第4回みなの天空ウルトラマラソン 2026

The Minano Sky Ultra Marathon is an autumn ultramarathon held at Minano Town Hall in Minano, Saitama Prefecture. Participants can select from 35K, 40K, and 75K courses, designed for those seeking a lengthy mountain-town race over a typical road marathon. The "Sky" designation originates from the ascents; after climbing, runners are rewarded with expansive vistas of the surrounding mountains, the town below, and the sky over the Chichibu region. The course begins and concludes at Minano Town Hall, crossing adjacent areas such as Nagatoro, Yorii, Ogano, and Chichibu. While the course is noted for its difficulty, the organizers also emphasize the culinary aspect, with aid stations offering regional tastes. Local engagement is integral to the race's character, aiming to highlight Minano's hills, scenery, food, and community, not solely to track distance.
