Near the finish
Marunouchi and Tokyo Station
Why: You walk back to your room after 42 km instead of riding a train. The Imperial Palace loop is a few minutes away for the easy runs beforehand, with running stations nearby for lockers and showers.
The catch: Race morning means a train to Shinjuku at the same time as everyone else heading to the start. The JR Chuo Line runs direct from Tokyo Station, so it is one train, not a transfer.
