【第40回記念大会】東京豊洲ナイトマラソン 2026

Tokyo Toyosu Night Marathon is a summer evening running event in Tokyo's Koto Ward, staged as part of a recurring Sports One series. This edition marks the 40th anniversary event, and the race is built around running after dark rather than under the full heat of the day. The listing does not give a detailed route, but the event is clearly set up for hot-weather racing: runners get water splashing, water-station sponges, expanded pacer options, and staff cheering through to the finish. More than 8,000 people joined the previous edition, rankings are split in several ways so more runners can chase a high placing, photo spots are provided, and published results use bib numbers rather than personal names.
