東京都北区赤羽マラソン - 21.097km／10.548km／5.274km／ハーフリレー - 2026

Along the Arakawa riverbed in Akabane, this feels like a proper local runner’s morning rather than a big show. The spirit is simple and neighborly: a hometown marathon where adults, kids, solo runners, and groups can all line up without much fuss. It is the kind of event where the race is only part of the outing, because the shopping streets are waiting after the run. Expect a flat riverbank course with chip timing and an immediately issued finisher certificate, which is always nice when you want to check how the legs really behaved. The crowd should be a mix of regular runners, families, and groups taking it at their own pace. The charming local touch is the raffle prizes from Akabane, a small post-race quirk that makes the event feel tied to the neighborhood.
