第84回 スポーツメイトラン東大島小松川公園ハーフマラソン 2026

The Sports Mate Run Higashi-Ojima Komatsugawa Park Half Marathon is a local race held on the Arakawa riverbank, situated below Oshima Komatsugawa Park and a 15-minute walk from Higashi-Ojima Station. The primary event is a half marathon with a 3-hour time limit. The race also includes 10 km, 5 km, 3 km, and a 3 km parent-child run. With a participant cap of 500, it offers a community feel rather than a large-scale city marathon. Sports Mate organizes the event, providing automatic timing and finish certificates printed on the day for those seeking an official record. The course follows an out-and-back route of approximately 2.5 km in each direction, looping around Oshima Komatsugawa Park and extending upstream towards Hirai Ohashi. It is a flat and accessible course, offering runners ample park and riverbank scenery within Tokyo. The event accommodates a range of participants, from beginners to seasoned runners, families, and those aiming for specific times, as all distances shorter than the half marathon have no time restrictions. Bibs are collected at the venue, luggage is stored on a communal blue sheet, and the organizers state their commitment to supporting runners throughout the event.
