About the Event

Under the slogan 'Run on the sea breeze', the Koto Seaside Marathon began in 1981 and reaches its 44th edition. The course runs through the old streets of Fukagawa and Joto and then the bay area that formed the heart of the Tokyo 2020 Games, with plenty of water and greenery along the way. The start is at Yumenoshima. The 10 km and half marathon (21.0975 km) are on the program, and the entry fee includes an administration fee, the event program and accident insurance. This listing is the general entry, decided by lottery.
