I actually rode further than I had planned so that's a plus. My wife enticed me to ride further to get some food for lunch and I agreed.
You're riding like I like to tour -- ride in the morning and stop for the day in the early afternoon. That give you plenty of time to 'recharge' the old body while you take in the sights/museums/good local food/whathaveyou at your destination in the afternoon/evening.
The tour I have been planning is 'only' 1037 miles, but I plan to do it in three weeks, riding 40-60 miles/day and taking a couple of non-riding days. Stopping for the day around noon in a small town so I have plenty of time to take in the local 'color'.
Keep the updates coming!!!
