An ultramarathon, also called ultra distance or ultra running, is any footrace longer than the traditional marathon length of 42.195 kilometres. Various distances are raced competitively, from the shortest common ultramarathon of 50 kilometres (31 mi) to over 100 kilometres (62 mi). 50k and 100k are both World Athletics record distances, but some 100 miles (160 km) races are among the oldest and most prestigious events, especially in North America. Around 100 miles is typically the longest course distance raced in under 24 hours but there are also longer multi-day races of 200 miles (320 km) or more, sometimes raced in stages with breaks for sleep. While some ultras are road races, many take place on trails, leading to a large overlap with the sports of trail running and mountain running.
Trail running is a sport-activity which combines running, and, where there are steep gradients, hiking, that is run "on any unpaved surface". It is similar to both mountain and fell running. Mountain running may, however, include paved sections. Trail running normally takes place in warm climates, or on good paths, or tracks which are relatively easy to follow, and does not necessarily involve the significant amounts of ascent, or need for navigating skills, normal in fell running. Unlike road running and track running it generally takes place on hiking trails, often in mountainous terrain, where there can be much larger ascents and descents. It is difficult to definitively distinguish trail running from cross country running. In general, however, cross country is an IAAF-governed discipline that is typically raced over shorter distances.

Multiday races are ultramarathon running events which are typically either segmented into daily events of a specified distance or time, or staged so that runners can run as far as they want, at their own discretion, over a set course or over a set number of days. Multiday races can range from continuous 48-hour track events to staged transcontinental treks.

The Atacama Desert is a desert plateau in South America covering a 1,600 km (990 mi) strip of land on the Pacific coast, west of the Andes Mountains. The Atacama Desert is the driest nonpolar desert in the world, and the second driest overall, just behind some very specific spots within the McMurdo Dry Valleys as well as the only hot true desert to receive less precipitation than the polar deserts, and the largest fog desert in the world. Both regions have been used as experimentation sites on Earth for Mars expedition simulations. The Atacama Desert occupies 105,000 km2 (41,000 sq mi), or 128,000 km2 (49,000 sq mi) if the barren lower slopes of the Andes are included. Most of the desert is composed of stony terrain, salt lakes (salares), sand, and felsic lava that flows towards the Andes.

An ultra-triathlon covers more distance than a 'long course,' or Ironman triathlon. The term generally refers to all triathlon events with a distance that is a multiple of the Ironman Triathlon, which consists of 2.4 miles (3.86 km) of swimming, 112 miles (180.25 km) of cycling, and a full marathon of running. The most common distances are the double, triple, quadruple, quintuple and deca triathlon. Unlike a standard triathlon event, an ultra-triathlon event may not necessarily involve the three component disciplines of triathlon in direct consecutive order, but may instead consist of multiple consecutive individual triathlons performed on consecutive days, or may involve disciplines out of the usual order, such as the 'Arch to Arc' that goes run-swim-bike to allow crossing of the English Channel.

Ryan Nicholas Sandes "Hedgie" is a South African trail runner. In 2010 he became the first competitor to have won all four of the 4 Deserts races, each a 6/7-day, 250-kilometer (160 mi) self-supported footrace through the Atacama Desert in Chile, the Gobi Desert in China, the Sahara Desert in Egypt, and lastly Antarctica. His achievement prompted Mary Gadams, founder and CEO of RacingThePlanet and organiser of the event, to state “Ryan Sandes is clearly one of the top endurance athletes in the world - to have won all 4 Deserts is a remarkable accomplishment.” To date only 81 individuals have completed all four trails. 11 competitors have managed the 4 Deserts Grand Slam, that is, completing the four trails in a calendar year.
