I wouldn't use google to plot the route, it's cycle routing is eccentric. For a ride like this you carefully plan to route ahead of time, you don't just except what google comes up with on the day.What about Google Maps on your phone? My cycling pal used it to ride from Lancashire to Cornwall and back for a wedding. In cycle mode it took him along some super routes. Just turn off the screen and plug in an earphone.
I've just asked mine for a route from my office here to the Arc de Triomphe and it calculated in a couple of seconds. Perfect.
(every time I've used google cycling routes, I've regretted it, so I haven't used it for a while).
