10/10(土)：ロケットマラソン2026東京大会【5km・10km・ハーフ】

The Rocket Marathon Tokyo is an autumn running event in Katsushika Ward, Tokyo, offering 5 km, 10 km, and half marathon distances. It is part of the Rocket Marathon series, which includes an Osaka event later in the month. Runners can choose between a short race, a 10 km effort, or a half marathon as the marathon season begins. The Osaka event exemplifies the series' style: races use chip timing, accommodate beginners to advanced runners, and limit entries to hundreds, not thousands. The Osaka course is located at Yodo River Park’s Nishinakajima District Baseball Field. A past review noted gentle inclines and declines, smooth race-day operations, and ample staff. Elementary school students may enter the 5 km and 10 km races; the half marathon is open to participants from junior high school age.
