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.
Beyond the marathon
Very long endurance running events can be divided into three broad categories: the traditional 26.2-mile (42.2 km) marathon, the ultramarathon, defined as any event longer than the marathon, and true multiday events, which begin with the 48-hour event and can stretch out almost indefinitely, often ranging from six days to 3,000 miles (4,800 km) or longer.
Ultramarathons, of which multiday races are a subset, include events of any distance beyond the traditional marathon distance of 42.195 kilometres (26.219 mi). Common ultra events include 100-mile (160 km) and 100 kilometer races. Ultras are usually considered to include all events of 50 kilometers or longer, although the 50-mile (80 km) race is regarded as the shortest true ultra. Depending on the degree of terrain difficulty, up to 30 hours or more is generally allowed for runners to complete typical ultras, for example the Badwater Ultramarathon.
Types of courses
Many multiday races are held on tracks or measured loops, which eases provision of aid station support for runners. Stage races are the alternative; these include point to point races such as the Trans-American races, which traverse the North American continent coast to coast, and the Gobi March, a seven-day journey across the Gobi desert, the Kalahari Augrabies Extreme Marathon, a 7-day, 250 km trail event in the Kalahari Desert, and the Yukon Arctic Ultra, a 430/300/100/26 mile challenge crossing Yukon in the dead of winter.
Longer multiday races include the Trans-Europe race, which ran from Lisbon to Moscow in 2003, a distance of about 5,100 kilometers. These events take the runner to a different level, where the race becomes a way of life and where nutrition, sleep, energy and psychological states have to be carefully managed. The Self-Transcendence 3100 Mile Race is the longest certified footrace in the world.
The golden era of multiday races stretches back to the 1870s and 1880s, when they were held on indoor tracks and offered substantial prizes. Known as pedestrians, these athletes established records which in some cases have stood until recently. In summer 1809 in Newmarket, England, Robert Barclay Allardice, better known as Captain Barclay, ran/walked one mile (1.6 km) for each consecutive hour, each consecutive day, totalling 1,000 miles (1,600 km).
The most common multiday race of the era was the six-day race, which ran from Monday to Saturday with Sunday being observed as a rest day. In 1878, Sir John Dugdale Astley was inspired to create a series of five international six-day races, in which competitors vied for the Astley Belt. Two early competitors were the American Edward Payson Weston, who covered 500 miles (800 km) in 6 days. The Englishman Charles Rowell covered 241 km in the first day of a 6-day races in the 1880s.
By the early 1890s, public enthusiasm for such events had moved into bicycle racing, and the multiday running craze came to an end. Interest grew again in the late 1920s, with the advent of Trans-America races. These events were transcontinental stage races that inspired a new generation to challenge the huge distance. There was little reward for these races in the long run, and it was not until the 1980s that interest re-awoke in true multi-day races. In 1980, San Francisco postal delivery worker Don Choi organized the first modern era six-day race, on a track in Woodside, California.
In recent years, several multi-day races have stood out, among them the Australian Westfield Sydney to Melbourne races, which were run from 1983–1991, and the Colac (1983–2005) race which is no longer being held. August 2012 will see possibly the final 64 stage Trans-Europe race organised by Ingo Schulze. Sri Chinmoy Races hosts several multi-day events annually in the US: six- and ten-day races, a 3,100-mile (5,000 km)race, 700-, 1,000- and 1,300-mile (2,100 km) races, and several 24- and 48-hour events in Europe, Asia, Australia and New Zealand. Trans-Gaule, Trans-Germany - the Deutschlandlauf, Trans-Korea as well as occasional Trans-Am and Trans-Australia races plus several 6 day events in Europe and South Africa. The RacingThePlanet's 4 Deserts Race Series and the Marathon des Sables are among the most popular multiday races taking place today.
