About

The EcoMarathon Futakotama d'Octobre takes place on 25 October 2026 at Tamagawa, in Tokyo's Setagaya ward, on a flat, fast waterside course. Three events are on offer: a half marathon (21.1 km), a 10 km and a 5 km parent-and-child race open to under-15s, all with a shared 11am start and a cap of 300 participants in total.

The event is run by an organisation involved in several charitable causes across Japan, including in Tokyo, Saitama, Osaka, Hiroshima, Kyoto and Kumamoto. Entrants can replace their entry fee with a donation, and funds raised go to Second Harvest Japan and to an international refugee support organisation.
