Ultra-distance cycling
The definition of ultra-distance cycling is far more vague than in ultra running or in ultra-triathlon. Any bike race longer than a century ride, which is, is sometimes considered to be ultra-distance cycling. However, such events are relatively common, so using a longer distance to define the category is more useful, such as any race that is longer than, or even a double century,.
Bike races that cover these distances but which are split into stages do not fit most definitions of ultra-distance races - the clock needs to run continuously from start to finish. Even so, extra-long stages within a longer race may be long enough to be an ultra-distance race by themselves. In addition, any team events in which individual cyclists do not complete the full distance are not considered to be ultra-distance.
Bike races that can be described as ultra-distance are organized below according to the type or format of the race. This is not an exhaustive list of such races, but the longest, most important, or most popular races within each category are mentioned.
BikingMan is a series of 6 ultradistance self-supported cycling races which are all following a similar time-limit with a mileage of 620 miles.
Track cycling
In the early days of bicycle racing in the late 1800s, six-day racing on velodromes was popular. Only the original race format is a true ultra-distance cycling race as defined here because it was a simple test of how far an individual cyclist could ride during the six day-long event. The format evolved away from this to involve teams of two riding in a relay format. Later, the non-stop nature of the race was changed to only race during part of each day.Road racing
Professional
In the early days of professional road bicycle racing there were many one-day road races and stages in grand tours that were much longer than those of today. Bordeaux-Paris in France was the longest one-day, annual professional bike race; it had a route of about and was run almost every year between 1891 and 1988. After 1988, the longest one-day professional bike race became Porto–Lisboa in Portugal, which was about long. Porto-Lisboa was last held in 2004, and Milan-San Remo in Italy has since then been the longest race at.Paris–Brest–Paris was a professional bike race that covered a massive in France, and was only held every 10 years from 1891 until 1951, but has since continued as a randonneuring event.
Cycling's grand tours used to include far longer stages than they do today. The longest ever Tour de France stage was in the 1919 Tour and that year every one of the 15 stages was more than long. The longest ever stage in the Giro d’Italia was in the 1914 Giro and that year 5 of the 8 stages were longer than. The Vuelta a España did not begin until 1935 and the first edition was when its longest-ever stage was held, which was. In modern grand tours, stages longer than are increasingly rare and the limit set by the Union Cycliste Internationale for any individual stage during a stage race is 240 km.
Supported ultracycling races
There are no longer any true ultra-distance bike races that are affiliated with cycling's main governing body, the UCI; most modern ultra-distance races are instead affiliated with the . By far the best-known of these races is the Race Across America, a non-stop race across the United States that covers.In this format of racing, the cyclists race individually but each cyclist has at least one support vehicle and a team of support staff. This specific format of racing is often referred to as "ultracycling", which is why it would be incorrect to refer to all ultra-distance cycling as ultracycling. Many ultracycling races include a team category that operates in a relay format and so does not meet the criteria for an ultra-distance cycling race used here.
Other ultracycling races include the , which is long. The oldest ultracycling race in Europe is the , an Austrian cycling event with a distance of that was first held in 1997. The is only long but contains over of climbing and so the organizers claim it to be the hardest one-day race in the world.
The first Race Across Russia was held in 2013 as a non-stop team relay event with a total distance of about between Moscow and Vladivostok. In 2015 it became the with a solo category and the route was split into 15 separate stages, each between and long.
Road time trials
12-hour and 24-hour road cycling time trials have been around for a long time and are still common. In these events, cyclists attempt to ride the maximum distance possible within the time limit. The current 24 hour record is over on a traditional bicycle and over in a velomobile.In 2014, the UMCA revived interest in the highest annual mileage record, which was last set in 1939 by Tommy Godwin at. This involves riding the maximum distance possible within a 12-month period. In early 2016, Kurt Searvogel broke the record, achieving a distance of in one year or per day.
Some ultra-distance time trials are held at permanent motorsport racetracks, such as Bike Sebring, Rad am Ring, Monza 12h Cycling Marathon, Cycling Zandvoort 24h, 24h BiCircuit Festival, and Revolve24 Endurance Cycling Challenge. These lack any road traffic and have smooth road surfaces.
Unsupported ultracycling & bikepacking road races
Some races have recently become popular that recall the early era of professional bike racing in which riders were unsupported and raced day and night. The most popular of these is the Transcontinental Race, which covers approximately across Europe and was inspired by the off-road US event called the Tour Divide. As in ultra-cycling events, there is a mass start, but in bikepacking races, drafting is not allowed and all support is forbidden, so there are no support vehicles and riders must find all of their supplies, accommodation, etc. from commercial sources along the route or bring it with them. Although most will allow "Trail Magic" from strangers through kind actions, gifts, and other forms of encouragement so long as the magic doesn't move the bike. Another popular example in this category include the Trans Am Bike Race, which is more than 50% longer than the Transcontinental Race at, and so it is currently the longest non-stop bike race in the world. The IncaDivide, is a shorter distance event which brings the high altitude cycling experience. It is the highest self-supported race that takes riders above 4,920 meters in the Andes mountains of Peru. It is part of the BikingMan, the first ultra bikepacking race series which took place in 2019 in Oman, France, Laos, Peru, Portugal and Taiwan on 620 miles standard format.Unsupported rides are sometimes done as completely solo attempts outside of organized rides but are still well-publicized. These often involve riding point to point, for example .
Randonneuring
events are generally non-competitive rides where racing is not the focus; they are ridden more as personal challenges. They also differ from most ultracycling and bikepacking races in that group riding and drafting is allowed. Supplies and accommodation are often provided by the organizers at intermediate checkpoints, but the use of support vehicles is not allowed outside of the checkpoints.The most famous of this type of event is Paris-Brest-Paris in France, in which over 5,000 people attempt to complete the long route in under 90 hours. The randonnee version evolved from the professional bike race and is held every four years. There are many similar events of between and around the world, including London–Edinburgh–London in the UK and the in the USA. For a more complete list, see the page on randonneuring. There are also many more shorter-distance randonneuring rides, which are typically,, or long.
Cyclosportives / Gran fondos
s are mass-participation cycling events. They are far less serious than pure bike races, but times are recorded and prizes are often awarded to the fastest people. The organizers normally provide full support in terms of marking the route and providing feed stations.The event that proclaims itself to be the "longest Granfondo in the world" follows almost the same route as the professional Milan-San Remo bike race and is long. However, there are several similar events that are longer. Bordeaux-Paris was a professional race until 1988 and returned in 2014 as a cyclosportive with a route of about. is a long race and cyclosportive in Norway. The is a long cyclosportive over mountainous terrain through France, Switzerland, and Italy. Slightly longer still is the in Switzerland at. There is also the , which is a long ride around the island of Mallorca, the Dragon Devil version of the Dragon Ride Wales cyclosportive in the UK is long, and the Vätternrundan cyclosportive that does a tour of the Swedish lake is long.
In New Zealand, there is the Lake Taupo Cycle Challenge. The standard cyclosportive option involves a single lap of the lake, which is long, but there are also options to do two laps in one day for, with no support on the first lap, or start one day earlier and do four laps,, which is more of a randonneuring-format event. Every second year there is also an 8 lap option, long, but a following support vehicle is required for that version making it more of an ultracycling-format event.
Century rides
In the US, organized century rides of are common, with the format falling between a cyclosportive and a randonnee. There are also many organized double centuries of, one of the more popular ones being the Seattle to Portland Bicycle Classic, and at least one event even offers and options, the .Other road cycling records
There are a few classic long-distance cycling routes for which time records are kept even though riders normally do not race simultaneously. These include Land's End to John o' Groats in the United Kingdom, which is about. On the longer end of the spectrum, there is in Africa, which is about. This record is currently held by Scottish endurance cyclist Mark Beaumont. The longest record of this format is the around the world cycling record, which requires the cyclist to cover by bike plus other requirements. A new women's around the world cycling record is currently being attempted by Scottish endurance cyclist Jenny Graham. In 2012 and 2014, a mass-start event called the was organized based on these rules.Gravel biking
In the early days of road bike racing, most roads were not paved, so most races were held primarily on unpaved/dirt/gravel roads. Due to road infrastructure improving with time, road bike racing is now done almost entirely on paved roads. However, in the 21st century, riding and racing road bikes on gravel roads has gained popularity, at least in part due to improvements in technology.Bicycle technology is seen as the largest contributor to the popularity of gravel biking because technology has allowed designers to integrate key characteristics of bikes across disciplines into one bike. For instance, the relaxed geometry of mountain bikes is the foundation of gravel bike frames but gravel bikes are lighter, faster and more responsive than a mountain bike. Gravel bikes also use characteristics of both cycle cross and road bikes for better comfort on long rides and the wheel clearance to accommodate rides done in torrential conditions.
The culture of gravel biking has also been another reason it has grown in popularity. Gravel races rarely call for a team of coaches and bicycle technicians because the courses susceptible to varying weather that is hard to train and prepare for. Gravel riders are generally focused on getting through a course rather than maintaining a pace during races. This give way to camaraderie on the trail and caters to a fun and relaxed atmosphere that is not always present in road and mountain bike races.
One of the longest and most famous of the modern gravel bike races is the Dirty Kanza in the Flint Hills around Emporia, Kansas, USA, which is long with a 350-miler announced for 2018 and options of 25, 50 and 100 mile courses as well. In the UK, the is a 200 km off-road cycling challenge that takes place in Hexham, England.
The Dirty Kanza is a great example of how much gravel biking has grown in recent years for example, in 2006 there was a total of 34 riders that participated in the 200 mile race. In June 2019, 2,750 riders lucky enough to be picked from a lottery crossed the start line of the Dirty Kanza 200 and the fact that organizers had to introduce other mileage categories also shows that gravel biking is about the adventure.
Mountain biking
As on the road, some of the most popular ultra-distance mountain bike events are 12 and 24 hour time trials, of which there are many all over the world. In addition, there are many mountain bike races of at least. Very few mountain bike races are longer than because the average speed on typical mountain biking terrain is much slower than that on the road.24 hour mountain bike races are where the bikepacking genre began, in which riders are entirely self-supported. One of the most famous and popular off-road bikepacking events is the Tour Divide, which covers across the Rocky Mountains from Canada, through the US, and finishes at the Mexican border. The Iditarod Trail Invitational in Alaska is run on snow bikes in winter and is long. The most popular off-road bikepacking race in Europe is the Tuscany Trail, which covers in central Italy. Also in Italy, the Italy Divide starts at the Roman Coliseum and finishes at Lake Garda, passing through Siena, Florence and Bologna en route. It mixes technical mountain bike sections with gravel trails.
In Central Asia, the Silk Road Mountain Race takes place in Kyrgyzstan, and covers 1,700 km in the Tien Shan mountain range.
The Titan Desert is a six-day stage race held in Morocco with a total distance of over.
In Australia, the Race to the Rock is an unsupported race through the Outback founded by Jesse Carlsson. The course and length differs each year, but generally finishes at Uluru; the 2018 edition was 3,500 km in total, and covered sections of Southern Australia as well as Tasmania.
