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 over the Persians. The provenance of the competitive race is traced back to the Marathon race at the 1896 Olympics. The Athens Classic Marathon began in 1972 as a joint venture between the Greek tourist board and athletics association. The race came under the auspices of the current organisers and SEGAS in 1983 and has since become a major race, being awarded Gold Label Road Race status by the IAAF. The 1983 event was known as the Athens Peace Marathon and both a popular and elite level race featured for the first time that year. It is perhaps the most
