第97回・赤羽トライアル（5km/10km/15km/HALF30km/フル） 2026

From Akabane Station or Akabane-Iwabuchi Station, this event leads to the Arakawa Riverbed Course: straightforward, open, and flat. The 97th Akabane Trial feels like a regular runner’s meetup rather than a formal competition, with beginners and fun-run participants explicitly receiving a "big, big welcome." The course uses a short flat loop, making it easy to find your rhythm, monitor your effort, and avoid overthinking the day. Anticipate riverbed running, not a grand spectacle, along with the practical quirks that make this series beneficial: a "stamp card gift" offering a free race after three stamps, and the nearby public bath Otamayu available for participants afterward.
