Ultramarathoners compete at the Sahara Race 2011 (4 Deserts)

An ultramarathon, also called ultra distance or ultra running, is any footrace longer than the traditional marathon length of 42.195 km, 26.2 miles.


There are two types of ultramarathon events: those that cover a specified distance, and events that take place during time (with the winner covering the most distance in that time). The most common distances are 50 km, 100 km, 50 m, and 100 m, although many races have other distances. The 100 kilometers is recognized as an official world record event by the International Association of Athletics Federations (IAAF), the world governing body of track and field.

Other distances/times include double marathons, 24-hour races, and multiday races of 1000 m or even longer. The format of these events and the courses vary, ranging from single or multiple loops (some as short as a 400 m track),If the loop is less than 1 km, run direction changes every 2–4 (sometimes 6) hours to point-to-point road or trail races, to cross-country rogaines. Many ultramarathons, especially trail challenges, have severe course obstacles, such as inclement weather, elevation change, or rugged terrain. Many of these races are run on dirt roads or mountain paths, though some are run on paved roads as well. Usually, there are aid stations every 20-35 km apart, where runners can replenish food and drink supplies or take a short break. Timed events range from 6, 12, and 24 hours to 3, 6, and 10 days and longer, known as multiday events. Timed events are generally run on a track or a short road course, often one mile (1.6 km) or less.

The International Association of Ultrarunners (IAU) organises the World Championships for various ultramarathon distances, including 50 km, 100 km, 24 hours, and ultra trail running, which are also recognized by the IAAF. Many countries around the world have their own ultrarunning organizations, often the national athletics federation of that country, or are sanctioned by such national athletics organizations. World records for distances, times, and ages are tracked by the IAU.

Racewalking events are usually 50 km, although 100 km and 100 mile (160 km) "Centurion" races are also organized. Furthermore, the non-competitive International Marching League event Nijmegen Four Days March has a regulation distance of 4 × 50 km over three days for men aged 19–49.

Oceania, Australia, and New Zealand[edit]

Australia and New Zealand are hosts to some 100 organized ultramarathons each year. Additionally a handful of runners have run the entire length of New Zealand, a distance of around Template:Convert.[31] The most recent runner's being Lisa Tamati and Andrew Hedgman who both completed the challenge separately in 2009 and 2010.


In Australia, the Westfield Ultra Marathon was an annual race between Sydney and Melbourne contested between 1983 and 1991. Greek runner Yiannis Kouros won the event five times during that period. Australia is also the home of one of the oldest six-day races in the world, the Cliff Young Australian 6-day race, held in Colac, Victoria. The race is held on a 400-meter circuit at the Memorial Square in the centre of Colac, and has seen many close races since its inception in 1984. The 20th Cliff Young Australian six-day race was held between 20 and 26 November 2005. During that event, Kouros beat his existing world record six-day track mark and set a new mark of Template:Convert. The Coast to Kosciuszko inaugurated in 2004, is a Template:Convert marathon from the coast to the top of Mount Kosciuszko, Australia's highest mountain.

Australia has seen a steep growth in Ultrarunning events and participants in recent years. Many new races have come into inception, covering a range of Ultramarathon distances from 50 km right through to multi-day events. The cornerstone of Australian Ultra events being such races as; Ultra-Trail Australia 100, Bogong To Hotham, Alpine Challenge, and the Cradle Mountain Run.[32] The Australian Ultra Runners Association (AURA) has a comprehensive list and links of events and their respective results.[33]

New Zealand[edit]

New Zealand's first ultramarathon called The Kepler Challenge was held on a Template:Convert trail through Fiordland National Park, which has been running since 1988 and is one of the country's most popular races. New Zealand's Northburn 100 ultra mountain run is the first 100-mile (160 km) race through the Northburn Station. The world-famous Te Houtaewa Challenge has a 62 km race on ninety mile beach, Northland. The field of international and local runners have to contend with rising tides and soft beach sand and the March race dates often means the race is run in the cyclone season. In 2014 the ultramarathon was postponed because of Cyclone Lucy. In 2016 the race will be in its jubilee and the 25th anniversary will see many of its past runners compete for the honour of the ultimate challenge winner.

In November 2012, Kim Allan planned to run and/or walk Template:Convert nonstop, without sleep, on the Sri Chinmoy Peace Mile track at the Auckland Domain. Her aim was to beat ultrarunner Pam Reed's record of Template:Convert.[34] According to her Facebook page, she only managed Template:Convert. She eventually passed the 500 kilometre mark at 86 hours, 11 minutes, and 9 seconds, breaking the Template:Convert women's record.[35]

In April 2013, a Feilding man, Perry Newburn, set a new New Zealand record by running Template:Convert without sleep at Feilding's Manfield Park.[36]

Ultramarathon running in New Zealand has a national body: the New Zealand Ultrarunners Association.


Papua New Guinea has the Kokoda Challenge Race, an annual 96 km endurance race held in late August that runs the length of the historic Kokoda Track.[37]

Papua New Guinea also has the The Great Kokoda Race, a multi-stage 96 km (3 day) race held in early July where competitors run or walk the length of the Kokoda Track.[38]


In Europe, ultrarunning can trace its origins with early documentation of ultrarunners from Icelandic sagasTemplate:Citation needed, or the antique Greece from where the idea of the Marathon, and the Spartathlon comes. The history of ultrarunners and walkers in the UK from the Victorian Era has also been documented. The IAU hosts annual European Championships for the 50 km, 100 km and 24 hours.

There are over 300 ultramarathons held in Europe each year.Template:Citation needed


Due to logistics and environmental concerns there are only a handful of ultramarathons held in Antarctica, and travel costs can mean entrance fees as high as $14,000.[39] Ultramarathons in Antarctica include: The Last Desert, part of the 4 Deserts Race Series, a multi-stage footrace, and the Antarctic Ice Marathon – a marathon and 100-kilometer race.

North America[edit]

There are several hundred ultramarathons held annually in North America. One of the best known is the Western States Endurance Run, the world's oldest 100-mile trail run. The race began unofficially in 1974, when local horseman Gordy Ainsleigh's horse for the 100-mile Tevis Cup horse race came up lame. He decided to travel the course on foot, finishing in 23 hours and 47 minutes.Template:Citation needed

One of the first documented ultramarathons in North America was held in 1926, and at the time was part of the Central American Games. Tomas Zafiro and Leoncio San Miguel, both Tarahumara Indians, ran 100 km from Pachuca to Mexico City in 9 hours and 37 minutes. At the time, the Mexican government petitioned to include a 100 km race in the 1928 Summer Olympics in AmsterdamTemplate:Citation needed; however, nothing came of these efforts.

100 Mile Footraces in the Contiguous United States, 2011

In 1928, sports agent C. C. Pyle organized the first of two editions of the 3,455-mile-long Bunion Derby (the first went along U.S. Route 66 from Los Angeles to Chicago before heading toward New York; the 1929 Derby reversed the route). Neither the race nor the accompanying vaudeville show was a financial success.

Since 1997, runners have been competing in the Self-Transcendence 3100 Mile Race, which is billed as the longest official footrace in the world. They run 100 laps a day for up to 50 days around a single block in Queens, NY, for a total distance of Template:Convert.[11] The Latest Trans-American Footrace (2015) winner was Robert HP Young (Marathon Man UK) Winning in a time of 482 hours 10 minutes 00 seconds [40]

In April 2006, the American Ultrarunning Hall of Fame was established by the American Ultrarunning Association (AUA). Candidates for the Hall of Fame are chosen from the 'modern era' of American ultras, beginning with the New York Road Runners Club 30 Mile race held in 1958. The Inaugural inductees were Ted Corbitt, a former US Olympian, winner of the aforementioned race in 3:04:13, and co-founder of the Road Runners Club of America, and Sandra Kiddy, who began her ultra career at age 42 with a world record at 50 kilometers, 3:36:56, and who went on to set a number of US and world ultra records.

South America[edit]

There are a small number of ultramarathons in South America, but participation in the sport is increasing. The Brazil 135 Ultramarathon is a single-stage race of 135 miles ( 217 km) with a 60-hour cutoff, held in Brazil. This is a Badwater "sister race".[41] Several ultramarathons are held in Chile and with both local and international participation.[42] Ultramarathons held in Chile include:

  • Atacama Xtreme 50K, 80K and the first 100 Miles in Chile. One loop for each distance starting and finishing in San Pedro de Atacama at an avg. of 2,400 above sea level.[43]
  • The Endurance Challenge, a 10K, 21K, 50K and 80K trail running race held in the Andes mountain range near Santiago. It is part of the global Endurance Challenge circuit. The race seeks to promote the sport, outdoor activity and the use of mountain trails, taking care to have the lowest impact possible on the environment.
  • The Lican Ray-Villarrica Ultramarathon, a 70 km marathon that starts in Lican Ray, climbs Villarrica Volcano and ends in downtown Villarrica.
  • The Atacama Crossing, established in 2004, a 250 km (155 mile) ultramarathon which takes place in the Atacama desert, around San Pedro de Atacama, Chile[44] and crosses through the driest place on earth. There are six stages in seven days, with almost four marathons run in the first four days, then a 74 km stretch, then a rest day and a final stage of 11 km. It is part of the 4 Deserts Series. The race covers rugged terrain, with a harsh climate and an altitude that averages 2500 m (8000 ft). The race uses the town of San Pedro de Atacama as its host town, and in 2012 the race began at its highest point of over 3,000m in the Arcoiris Valley.
View from the Atacama Crossing 2011.
  • The Patagonian International Marathon, organized by NIGSA, takes place in Torres del Paine National Park, southern Chilean Patagonia. The event features four race distances: an ultramarathon (63 km), marathon (42 km), half marathon (21 km) and a 10K. Each distance has a different starting point, but everyone finishes in the same place. The event has the secondary goal of promoting the conservation of Chilean Patagonia and contributing to the sustainable development of the region through the planting of trees in the Torres del Paine National Park through the "Corre y Reforesta" (Run and Reforest) campaign[45] run by the organization "Reforestemos Patagonia" (Let's Reforest Patagonia)[46]
  • The Rapa Nui GrandTrail, an 80k ultramarathon that takes place on Easter Island, Valparaíso Region, Chile. This exotic trail, far out in the Pacific Ocean, takes in the famous Moai statues of the island.[47]

International Trail Running Association (ITRA)[edit]

Many ultramarathon organizers are members of the International Trail Running Association (ITRA), an organization which promotes values, diversity, health and safety during races, as well as working to further the development of trail running and helps to coordinate between the national and international bodies with an interest in the sport. ITRA also evaluates of the difficulty of specific ultramarathon routes according to a number of criteria, such as the distance, the cumulative elevation gain, and the number of loops and stages. ITRA maintains a calendar of ultramarathon events.

Born to Run[edit]

In 2009, Christopher McDougall's book Born to Run was released. It contained both anthropological and scientific information, and is about a society of ultramarathoners. It was not the first book written specifically about ultramarathons, but McDougall included controversial conclusions about humanity's roots in long distance running that attracted attention to the sport. It became a national bestseller and a Forbes and Washington Post book of the year.
