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
Paris Marathon medal to all runners who finished the race in less than 4 hours. The distance of 40 km was chosen as it was the distance separating Marathon from Athens. The current distance of the race is 42.195 km, which the IAAF established in 1921 as the standard length of a marathon, following the 1908 Olympic race in London. This first race was won by Len Hurst from England who crossed the finishing line in 2 hours, 31 minutes and 30 seconds. His prize money was 200 francs.
