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
Marathon, Greece on account of the victory which the Athenians here gained over the Persians in 490 BCE (Battle of Marathon).
