I get up whenever I wake up, whether that's by myself or from some noise. I rarely have any "rule", except for rain. When it's raining I avoid getting up as much as possible. Typically I get up, pee, and start water boiling. Then I roll up my sleeping back and pad and get most of my tent stuff packed up. By then water is boiling. I make coffee and oatmeal or whatever is on the menu for breakfast. If it's raining and there is food nearby I may eat out or stop at a grocery store. I get moving in the AM fairly efficiently and normally have a hot breakfast. Boiling water for coffee takes almost no time since I work while the water is boiling.
I rarely have a "lunch". It depends on whether I'm in an area where I can buy food. If I'm strictly camping, my lunch will be the same thing I snack on through the day - granola, nuts, dry fruit, energy bars. Whatever. You will find (most but not all people find) you can't stop mid day for a burger and fries. Long days of riding are all about snacking on balanced food all day. A stop for a huge meal is a disaster for most folks.
When I am in the lower 48 (I'm an Alaskan) I like to stop by about 4PM to make camp, make dinner, clean up, ride locally for fun, read and relax. In Alaska I pay no attention to any of this timing stuff. I ride till 3 AM....make dinner at 5AM...sleep till 3PM...whatever whenever.
The best spot for me is free stealth camping (nothing to it in Alaska, harder Outside) with a nice stream and blueberry patches with soft flat ground. As long as it's quiet and I am alone with no other campers anywhere near me I'm a happy camper. If I'm where other people are, I lock my bike and everything comes inside the tent or in the vestibule. Obviously if I'm hidden away I don't concern myself with that. In that case I probably keep my pannier and all food well away from my tent (bear issues). If there has been any rain on my previous day I clean an oil my chain and drivetrain. Every other day I wash and change my biking shorts. If I know water is a problem tomorrow I'll clean them "today".
