About the Event

Test your speed on a flat, fast loop course in the heart of Tokyo at the **Tokyo Challenge Marathon 2026 on Sunday, January 25, 2026**. This popular event, starting at 10:00 AM from Rainbow Square in Adachi Ward, offers both a full marathon and a half marathon run simultaneously on a course designed for personal bests. With a strict capacity of 1,000 full marathon and 300 half marathon runners, and online-only registration via Runnet from August 1 to December 14, 2025, securing a spot in this competitive race requires early planning.

A unique feature of this event is the "Target Time" prize category for the full marathon, where runners can declare a goal time upon entry for a chance to win additional awards. Every finisher receives a commemorative towel and drink, and athlete bibs are mailed in advance for a smooth race day experience. Whether you're aiming for a podium spot in your age group or chasing a specific time goal, the Tokyo Challenge Marathon provides a professional, well-organized platform for a serious early-season race in Japan's capital.
