The Tokyo Marathon will make its debut as a World Marathon Majors race Sunday with a potential race record in store in the men's competition.
Tokyo joins Boston, London, Berlin, Chicago and New York in the six-legged series contested over a two-year period. The winner receives $500,000.
The men's race on Sunday will feature four runners who own times of 2 hours, 4 minutes and will challenge the Tokyo Marathon record of 2:07:23, set by Viktor Rothlin in 2008. The fastest marathon ever run on Japanese soil is 2:05:18.
