4th Saikyohei Half Marathon [5km Category • 1 Mile Category] (第4回 佐久平ハーフマラソン【5kmの部・1マイルの部】)

About the Event

Set against the picturesque backdrop of Shimosuwa Town in Nagano Prefecture, the Saku Half Marathon offers runners an unforgettable experience through historic Edo-period townscape and stunning natural landscapes. The race starts just a 5-minute walk from JR Joshin Expressway Saku Station, making it easily accessible for participants.
The course winds its way along scenic routes that showcase the rich cultural heritage of the Nakasendo trail, passing by iconic landmarks such as Mount Asama and the Yatsugatake mountain range. The race also features breathtaking rural vistas, including the lush fields of Kurobe New Field, a testament to Japan's agricultural heartland.
In addition to the challenging terrain and beautiful scenery, this year’s event includes an exciting collaboration with popular manga series "Hokuto no Ken." Racegoers can look forward to engaging with guest runners and participating in special events designed around the theme of the manga.
Entry fees are as follows: 7,500 yen for the half marathon, 4,000 yen for the 5km run (3,000 yen for high school students or younger), and 2,000 yen for the 1-mile race (3,500 yen for family members participating in the same category).
This event promises to be a unique blend of athletic challenge, cultural immersion, and fan engagement, making it an unmissable opportunity for runners and manga enthusiasts alike.
Join us as we celebrate the beauty of Shimosuwa Town through this vibrant race experience.
