48-527: Gérard David (born 9 December 1944) is a Belgian racing cyclist . He rode in the 1970 Tour de France . This biographical article related to a Belgian cyclist born in the 1940s is a stub . You can help Misplaced Pages by expanding it . Bicycle racing Bicycle racing is recognised as an Olympic sport . Bicycle races are popular all over the world, especially in Europe. The countries most devoted to bicycle racing include Belgium, Denmark, France, Germany, Italy,

96-455: A lower bottom bracket than road racing bicycles; this is favorable since the lower seat height makes for easier remounting, and a lower center of gravity increases stability. Many cyclo-cross bicycles are now set up with a single chainring and chain "drop" guards. A single chainring setup simplifies mechanics and reduces the chance of the chain derailing on a bumpy course. People who do run a double chain-ring set up on their bicycles generally use

144-420: A 36–46 gearing. Many professional-level cyclo-cross bikes are set up with deep-section carbon tubular wheels, not for the purpose of aerodynamics, but to keep the wheel from being entrapped in deep sand or mud sections. Tubular tires are used to avoid pinch flats, decrease rolling resistance and increase grip with lower tire pressures. In addition, single speed cyclo-cross bikes are becoming increasingly popular for

192-524: A barrier is 40 cm. Since outside assistance is allowed, pits are included to provide a consistent area for this to occur. A pit to the right of the course is normal since most riders dismount to their left. In larger events a separate pit lane is featured so only those wishing a new bike or other assistance need enter the lane (this type was debuted at the Zeddam, Netherlands World Cup of January 1999). In some cases pits are provided in two different parts of

240-468: A contestant event in every Summer Olympic Games . Road bicycle racing involve both team and individual competition, and races are contested in various ways. They range from the one-day road race, criterium , and time trial to multi-stage events like the Tour de France and its sister events which make up cycling's Grand Tours . The races typically take place from spring through to autumn. Many riders from

288-513: A dirt course of jumps and banked and flat corners. Cycle speedway is bicycle racing on short outdoor dirt tracks, 70–90 m (230–300 ft) in length. Motor-paced racing and keirin use motorcycles for pacing, so cyclists achieve higher speeds. Gravel racing is one of the newest disciplines of bicycle racing, emerging in the 21st century. For example, one of the premiere gravel races, Unbound Gravel , started in 2006. Some precursors to gravel racing in its current form include road races like

336-463: A fixed gear bicycle with no brakes or freewheel. The ball is controlled by the bike and the head, except when defending the goal. Cycle Polo is a team sports sport that combines elements of traditional horse polo with bicycling and is played on grass. Cycle Polo's was included in the 1908 London Olympics as a demonstration sport. The game has become particularly popular in India. Hardcourt Bike Polo

384-430: A line with the lead cyclist pedaling harder while reducing the wind resistance for other riders, is of much less importance than in road racing where average speeds are much higher than in cyclo-cross. A cyclo-cross rider is allowed to change bicycles and receive mechanical assistance during a race. While the rider is on the course on one bike, their pit crew can clean, repair and oil a spare. There are many stories about

432-569: A sport extending beyond the boundaries of France when in 1924 the first international race, Le Critérium International de Cross-Country Cyclo-Pédestre, was held in Paris. Like many international cycle sports , cyclo-cross is administered by the Union Cycliste Internationale ; although it was not until the 1940s, around 40 years after cyclo-cross' inception, that the UCI began its regulation and

480-493: A sport for road racers during the off season, to vary their training during the cold months. Races typically take place in the autumn and winter (the international or World Cup season is September–January) and consist of many laps of a 2–3 km (1–2 mi) course featuring pavement, wooded trails, grass, steep hills, and obstacles requiring the rider to dismount, carry the bike and remount in one motion. Races for senior categories are generally between 30 minutes and an hour long,

528-419: A variety of reasons, including lower initial cost of setup, ease of use and maintenance, and decreased likelihood of mechanical failure on the course. Clothing is similar to that of road racing. However, since cyclo-cross is a cold-weather sport there is an emphasis toward warmer clothing such as long sleeves, tights, knickers and arm and leg warmers. While many racers will use standard two-piece road kits, there

576-774: Is LOTOJA which covers the 206 mi (332 km) from Logan, Utah , to Jackson, Wyoming . Criteriums are races based on circuits typically less than a mile in length and sometimes run for a set time (60 min, 90 min, etc.) rather than a specific distance. Criteriums are the most popular form of road racing in North America. In Belgium, kermesses are popular, single-day events of usually over 120 km (70 mi). As well as road races in which all riders start simultaneously, individual time trial and team time trial events are also held on road-based courses. Track cycling has been around since as early as 1870. The riders competed on wooden indoor tracks that closely resembled

624-488: Is a more popular, fast-paced, and physically demanding variation of Cycle Polo played on hard surfaces such as asphalt or concrete. In teams of three, players maneuver their bicycles while using mallets to strike a ball into the opposing team's goal. Originating in Seattle in the late 1990s, hardcourt bike polo has since gained a sharp spike in popularity worldwide, with organized leagues and tournaments held in urban centers across

672-434: Is a very strong preference to wear one piece skinsuits to maximize freedom of movement. The other advantage of skinsuits is that they are tighter, preventing the jersey from getting caught on stray tree branches during some singletrack sections of the race course. The one piece construction of the skinsuit also prevents it from exposing the torso while the rider shoulders the bike. Mountain bike shoes are adopted, as they allow

720-641: Is credited as having inspired the first cyclo-cross races and organized the first French National Championship in 1902. Géo Lefèvre , the originator of the idea for the Tour de France , also played a key role in the early days of the sport. After Octave Lapize attributed his win in the 1910 Tour de France to his off season training in cyclo-cross the sport began to spread to countries bordering France. Belgium organized its first national championship in 1910, Switzerland did so in 1912, then Luxembourg in 1923, Spain in 1929 and Italy in 1930. Cyclo-cross proved itself as

768-674: Is now on display at the museum in Ely , Cambridgeshire , England. The Union Cycliste Internationale was founded on 14 April 1900 by Belgium, the United States, France, Italy, and Switzerland to replace the International Cycling Association , which had been formed in 1892, over a row with Great Britain as well as because of other issues. Since the rise of the Olympic Movement at the 1896 Summer Olympics , cycling has been

816-491: Is similar to motorcycle trials . Points are awarded for bike handling skills. The first UCI Trials World Championships took place in 1986. Freestyle BMX is an extreme sport of stunt riding BMX bikes . Artistic cycling is a discipline where athletes perform tricks (called exercises) in a format similar to ballet or gymnastics. Cycle ball , also known as "radball" (from German), is a sport similar to association football played on bicycles. The two people on each team ride

864-461: Is smoother. Less emphasis is put on negotiating rough or even rocky ground with more stress on increased speed and negotiating different types of technical challenges. Drafting is of far less strategic importance than in road racing, though it can still be employed in paved sections or extremely windy conditions. Instead, tactics are chiefly focused on line choice, pacing strategy, passing technique, and racers' ability to identify and exploit sections of

912-697: The Tour of the Battenkill and Boulder–Roubaix (named after Paris–Roubaix ) which are road races with gravel sections. The distinguishing features of gravel racing include long distances, often 100 to 200 mi (160 to 320 km), and mass starts that include all categories of racers, similar to Gran Fondo rides. The bicycles and courses in gravel racing vary widely, from road bicycles with wide tires used on smooth gravel roads to bicycles that are similar to mountain bike used on courses that include technical trails. Speeds achieved on indoor tracks are usually greater than those on roads. Other factors affecting speed are

960-439: The 120 km (70 mi) Cootamundra Annual Classic it is 11.8 metres per second (42 km/h; 26 mph). In the 259 km (200 mi) 2010 Paris–Roubaix , Fabian Cancellara set a speed of 10.9 metres per second (39 km/h; 24 mph), while over the 818 km (500 mi) Furnace Creek 508 , the speed drops dramatically to 8.3 metres per second (30 km/h; 19 mph). For an extreme road distance such as

1008-521: The 4,800 km (3,000 mi) Race Across America , the average speed of the record holder is 5.7 metres per second (21 km/h; 13 mph), while the 2,350 km (1,000 mi) Freedom Trail over mountainous terrain in South Africa is at a record speed of 1.9 metres per second (6.8 km/h; 4.3 mph). Mountain bike trials is a sport where riders navigate natural and human-made obstacles without putting down their foot, or "dabbing". It

1056-548: The Netherlands, Spain and Switzerland. Other countries with international standing include Australia, Luxembourg, Slovenia, United Kingdom, United States and Colombia. The first bicycle race is popularly held to have been a 1,200 m (3,900 ft) race on the 31 May 1868 at the Parc de Saint-Cloud , Paris , France. It was won by expatriate Englishman James Moore who rode a wooden bicycle with solid rubber tires . The machine

1104-565: The Northern Hemisphere spend the winter in countries such as Australia to compete or train. Professional races range from the three-week "Grand Tour" stage races such as the Tour de France , Giro d'Italia and the Vuelta a España to multi-day stage races such as the Tour de Suisse and Tour of California , to single day "Classics" such as the Tour of Flanders and Milan–San Remo . The longest one-day road race sanctioned by USA Cycling

1152-463: The US and Great Britain. A variety of terrain is typical, ranging from roads to paths with short steep climbs, off camber sections, many corners and, a defining feature, sections where the rider may need, or would be best advised to dismount and run while carrying the bike. Under-tire conditions include asphalt, hardpack dirt, grass, mud and sand. In comparison to cross-country mountain bike events, terrain

1200-472: The United States. The Surf City race series held in Santa Cruz , CA has contributed to the history of cyclo-cross in the United States. The sport has experienced a growth in popularity in the United States since the mid-1990s. Cyclo-cross races are now regularly held in the fall and winter seasons throughout the United States and continue to grow in popularity. Cyclocross is typically an autumn and winter sport,

1248-764: The best cyclo-cross riders cross train in other cycling disciplines; however, cyclo-cross has reached such size and popularity that some racers are specialists, and many prioritize cyclo-cross races over other disciplines. Cyclo-cross bicycles are similar to road racing bicycles : lightweight, with somewhat narrow tires and drop handlebars. They are typically differentiated by their greater tire clearances, lower gearing, stronger frames, cantilever brakes or disc brakes and more upright riding position. They also share characteristics with mountain bikes in that they use knobby tread tires for traction and disc brakes. They have to be lightweight because competitors need to carry their bicycle to overcome barriers or slopes too steep to climb in

1296-403: The bicycle. Therefore the ability to fluidly dismount at speed, pick up and carry the bike, then put it back down and remount without losing momentum is key, and a faulty or slow dismount/remount may cost valuable seconds, waste energy or cause the competitor to crash. Often, when sections are extremely technical or become impossible to ride due to erosion from repeated wear or inclement weather,

1344-545: The bike onto the shoulder as soon as the rider's feet touch the ground. As a high-end bicycle purpose-built for a specific sport competition, they also differ from ordinary "hybrid or trekking" cross bikes , which are general-purpose utility bikes fitted with slightly wider 700C tires for use on unpaved paths or trails. Cyclo-cross bike design and frame geometry has evolved over the years. The first cyclo-cross bikes were touring-type road bikes, used for their cantilever bosses, slacker angles and wider tire clearance. Over time as

1392-485: The competitors to run, unlike their road racing counterparts, and due to their degree of traction (compared to smooth bottoms found on road racing shoes). Toe spikes are used to aid in running up steep muddy slopes and in the adverse underfoot conditions. Full-finger gloves are optional but generally recommended for hand protection and for grip in muddy/wet situations. Experienced riders racing in dry conditions may eschew gloves, presumably for better tractional feedback though

1440-510: The course that are conducive to attacking or recovery. Each section of the course typically lasts no longer than a handful of seconds. For example, long climbs are avoided in favour of short, sharp inclines. Sections are generally linked together, or long straights broken up, with tight corners. This not only allows a standard length course to fit in a relatively small area, but also forces competitors to constantly change speed and effort. Accelerating out of corners, then having to decelerate for

1488-534: The course, depending on the location, both of which require rider experience and technique. Some course sections may be extremely muddy, wet or snowy, and others are dusty and sandy. Most of these conditions are usually considered too extreme to be ridden with the standard 32c tire, and so much of the challenge of cyclo-cross lies in maintaining traction through loose or slippery terrain at speed. Also common are steps, barriers, ditches, stairs, steep slopes and very deep mud or sand which all require running while carrying

1536-573: The course. Long-format races, in which riders compete cross country also exist. Examples include the Three Peaks Cyclo-Cross , a 61 km race, Barry-Roubaix , and the American UltraCX Championship Series which consists of seven stages ranging from 80 to 115 km. Cyclo-cross courses require specific technical abilities of competitors. For example, dirt single-track and streams are also sometimes integrated into

1584-536: The distance varying depending on the conditions. The sport is strongest in traditional road cycling countries such as Belgium (Flanders in particular) and France. Mountain bike races are held off-road and involve moderate to high degree of technical riding. There are several varieties; the main categories are cross-country , enduro and downhill but also 4X or four-cross racing. BMX takes place off-road. BMX races are sprints on purpose-built off-road single-lap tracks, typically on single-gear bicycles. Riders navigate

1632-698: The first world championship was held in Paris in 1950. The first United States Cyclo-cross National Championships took place on 20 October 1963, in Palos Park, IL , near Chicago . These championships in the midwest continued until 1969. Cyclo-cross began to become popular in the United States in the 1970s, in New England and California. The Cyclo-cross National Championships restarted in 1975 in Berkeley , CA and have continued to be held every year at various locations throughout

1680-405: The globe. Cyclo-cross Cyclo-cross ( cyclocross , CX , cyclo-X or ' cross ) is a form of bicycle racing . Races typically take place in the autumn and winter (the international or "World Cup" season is October–February), and consist of many laps of a short (2.5–3.5 km or 1.5–2 mile) course featuring pavement, wooded trails, grass, steep hills and obstacles requiring

1728-565: The handlebar, and more natural bike portage. Races usually consist of many laps over a short course, ending when a time limit is reached, rather than after a specific number of laps or certain distance; the typical length for senior events is one hour, with 30 and 45 minute races for lower categories being the norm. Generally each lap is around 2.5–3.5 km and is 90% rideable. Races run under UCI rules must have courses that are always at least 3 m wide to encourage passing at any opportunity, but sections of singletrack are common for small races in

1776-402: The middle of the international season, i.e. they compete in the same category that they would be in for the following road season. Cyclo-cross bicycles generally resemble road racing bicycles . Cyclo-cross-specific frames differ with their wider tire clearances, knobby tires, cantilever or disc brakes, and lower gearing. Cables are generally routed on the upper side of the top tube, which allows

1824-471: The modern velodromes of today. Unlike road racing, which is dependent on environmental factors, indoor tracks ensure the sport can be competed all year round. It encompasses races that take place on banked tracks or velodromes . Events are quite diverse and can range from individual and team pursuits , two-man sprints, to various group and mass start races. Competitors use track bicycles which do not have brakes or freewheels. Cyclo-cross originated as

1872-548: The next before accelerating again is a common theme. Obstacles that force a rider to dismount and run with their bike or to " bunny hop " include banks too steep to ride up, steps, sand pits and plank barriers. Besides the start/finish area, these obstacles may be placed anywhere on the course that the race director desires. Several race directors have tried to limit bunny hopping for safety reasons by placing barriers in pairs or in triple (although under UCI rule no more than two barriers can appear in succession). The maximum height for

1920-670: The northern hemisphere season running from September to February. The World Championships take place in late January. The Canada championships are held in November with the US and UK championships held in January. In the United States, there is little racing after that except in states with year-round warm climates such as Florida and California. The cyclocross racing season within southern hemisphere nations typically runs from May to August. Riders' age categories for cyclocross under UCI rules are currently determined by their age on 1 January which lies in

1968-437: The origins of cyclo-cross. One is that European road racers in the early 1900s would race each other to the next town over from them and that they were allowed to cut through farmers' fields or over fences, or take any other shortcuts, in order to make it to the next town first. This was sometimes called steeple chase as the only visible landmark in the next town was often the steeple. This was a way for them to stay in shape during

2016-431: The racer will carry the bike and jog for an extended time to save energy. A more recent development to overcome obstacles such as barriers and sometimes ditches is the bunnyhop , a technique which came to prominence in 1989 when Danny De Bie used it in his successful World Championship run. Bunny hopping has become less popular as a result of race directors seeking to prevent its use by setting up two or three barriers in

2064-400: The rider to carry the bike comfortably on the right shoulder through portage sections, and prevents cable contamination by dirt. Popular on many cyclocross bikes is routing the brakes so that the right brake is often the front brake. This is done to allow the left hand to control speed while approaching obstacles requiring the bike to be carried, while the right hand grips the frame ready to lift

2112-487: 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 ( Flanders in particular), France and the Netherlands. Cyclo-cross has parallels with mountain bike racing , cross-country cycling and criterium racing. Many of

2160-554: The route profile (flats and hills), wind conditions, temperatures and elevation. At a 2013 event in Mexico, François Pervis achieved an average of 21.40 metres per second (77.0 km/h; 47.9 mph) with a flying start over 200 m (660 ft). The top average speed over the men's 1 km (0.6 mi) time trial at the 2004 Summer Olympics was 16.4 metres per second (59 km/h; 37 mph) recorded by Chris Hoy . Average speeds clearly drop with increasing distance, so that over

2208-430: The saddle. The sight of competitors struggling up a muddy slope with bicycles on their shoulders is the classic image of the sport, although unridable sections are generally a very small fraction of the race distance. Compared with many disciplines of road and track cycle racing, tactics are fairly straightforward, and the emphasis is on the rider's aerobic endurance and bike-handling skills. Drafting , where cyclists form

2256-461: The sport became more formalized, frame angles changed for quicker handling and bottom brackets heights were raised to clear broken ground. Most cyclo-cross frames have a non-compact (flat or near-flat top tube) frame design for easier shouldering. Some design features have recently begun to change, for example, a heightened bottom bracket was typical 10+ years ago; now many cyclo-cross-specific frames do not have elevated bottom brackets, in fact many have

2304-422: The winter months and put a twist on road racing. In addition, riding off-road in more difficult conditions than smooth pavement increased the intensity at which the cyclists were riding and improved their on-the-road bike handling abilities. Forced running sections, or portage , were incorporated to help deliver warm blood to the feet and toes, as well as exercise other groups of muscles. Daniel Gousseau of France
