第17回 荒川ハーフマラソン＆30km

The Arakawa Half Marathon & 30km is a running event based at Horikiri Mizube Park in Katsushika, Tokyo, using the Arakawa riverside area as its course setting. The event emphasizes strong value while still offering services such as chip timing, a live results website, and web-based finisher certificates for participants. The course is described as mostly flat, with an asphalt surface and a few rises and dips under elevated structures. Because it is a lap-style riverside course, runners regularly pass one another, creating a less isolated race environment typical of urban riverbank events in Tokyo. The organizer highlights several features intended to support runners, including accurate timing technology, quick access to lap and finish information, guest encouragement, and support from BOOST Pacers. The pacer team is presented as part of the organizer’s broader effort to provide runners with opportunities to race and pursue personal goals, though pacer placement may vary on the day. The event also notes participant benefits connected with online yoga lessons, positioned as a way to support post-race recovery and future conditioning. The course is not fully closed to the public, so runners are asked to share the route with general pedestrians and other river users while participating safely.
