Clarence DeMar DeMar did not return to serious competition until 1922, when he again won the Boston marathon in a course record 2:18:10. He repeated the victory in 1923 and 1924. In the latter year the full Olympic distance – 26 miles, 385 yards – was run. He was selected as one of the six runners on the U.S Olympic marathon team for the 1924 Summer Olympics, where he finished third. DeMar continued his success with a second-place finish at the 1925 Boston marathon, and a third-place finish the next year. He followed that with five consecutive marathon victories: at the Baltimore
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
