Course intelligence

Know the course before you race it.

Terrain

Flat point-to-point through central Tokyo. Passes the Imperial Palace, Asakusa, and Shinagawa. One of the cleanest, most well-organized marathons in the world.

Conditions

Early March in Tokyo: 38–55°F, low humidity. Cherry blossoms not yet out but spring weather is ideal. Occasionally cold and windy.

Aid Stations

Water and sports drink every 5K. Course provides Vaseline at mile 12. Aid stations operate with precise Japanese efficiency.

Key Challenge

The cold March morning causes athletes to over-bundle and over-drink. Running in 40°F doesn't require the hydration volumes of a summer race — but fueling calories remain the same.
