It's a long ride. At a conversational pace, we took just under 9 1/2 hours including a couple short stops. I would say 9 hours ride time, so that holds pretty well with my estimate of taking a pavement time and multiplying by 1.5. Both of us ride numbers free, so I still don't have an exact mileage count, but I would say the 113 mile map estimate if fairly accurate within a couple miles.
Lastly, we took some photos of the more confusing intersections which will be forthcoming here once Brendan forwards them to me. Thanks go to him for the good company, feedback, and cell phone photography.
