There's also an 11-hill extended version (Distance: 73 miles. Climbing Elevation: 5,659.2' Maximum Elevation: 636.5' Minimum Elevation: 23.8')
Here is a site that has the waterworks route. Took somewhat longer than I expected to write it up. I have not done a route guide before.
Maybe I'll see you on the 7 hills of Kirkland ride next week. I haven't picked a distance yet, but I'm also considering the century.

I'll be on
this.
