Course
The half starts on the Kawagoe-Ageo road and follows an out-and-back route through Ageo's town center and greener outskirts before finishing inside Ageo Sports Park Athletic Stadium. With little rise and fall it is built for fast times, and the course carries World Athletics and JAAF certification.
Race-day weather
Late November in Saitama is typically cool and dry, close to ideal half marathon weather. Morning starts can be chilly, so plan for a warm layer before the gun.
About the race
Ageo's November half draws many of the university teams that contest the Hakone Ekiden, so public runners get to see Japan's top collegiate runners up close. The public field is capped at 5,500, and the top two Japanese university men earn a trip to the NYC Half. It is also a RUN as ONE partner race for Tokyo Marathon 2028.
