いばらきチャレンジマラソン２０２６IN水戸信用金庫スタジアム 2026

Ibaraki Challenge Marathon is a Sunday morning running event based at Mito Shinkin Bank Stadium in Kasamatsu Sports Park, with the first start listed for 8:30. It is set up as an open participation marathon event: Ibaraki residents can enter, but the listing also invites people from outside the prefecture, and the age range runs from children through adults. The available information points more to a stadium-centered meet than a detailed road-course marathon, since the venue is the stadium itself and no wider route is described. Junior high school students and older runners can enter more than one race category without paying an extra participation fee, which makes it useful for people who want to try multiple distances or events on the same morning.
