Itabashi City Marathon is the official event brand for a marathon scheduled to take place on March 21, 2027. Its website serves runners, volunteers, and other interested participants by providing information about the event and ways to take part. Visitors can review the race guidelines, learn about the marathon’s features, register, and find course and access details. The site also offers frequently asked questions and contact information to help participants prepare.

For runners aiming to complete their first full marathon, the 2027 event introduced a completion-support entry plan; registration for that plan has since closed. General full-marathon entries and volunteer recruitment are also promoted through event updates. The website publishes registration notices and other announcements, and provides access to information about previous editions, including events from 2023 through 2026. Additional resources include a course image video and a live-stream recording from the 2024 race. Through these services and updates, Itabashi City Marathon supports participation and preparation for its annual running event.
