Sort of a strange thread that you have started. I am a bit confused. Are other posters suppose to chime in on the high mileage tours that they have done as some sort of pissing mach???
Since you are finishing up on a tour, I do not see how you would not know about the factors that make up for average miles per day. I mean there is: A) how hilly. B) what sort of headwind/ tail wind? C) how early did you start D) how many hours willing to spend in the saddle. E) was it torrentialy raining, and after 20 miles you decided to call it a short day? F) did you sleep too close to railroad tracks, got no sleep, today will be short. maybe sprinklers went off, again no sleep. Or a whole bunch of possibilities that make up ones mileage averages. Everyone has their goals, I have lone some high mileage tours, but in the end, I wish that I did less riding, and more rose smelling, if you will.
