第43回大町アルプスマラソン 2026

The Omachi Alps Marathon takes place in autumn in Shinano Omachi, Nagano. Runners can view the Northern Alps ridgeline during the race. The event's theme, “Let’s run on the roof of Japan,” reflects the city's high mountain surroundings. The course winds through various parts of Omachi, transitioning from mountain bases to farmland and lakeside areas. This event has been held annually since 1983. It holds local significance as Shinano Omachi was the first location in Nagano Prefecture to organize a full marathon for general participants.
