【横浜】THE CHALLENGE RACE YOKOHAMA 12｜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 along the Tsurumi River. The event is built around helping runners pursue personal bests and compete in a focused race environment. Its riverbank course is described by the organizer as a fast, low-profile route suited to record attempts, and the race places pacers across a wide range of target times to support runners aiming for specific goals. Aid stations are prepared with drinks and energy support, and the operating format allows participants to warm up close to the start, helping them arrive at the line ready to race. The event is organized by RDC RUN CLUB and reflects the race director's stated aim of creating accessible but serious opportunities for runners to test their training. It is also connected with several recognized running programs and rankings, including R.LEAGUE qualifying, TEAM ONE TOKYO, the All-Japan Marathon Ranking, and the age-ranked half marathon ranking. The venue uses the Tsurumi River right-bank marathon loop course, with reception around Shin-Yokohama 3-chome Park, making it a compact urban race setting in Yokohama with a strong emphasis on performance, organization, and runner support.
