71, hope to make 83. DW and I still tour. Camping is now behind us and kids inheritance pays for lodging. (Thanks kids). During our Europe tours a few years ago, the trains were our friend in hilly areas. Do not hesitate to make them part of your travel plans. Also, distance/rest days can be altered since the boss does not care when you return to work. Trains can make this work too.

Definitely have the most comfortable set up. Perhaps consider an e-bike. And know that a 50 mile bike ride where you still feel ok at the end is better than 500 miles that is followed by an uncomfortable recovery. You give me inspiration. Thanks for posting.
