第115回・季節の荒川ハーフマラソン 2026

The Arakawa setup is practical: close to the station, located under the elevated tracks, and sheltered enough that “rain cover is OK.” This is the 115th running, giving it the feel of a steady local series rather than a large-scale production. The pitch is simple: “at a reasonable price,” with “a wide range of events” and a completely flat course. Expect straightforward running on a flat route by the river, the kind where pacing matters more than hill strength. The field is split into 10-year age divisions, keeping the racing honest for those who like comparing themselves with runners in the same bracket. Win your division and receive an invitation to run the next race free; point cards are also issued, and collecting three allows entry into an event of your choice.
