The 1500 metres or 1,500-metre run (approximately mile) is the foremost middle distance track event in athletics. The distance has been contested at the Summer Olympics since 1896 and the World Championships in Athletics since 1983. The demands of the race are similar to that of the 800 metres, but with a slightly higher emphasis on aerobic endurance and a slightly lower sprint speed requirement. The 1500 metre race is predominantly aerobic, but anaerobic conditioning is also required.〔(1500 m - Introduction ). IAAF. Retrieved on 2012-02-07.〕 Each lap run during the world-record race run by Hicham El Guerrouj of Morocco in 1998 in Rome, Italy averaged just under 55 seconds (or under 13.8 seconds per 100 metres).〔(iaaf.org - 0 Toplists M - O )〕 1,500 metres is three and three-quarter laps around a 400-metre track. During the 1970s and 1980s this race was dominated by British runners, along with an occasional Finn, American, or New Zealander, but through the 1990s a large number of African runners began to take over in being the masters of this race, with runners from Kenya, Morocco, and Algeria winning the Olympic gold medals. In the Modern Olympic Games, the men's 1,500-metre race has been contested from the beginning, and at every Olympiad since. The first winner, in 1896, was Edwin Flack of Australia, who also won the first gold medal in the 800-metre race. The women's 1,500-metre race was first added to the Summer Olympics in 1972, and the winner of the first gold medal was Lyudmila Bragina of the Soviet Union. During the Olympiads of 1972 through 2008, the women's 1,500-metre race has been won by three Soviets plus one Russian, one Italian, one Romanian, one Briton, one Kenyan, and two Algerians. The best times for the race were controversially set by Chinese runners, all set in the same race on just two dates 4 years apart at the Chinese National Games. In American high schools, the mile run (which is 1609.344 metres in length) and the 1,600-metre run, also colloquially referred to as "metric mile", are more frequently run than the 1,500-metre run, since US customary units are better-known in America. Which distance is used depends on which state the high school is in, and, for convenience, national rankings are standardized by converting all 1,600-metre run times to their mile run equivalents.〔McCune R. R. (2011-07-11). (Verzbicas Breaks Four ). Lets Run. Retrieved on 2012-02-07.〕 ==Strategy== Many 1500 metres events, particularly at the championship level, turn into slow, strategic races, with the pace quickening and competitors jockeying for position in the final lap to settle the race in a final sprint. Such is the difficulty of maintaining the pace throughout the duration of the event, most records are set in planned races led by pacemakers who sacrifice their opportunity to win by leading the early laps at a fast pace before dropping out. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1500 metres」の詳細全文を読む スポンサード リンク
