What I planned to do was get a general route from the suggestions. Look at it on the printed maps and then put it in to Tyre. Tyre is like Google Maps in that it let's you drag and change routes, etc. It also will export a GPX file which I could upload as a route to my Garmin Edge. It also lets me share the GPX file in case I want to send it to anyone for a sanity check.
Oh, planned date is probably end of June.
