I have never toured before. Just read a lot of blogs. Usually its people who are a bit more well off than me. The longest ride I did was 145 miles last year. I went from Westbrook, ME to Orono, ME. I did 145 back to back days the first time. The second time I rode up to Orono in a car with my girlfriend because she goes to school up there. Then rode back the next day. That particular ride was my quickest of the three. Took me 10:35 to complete it. I don't plan on covering that much ground on any single day of that tour. And I know it will be a different ball game with the gear I'm carrying.
I hope to carry everything on the back of my bike. Two panniers to carry all my gear except my tent and my sleeping bag. Both of those will be rigged to the top of my Rack. I'll have two large waterbottles and my tools will be in my seat bag under my seat.
