathlon is an athletic event that consists of a running leg, followed by a cycling leg and then another running leg in a format similar to triathlons. The International Triathlon Union governs the sport internationally.
WMountain bike racing is the competitive cycle sport discipline of mountain biking held on off-road terrain. The Union Cycliste Internationale (UCI) recognised the discipline relatively late in 1990, when it sanctioned the world championships in Durango, Colorado. The first UCI Mountain Bike World Cup series took place in 1988. Its nine-race circuit covered two continents—Europe and North America—and was sponsored by Grundig. Cross-country racing was the only World Cup sport at this time. In 1993, a six-event downhill World Cup was introduced. In 1996, cross-country mountain biking events were added to the Olympic Games. In 2006, cross-country mountain biking events became part of the World Deaf Cycling Championships for the first time in San Francisco, USA.
WRoad bicycle racing is the cycle sport discipline of road cycling, held 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 and race to 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.
WTrack cycling is a bicycle racing sport usually held on specially built banked tracks or velodromes using track bicycles.
WA triathlon is an endurance multisport race consisting of swimming, cycling, and running over various distances. Triathletes compete for fastest overall completion time, racing each segment sequentially with the time transitioning between the disciplines included. The word is of Greek origin, from τρεῖς or treis (three) and ἆθλος or athlos (competition).
