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
Nagano Olympic Commemorative Marathon Shinmai Marathon which was first held in 1958. The marathon came under its current moniker in 1999. The elite race is international in nature, with a number of foreign runners being invited each year, although prominent Japanese athletes also take part. Kenyans have won the majority of the men's races while Russians have dominated the women's race. Nephat Kinyanjui of Kenya won the race a record three times consecutively between 2006 and 2008. Since its rebirth in 1999, only two Japanese runners have won the race (Akiyo Onishi in 1999 and Yuki Kawauchi in 2013). Key: Nagano Olympic Commemorative Marathon
