11th Mandarin Relay Marathon ~Great East Japan Earthquake Recovery Charity~ (第11回 みかんリレーマラソン～震災復興チャリティ～)

Join us on December 20, 2026, for the eleventh edition of our beloved race at AGF Field. Located just a short 30-minute train ride from Shinjuku via Keio Line and a relaxing five-minute walk from Hidaka-go Station, this event offers exceptional accessibility.
We're excited to offer two engaging relay categories: the one-hour Family Relay with divisions for families, elementary school students, teams of friends, and an open category welcoming participants aged 5 and up. Additionally, there's the free "Errand Run" designed specifically for young children accompanying their family members in other race categories.
The three-hour team relay is another highlight, perfect for those looking to challenge themselves over a longer distance while fostering teamwork and camaraderie among runners.
One of our most cherished traditions returns this year with a costume contest, where participants can unleash their creativity through elaborate outfits, much to the delight of both runners and staff alike.
In support of Japan's ongoing recovery efforts from the Great East Japan Earthquake, we're also proud to contribute 100 yen for every participant towards rebuilding communities in affected areas.
Come join us this winter for a day filled with fun, community spirit, and delicious oranges awaiting all who cross the finish line!
