Today I did this with my 67.5 gear inch conversion. Total time 7 hours and 22 minutes. I'm not really sure what the moving time was, I stopped for water 7 times, to use the bathroom 4 times, got lost twice and ate McDonald's for lunch. Also had my first experience with hotfoot.

All in all a very good route, the flattest I could put together for this area. I had some issues finding water and ended up using hose spigots from businesses that were closed, as well as getting lucky and finding a hydrant that had accidentally been opened. I felt pretty good, ate enough and rested enough that it was difficult, but not soul-crushing. Thanks to the Octopus for this thread, it really helped a lot.
