Physiology of marathons certain physiological characteristics of marathon runners exist. The differing efficiency of certain physiological features in marathon runners evidence the variety of finishing times among elite marathon runners that share similarities in many physiological characteristics. Aside from large aerobic capacities and other biochemical mechanisms, external factors such as the environment and proper nourishment of a marathon runner can further the insight as to why marathon performance is variable despite ideal physiological characteristics obtained by a runner. The first marathon ever run was an unintentional 25 mile trek performed by Pheidippides. Pheidippides was a Greek soldier who ran to Athens from the
Athens Classic Marathon point for both the 1896 and 2004 Olympic marathons. In 1982, the organisers dedicated the race to Grigoris Lambrakis, an athlete and Member of the Greek Parliament, whose murder in the 1960s has become an inspirational cause for advocates of human rights. Since 2007 the Association of International Marathons and Distance Races has organised an annual International Marathon Symposium in Marathon town the day prior to the race. Taking from the tradition of the Olympic Torch, the race features the Marathon Flame, which is lit at the Tomb of the Battle of Marathon and carried to the stadium in Marathon
