The course
Mostly flat city course starting in front of the Tokyo Metropolitan Government Building in Shinjuku and finishing beside Tokyo Station near the Imperial Palace. Roughly 60 m of total elevation gain, with a gentle downhill opening section; the layout combines a point-to-point trajectory with several out-and-back spurs and turnarounds (around Asakusa, Ginza and Shinagawa). Entirely paved city streets; course has been redesigned in recent years to remove late-race bridge climbs.
