【横浜】THE CHALLENGE RACE YOKOHAMA 13｜横浜のマラソン大会

THE CHALLENGE RACE YOKOHAMA is a Japan Association of Athletics Federations certified road race held in the Shin-Yokohama area of Yokohama, using the right-bank riverside course along the Tsurumi River. The event is designed around the idea of helping runners challenge themselves and pursue personal records, with a flat, fast riverside setting and an operation focused on performance. The organizer emphasizes a racing environment where participants can concentrate on their goals: pacer groups are arranged for a wide range of target finishes, aid stations are placed around the loop, and runners are able to warm up until shortly before lining up. The course is shared with the public riverside area, so the event also highlights safety rules such as controlled running formation, attention to narrow sections, and restrictions on actions that could interfere with other participants or general users. The race is connected with several broader running programs and rankings, including R.LEAGUE, TEAM ONE TOKYO, the All-Japan Marathon Ranking, and the half marathon single-age ranking. Organized by RDC RUN CLUB and led by race director Yuki Yagi, it reflects the group’s aim to create accessible, memorable races where citizen runners and competitive runners alike can test their training in a certified race environment.
