An ultramarathon, also called ultra distance or ultra running, is a footrace longer than the traditional marathon length of 42.195 kilometres. Various distances, surfaces, and formats are raced competitively, from the shortest common ultramarathon of 31 miles (50 km) and up to 3100 miles. World Championships are held by the International Association of Ultrarunners (IAU) for 50 km, 100 km, 24 hours, and ultra trail running. The Global Organization of Multi-Day Ultramarathoners (GOMU) holds World Championships for 48 hours and 6 days. World Records are ratified and recognized by World Athletics, the IAU, and by GOMU.
Fell running, also sometimes known as hill running, is the sport of running and racing, off-road, over upland country where the gradient climbed is a significant component of the difficulty. The name arises from the origins of the English sport on the fells of northern Britain, especially those in the Lake District. It has elements of trail running, cross country and mountain running, but is also distinct from those disciplines.

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.
Fastpacking is a combination of trail running and ultralight backpacking. It is described by writer Clint Cherepa as "hiking the ups, jogging the flats, and running the downs", depending on the gradient, because of the weight carried. Participants carry a light pack with essential supplies, including a sleeping bag and tent, or similar form of shelter, if mountain huts or other accommodation is not available. The weight carried will vary but fastpackers aim at no more than 15 pounds (6.8 kg) and some achieve less than 10 pounds (4.5 kg). This activity may be undertaken either unsupported, self-supported, or supported. "Unsupported fastpackers make no use of outside assistance along the route", while self-supported fastpackers will leave caches of supplies along the intended route.

The backyard ultra or last one standing is a form of ultramarathon race where competitors must consecutively run the distance of 6.706 kilometres (4.167 mi) in less than one hour, which is a pace of 100 miles per 24 hours. The race is over when only one runner remains to complete a lap. This runner is marked as the winner and only finisher, with all other runners receiving a "DNF". The runner who completes the second-most laps in a race is often referred to as the "assist", in the sense that their effort is ultimately what determines how long the race is allowed to continue--there is no predefined end length or time in a backyard ultra, as long as multiple runners can complete each loop within an hour.
