When you are traveling long distances for a sight seeing trip (over 1000 miles), how many hours do you normally spend on the bike each day? Is it smart to plan on a mandatory 8 hours of riding each day, or is it better to plan on 4 hours a day and if you feel like riding more go for it? I plan on taking a couple of weeks of vacation to go riding in the near future and I am just wondering how far should I plan on traveling each day without getting so fatigued that the trip is no longer much fun. It seems that most of the long distance threads that I read start off with the rider going many miles on the first couple of days, recovering for a couple of days, and then hammering out a bunch more miles before resting again. I love riding and look forward to many miles in the saddle, but I don't want it to start feeling like a chore.
