Total was 90km. It was a mostly straight shot from west edge of tokyo to the east edge passing through central tokyo. It's one of many routes and I only saw a small slice of it. It's a bit of a labyrinth at times if you don't stick to the main roads. I hit a lot of roadblocks and winding paths through residential areas. I didn't want to overplan though. Getting lost was part of the goal. All I knew was that I had to head east.
