I've been avidly thinking about my upcoming 400 mile self-sustained tour since 2012. It wasn't until this past winter when I decided to discover Google's bike route mapping. If it was just me, I would just put in an address to start and finish and just ride 80-100 miles a day, find a bush or something to camp behind off the trail when I got tired. If I got lost along the way, so be it. But since I'm riding with a 10 year old I decided I better put more thought in the mapping out the route.
Due to the nature of our bikes and the safety of the kid, we're going to stick exclusively to the trail when possible. We also plan on riding no more than 60 miles a day because she wants to see things along the way (museums, etc.). I was going to do this as well but I would do it at a faster pace (20 minutes instead of an hour in one place) plus the necessary looking up and making reservations for conveniently located campgrounds along the way.
So I ask, is it normal to plan extensively and cautiously for a first tour?
