Hi Richard!
Thanks for letting us know about the wonderful adventure ahead of you; very best of luck and all good wishes your way.
Since your route will be going near, to, or through areas I am very bicycle-familiar with, I can advise or offer suggestions to help answer any questions you might have. Please feel free to contact me, and I will do what I can. I have looked at your map and it is very nicely done, but a little small to see all the finer details of your route.
I'll be following every roll of your wheels!
All the best,
Dan.
