【東京荒川】THE CHALLENGE RACE 37｜日本陸連公認レース

THE CHALLENGE RACE is a JAAF-certified road race staged on the Arakawa riverbed, starting and finishing in front of Arakawa Todabashi Green Space Athletics Stadium in Itabashi, Tokyo. The event is built around a fast riverside course on one of the flattest sections of the Arakawa area, making it especially suitable for runners aiming for personal bests or qualification standards. Its format emphasizes practical support for performance: pacers are assigned across a wide range of target groups, helping everyone from newer runners to highly competitive athletes maintain an appropriate rhythm. The race also highlights an efficient pre-start flow, with assembly close to start time so participants can continue warming up until shortly before racing. On-course support includes hydration and food service, and race-day operations cover bib pickup at reception, result publication, and finisher certificate options. The event is also connected with broader marathon programs and partner races, reflecting its focus on serious road-racing goals while remaining accessible to a broad field of participants.
