These are links to the ridewithgps.com link to each of the routes.
I have also included the GPX file as well.
If you don't use the GPX file, you will have to log into ridewithgps to download the file to your device.

It appears that the GPX routes look a little short. They are giving you straight line routes where there are winding roads. Please make adjustments to your route, or download the file from ridewithgps.
The roads are well marked.
