来自古希腊地名Marathon,字面意思为茴香，即长满茴香的土地。来自公元前490年，在Battle of Marathon战役中，希腊联军打败了波斯军队，战士Pheidippides从Marathon一路不停奔跑将这一喜迅传达给雅典，最后力竭而死。其路程约为42.195公里，后为纪念他，在1896年首次在雅典举行的奥林匹克运动会上设置了这一比赛项目，即marathon race.
英文词源
marathon
marathon: [19] According to tradition, when the Greek army defeated the Persians at Marathon, on the northeast coast of Attica, in 490 BC, the runner Pheidippides was dispatched to bring the good news to Athens (in fact there is no contemporary evidence for the story, which is not recorded until 700 years after the event). When the modern Olympic Games were first held, in Athens in 1896, a long-distance race was introduced to commemorate the ancient feat, run over a course supposedly equal in distance to that from Marathon to Athens (about 35 km/22 miles).
The present distance (42.195 km/26 miles 385 yards) was established at the 1908 London Olympics (the odd yards were added to bring the finishing line in front of the royal box).
marathon (n.)
1896, marathon race, from story of Greek hero Pheidippides, who in 490 B.C.E. ran the 26 miles and 385 yards to Athens from the Plains of Marathon to tell of the allied Greek victory there over Persian army. The original story (Herodotus) is that he ran from Athens to Sparta to seek aid, which arrived too late to participate in the battle. Introduced as an athletic event in the 1896 revival of the Olympic Games, based on a later, less likely story, and quickly extended to mean "any very long event or activity." The place name is literally "fennel-field." Related: Marathoner (by 1912).
