Hour record
Record for the longest distance cycled in one hour on a bicycle
Record for the longest distance cycled in one hour on a bicycle
The hour record is the record for the longest distance cycled in one hour on a bicycle from a stationary start. Cyclists attempt this record alone on the track without other competitors present. It is considered one of the most prestigious records in cycling. Since it was first set, cyclists ranging from relatively unknown amateurs to well-known professionals have held the record. There is now one unified record for upright bicycles meeting the requirements of the Union Cycliste Internationale (UCI). Hour-record attempts for UCI bikes are made in a velodrome.
Early hour records (until 1972)
The first universally accepted record was in 1876 when the American Frank Dodds rode 26.508 km on a penny-farthing. The first recorded distance was set in 1873 by James Moore in Wolverhampton, riding an Ariel 49" high wheel (49 in) bicycle; however, the distance was recorded at exactly 14.5 miles, leading to the theory that the distance was just approximated and not accurately measured.
The first officially recognised record was set by Henri Desgrange at the Buffalo Velodrome, Paris in 1893 following the formation of the International Cycling Association, the forerunner of the modern-day UCI. Throughout the run up to the First World War, the record was broken on five occasions by Swiss rider Oscar Egg and Frenchman Marcel Berthet, and due to the attempts being highly popular and guaranteeing rich attendances, it is said that each ensured he did not beat the record by too much of a margin, enabling further lucrative attempts by the other.
The hour was attempted sporadically over the following 70 years, with most early attempts taking place at the Buffalo Velodrome in Paris, before the Velodromo Vigorelli in Milan became popular in 1930s and 1940s sparking attempts from leading Italian riders and former Giro d'Italia winners such as Fausto Coppi and Ercole Baldini. Coppi's record set in 1942, during the Second World War, despite Milan being bombed nightly by Allied forces, was eventually broken in 1956 by Jacques Anquetil on his third attempt. In 1967, 11 years later, Anquetil again broke the hour record, with 47.493 km, but the record was disallowed because he refused to take the newly introduced post-race doping test. He had objected to what he saw as the indignity of having to urinate in a tent in front of a crowded velodrome and said he would take the test later at his hotel. The international judge ruled against the idea, and a scuffle ensued that involved Anquetil's manager, Raphaël Géminiani. In 1968, Ole Ritter broke the record in Mexico City, the first attempt at altitude since Willie Hamilton in 1898.
The women's hour record was first established in 1893 by Mlle de Saint-Sauveur at the Vélodrome Buffalo in Paris, setting a total distance of 26.012 km. The record was improved several times over the next years, until Louise Roger reached 34.684 km in 1897 also at Vélodrome Buffalo. In 1911 the longest standing men's or women's record (37 years) was set by the 157 cm (5 ft 2 in) tall Alfonsina Strada: 37.192 km riding a 20 kg (44 lbs) machine. From 1947 to 1952, Élyane Bonneau and Jeannine Lemaire set several new hour records, the last of which was 39.735 km by Lemaire in 1952. The first women's hour record approved by the UCI was by Tamara Novikova in 1955. However Lemaire's 1952 non-UCI record was not bettered until Elsy Jacobs broke the 40 kmh barrier in 1958, the year Jacobs had won the inaugural women's road world championship. Jacobs' 1958 41.347 km UCI record would not be bettered until 1972.

UCI hour record (1972–2014)
1972–1984: Merckx, Moser and new technology
In 1972, Eddy Merckx set a new hour record at 49.431 km in Mexico City at an altitude of 2300 m where he proclaimed it to have been "the hardest ride I have ever done".
The record stood until January 1984, when Francesco Moser set a new record at 51.151 km. This was the first noted use of disc wheels, which, along with Moser's skin suit, provided aerodynamic gains. Moser's record would eventually be moved in 1997 to "best human effort".
1990s: non-traditional riding positions
In 1993 and 1994, Graeme Obree, who built his own bikes, posted two records with his hands tucked under his chest. In 1994, Moser set the veteran's record in Mexico City, riding 51.840 km with bullhorn handlebars, steel airfoil tubing, disk wheels and skinsuit. Moser's distance beat his 1984 record and Obree's 1993 ride.
In May 1994, the UCI outlawed the "praying mantis" style. Spaniard Miguel Induráin and Swiss Tony Rominger subsequently broke the record with a more traditional tri-bar setup; Rominger rode 55.291 km.

Chris Boardman took up the challenge using a modified version of the Lotus 110 bicycle, a successor to the earlier Lotus 108 bicycle he'd ridden to victory at the 1992 Olympic Games. South African company Aerodyne Technology built the frame. Boardman set the UCI Absolute record of 56.375 km in 1996, using another position pioneered by Obree, his arms out in front in a "Superman" position. This too was considered controversial by the UCI, and while the record was allowed to stand, the position was banned. This enabled Boardman's 1996 record to stand for about 26 years. In October 2022, Filippo Ganna unified the records, beating Boardman's best human effort record and Daniel Bigham's official UCI Hour record on a traditionally shaped, though uniquely manufactured, bicycle.
1997 UCI rule change
With the increasing gap between modern bicycles and what was available at the time of Merckx's record, the UCI established two records in 1997:
- UCI Hour Record: which restricted competitors to roughly the same equipment as Merckx, banning time trial helmets, disc or tri-spoke wheels, aerodynamic bars, and monocoque frames.
- Best Human Effort: also known as the UCI "Absolute" Record in which modern equipment was permitted.
As a result of the 1997 rule change, all records since 1972, including Boardman's 56.375 km in 1996, were moved to Best Human Effort and the distance of Eddy Merckx set in 1972 once more became the official UCI benchmark. In 2000, Boardman attempted the UCI record on a traditional bike, and rode 49.441 km, topping Merckx by 10 m, an improvement of 0.02%.
In 2005, Ondřej Sosenka improved Boardman's performance at 49.700 km using a 54×13 gear. However, Sosenka failed a doping control in 2001 and then again in 2008, the latter resulting in a career-ending suspension which puts in doubt the validity of his record. All women's records from 1986 to 1996 were recategorized to Best Human Effort.

UCI unified hour record (2014–present)
Unified rule change (2014)

In 2014, the UCI unified the two classifications into a single classification in line with regulations for current track pursuit bikes. Records previously removed for Chris Boardman and Graeme Obree were returned, however the benchmark record would remain at 49.7 km set in 2005 by Ondrej Sosenka, even though that was not the farthest distance. Under the new regulations riders may use any bike allowed by the UCI standards for endurance track events in place at the time of the attempt.
Riders are required to be part of the athlete biological passport program. However, of the men to attempt the record since the rule change, only five were on a UCI World Tour team at the time: Jens Voigt of Trek Factory Racing, Rohan Dennis of the BMC Racing Team, Alex Dowsett of the , Victor Campenaerts of Lotto Soudal, Filippo Ganna of Ineos Grenadiers. Matthias Brändle was with IAM Cycling, then a UCI Professional Continental team. Jack Bobridge was on Team Budget Forklifts, an Australian UCI Continental team. Thomas Dekker had been released from World Tour team Garmin–Sharp several months before. Gustav Larsson was riding for the Professional Continental team Cult Energy Pro Cycling, whilst Bradley Wiggins had left the World Tour's shortly before his attempt, which was made in the colours of his own UCI Continental team .
As of October 2022, 26 attempts have been made for the men's record, eight successfully, while nine attempts have been made on the women's record, six of them successfully.
Unified hour record attempts (men's)
Following the change in the rules, German Jens Voigt became the first rider to attempt the hour, on 18 September 2014 at the Velodrome Suisse, Grenchen, Switzerland. He set a new record of 51.110 km, beating the previous record set by Sosenka by 1.41 km. On 30 October 2014, Matthias Brändle set a new record of 51.852 km at the World Cycling Center in Aigle, Switzerland.
Further attempts by Australians Jack Bobridge and Rohan Dennis, and the Dutchman Thomas Dekker came within a few weeks, between 31 January and 25 February 2015. Dennis was the only one of the three to set a new record, and in doing so was the first rider to cover more than 52 km. Dekker's attempt at the Aguascalientes Bicentenary Velodrome was the first attempt to take place at appreciable altitude. Aguascalientes is at 1890 m above sea level, while Melbourne is at only 31 m, and, although in Switzerland, Grenchen and Aigle are at 451 m and 415 m respectively, and not in the mountains. High altitude is thought to result in faster times, providing the rider takes the time to acclimatise to the conditions. This is because the air density decreases with an increase in altitude, which reduces the aerodynamic drag.
Having postponed an earlier scheduled attempt due to a broken collarbone incurred in a crash while training, British cyclist Alex Dowsett exceeded Dennis's mark, with a new record of 52.937 km, at Manchester Velodrome on 2 May 2015.
On 7 June 2015, Sir Bradley Wiggins broke Dowsett's record, by completing a distance of 54.526 km at the Lee Valley VeloPark in London.
On 16 April 2019, Victor Campenaerts was the first to exceed 55 km/h by completing a distance of 55.089 km at the Velodromo Bicentenario in Aguascalientes.
The UCI rules require an athlete to participate in its anti-doping system, including having a biological passport. When Daniel Bigham rode 54.723 km to break Wiggins's British national record on 1 October 2021 he was ineligible to attempt the UCI record as he was not part of the anti-doping system, estimating it would cost him £8,000.

Unified hour record attempts (women's)
The last women's hour record before the unified rule change was set on 1 October 2003 by Leontien van Moorsel, with a distance of 46.065 km.
In December 2014, it was announced that British Paralympian Sarah Storey would be the first woman to attempt the record following the unified rule change. She attempted the record on 28 February 2015 at Lee Valley Velo Park in London, setting new British, Para-Cycling and Masters Age 35–39 records but missing out on the Elite record with a distance of 45.502 km.
American Molly Shaffer Van Houweling broke the women's UCI Hour Record, riding a distance of 46.273 km on 12 September 2015 in Aguascalientes, Mexico. Van Houweling had set three new US Hour Records in the year prior. The first was set on 15 December 2014, in Carson, California, with a distance of 44.173 km. The second was set on 25 February 2015, in Aguascalientes with a distance of 45.637 km. The third was set on 3 July 2015, also in Aguascalientes, with a distance of 46.088 km. This last mark was also the Pan-American and World Masters Age 40–44 record at the time, and exceeded the distance of the UCI hour record of van Moorsel. However, it did not qualify as the UCI Hour Record because Van Houweling had only been enrolled in the athlete biological passport program for three and a half months prior to setting this record. The UCI requires that riders be enrolled in this program for 5–10 months before they are eligible to set this mark. From 24 August 2015, Van Houweling was eligible to attempt the UCI Hour Record.
In October 2015, Australian rider Bridie O'Donnell announced her intention to aim for the hour record in January 2016. She broke the women's hour at the Adelaide Super-Drome on 22 January 2016, riding 46.882 km. She was aged 41 years. Her record was broken by American rider Evelyn Stevens in the next month - the new record was 47.980 km, more than a kilometre nearer to the 50 km barrier.
Italian rider Vittoria Bussi, after two unsuccessful attempts on 7 October 2017 and on 12 September 2018, broke Stevens' world record by 27 metres riding 48.007 km on 13 September 2018.
British cyclist Joss Lowden set a new world record on 30 September 2021 with a distance of 48.405 km, beating the previous record by just under 400 metres, and also surpassing Jeannie Longo's Best Human Effort distance. Lowden completed a total of 193 laps of the Tissot Velodrome in Grenchen, Switzerland.
On October 13, 2023, Vittoria Bussi set the world record again, at the Velodromo Bicentenario in Mexico, with a 50.267 km distance.

Para-cycling records
The new regulations for the making of accepted hour record attempts were extended to para-cycling in 2016. Although the first attempt on the hour record for women after the amendments to the regulations was made by Paralympian Sarah Storey, it was not a ratified attempt on the women's C5 hour record under the new conditions, which at that point still did not extend to paracycling – albeit that Storey's effort is recognized as a best C5 performance under the new rules, in addition to a British and masters world hour record in able-bodied cycling.
The first attempt on a para-cycling hour record after the new regulations were extended to para-cycling was by Irishman Colin Lynch in the C2 category, bettering the accepted best performance previously set by Laurent Thirionet in 1999 by 2 kilometres, and setting the first 'ratified' para-cycling world hour record. The mark of 43.133 km was achieved on 1 October at the National Cycling Centre in Manchester, Great Britain.

Timing of the record
At the conclusion of the hour, the rider is inevitably part-way round a lap. They complete that lap (meaning they actually cycle for more than an hour). The distance completed in the hour is determined by adding the fraction of that final lap, calculated from the ratio of the time remaining at the start of that lap to the time taken for that lap, to the preceding completed laps.
Times are required to be measured to a thousandth of a second. Distances are rounded down to a complete metre and records can be beaten only by at least one metre.
