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 (as measured by the level of media interest), or most popular (as measured by the number of participants) races within each category are mentioned. BikingMan is a series of six ultradistance self-supported cycling races which are all following a similar time-limit (120 hours) with a mileage of 620 miles.


Track cycling

In the early days of bicycle racing in the late 1800s,
six-day racing Six-day cycling is a track cycling event that competes over six days. Six-day races started in Britain, spread to many regions of the world, were brought to their modern style in the United States and are now mainly a European event. Initially, i ...

s 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.

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 Paris–Brest–Paris (PBP) is a long-distance cycling event. It was originally a 1,200 km () bicycle race from Paris to Brest and back to Paris in 1891. The last time it was run as a race was 1951. The most recent edition of PBP was held on 18 ...

Supported ultracycling races

There are no longer any true ultra-distance bike races (i.e., that are longer than ) that are affiliated with cycling's main governing body, the UCI; most modern ultra-distance races are instead affiliated with the World Ultra-Cycling Association (WUCA). By far the best-known of these races is the

(RAAM), a non-stop race across the United States that covers . In this format of racing, the cyclists race individually ( drafting and group riding are not allowed) 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 (in which individuals must ride the complete distance). Other ultracycling races include the Race ACross Europe (RACE), which is long. The oldest ultracycling race in Europe is the Glocknerman, an Austrian cycling event with a distance of that was first held in 1997. The Race Across The Alps 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 Red Bull Trans-Siberian Extreme with a solo category and the route was split into 15 separate stages, each between and long.

. 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. Since Kurt Searvogel's record year, Ms. Amanda Coker significantly surpassed Kurt's annual mileage record with a new record of over 86,000 miles in 365 days. Amanda continued on to break the record for fastest time to 100,000 miles, at approximately 420 days. Some ultra-distance time trials are held at permanent motorsport racetracks, such as Bike Sebring (

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. Among the most popular of these is the
Transcontinental Race The Transcontinental Race (TCR) is an annual, self-supported, ultra-distance cycling race across Europe. It is one of the world's toughest ultra-endurance races. The route and distance varies for each edition between about 3,200 and 4,200 km, ...

. As in other ultra-cycling events there is a mass start, but in bikepacking races drafting is not allowed and all support is forbidden. 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. Most events will, however, allow "trail magic" from strangers through kind actions, gifts, and other forms of encouragement so long as the "magic" does not move the bike. Other popular examples in this category include the

These often involve riding point to point (including city to city), for example Vegas In 24.


Randonneuring

events (also called brevets or audaxes) 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, with limits. 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 (see above) and is held every four years. There are many similar events of between and around the world, including

s (also known as gran fondos) 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 .

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 event.

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

s 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 cyclocross 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

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.
