About the Itabashi City Marathon
The municipal marathon draws thousands to Tokyo's northern river corridor. Its simple event base and broad time allowance make it accessible, while the exposed course adds its own difficulty.
Course
The certified out-and-back route follows the Arakawa riverbank from Itabashi. Elevation is minimal, but wind, long straight sections, and limited visual variety test patience.
Race-day weather
Mid-March is often cool, though the river corridor can be windy and exposed. Rain or an unexpectedly warm afternoon can change the return leg considerably.
