I also run on weekends.
Run 17km Done!
Ginza → Tokyo Station Yaesu Exit (Nihonbashi Sakura Dori) → Bank of Japan → Kudanshita (Chidori-gabuchi) → Yotsuya → Akasaka Mitsuke (Hie Shrine) → Toranomon → Shinbashi → Hibiya Park → Ginza Hanami Run ^ – ^
As the usual course runs in the morning, there are a lot of people because it's a sunny day for cherry blossom viewing.
Ginza was also releasing a pedestrian paradise.
