Mavis Hutchison

	Mavis Hutchison Mavis Hutchison (25 November 1924 – 19 May 2022) was a South African athlete, primarily known for running in ultramarathons. Career Born in South Africa, Hutchison's career began as a race walker, and her first record was in the 50-mile walk known as the Rand Daily Mail Big Walk in 1963 (9 hours 35 minutes). That same year she was timed over the standard marathon distance of 42.2 km, but took about ten minutes longer than Violet Piercy had done in 1926, and 13 minutes longer than Merry Lepper's time a few months later. In 1965, she was (as an unofficial entrant) the third woman in history to finish the 90 km of the Comrades Marathon, and the first since the 1930s. In later years she completed the race seven more times (1966, 1971, 1973, 1976, 1977, 1980, 1981). Hutchison went on to set new women's world records for the 100-mile and 24-hour run in 1971, and for the 100-mile and 24-hour walk in 1973. In 1973 Hutchison became the first woman to run the 602 km fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Ultramarathon An ultramarathon, also called ultra distance or ultra running, is any footrace longer than the traditional marathon length of . Various distances are raced competitively, from the shortest common ultramarathon of to over . 50k and 100k are both World Athletics record distances, but some 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 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. Overview There are two main types of ultramarathon events: those that cover a specified distance or route, and those that last for a predetermined period of time (with the winner covering the most distance in that time). The most common distances are , , , and , although many races have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	200 Metres The 200 metres, or 200-meter dash, is a sprint running event. On an outdoor 400 metre racetrack, the race begins on the curve and ends on the home straight, so a combination of techniques is needed to successfully run the race. A slightly shorter race, called the '' stadion'' and run on a straight track, was the first recorded event at the ancient Olympic Games. The 200 m places more emphasis on speed endurance than shorter sprint distances as athletes predominantly rely on anaerobic energy system during the 200 m sprint. Similarly to other sprint distances, the 200 m begins from the starting blocks. When the sprinters adopt the 'set' position in the blocks they are able to adopt a more efficient starting posture and isometrically preload their muscles. This enables them to stride forwards more powerfully when the race begins and start faster. In the United States and elsewhere, athletes previously ran the 220-yard dash (201.168 m) instead of the 200 m (2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Female Ultramarathon Runners Female (symbol: ♀) is the sex of an organism that produces the large non-motile ova (egg cells), the type of gamete (sex cell) that fuses with the male gamete during sexual reproduction. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes, unlike isogamy where they are the same size. The exact mechanism of female gamete evolution remains unknown. In species that have males and females, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Female characteristics vary between different species with some species having pronounced secondary female sex characteristics, such as the presence of pronounced mammary glands in mammals. In humans, the word ''female'' can also be used to refer to gender in the social sense of gender role or gender identity. Etymology a ...
