For mapping my ride, I used bike route toaster
This let me plan out what I thought I could roughly do in a day, you can select the cycling mode and tell it what speeds you might do. When the route is completed for that day, go to the summary page and have look at course details and even download it to your Garmin GPS, or as a file or view it in Google Earth.
For those that want to know what their expected elevation is during the ride a elevation chart is also provided.
What? you want a cue sheet? well ok then one of these is also provided. (on the cue-sheet page).
