I have never toured looking for distance. Average has been in the 50 - 60 mile range. Longest day was a just over 120 miles, but it wasn't planned, just seemed to sort of happen. My days tend to go on and on because I stop for everything, roadside markers, every historical landmark, cool diners, good pictures, etc. I usually have a daily goal in terms of a place to camp, but if I don't make, oh well, I'll make it tomorrow. Next summer I want to do a multi-week tour, so I may have to change the way I do things and have mileage goals, or make sure to plan it with a daily average in mind. Bummer.
