Well, I admit that I'm not speaking from specific, personal experience, but maybe a little more from logical deduction.
(You don't need to answer these; they are rhetorical questions for you to consider.)
1) How long have you been riding motorcycles, i.e. what's your experience level, generally?
2) Have you taken 8 to 10 hour day trips before? 3 day trips?
Reason I ask #1 & #2 is that if you haven't done either, don't try this when you have a fixed arrival time that you need to make for business. The reason I also ask #2, is that if you haven't done this previously, you may not be adequately prepared. Do you have a good tool kit mounted, and know how to use it? Tire repair kit & pump? What do you carry for safety and sustenance (i.e. adequate water, some hiking shoes in case you have to hoof it 20 miles for assistance)? Back to #1 & 2: How to you handle a 10 hour riding day, physically? No back issues, great health in general, and so forth?
I also agree with those suggesting adding in extra days & slack time. If I'm riding cross country to an important business meeting, I am AT MINIMUM arriving Friday mid-day, for a Monday morning meeting. You'll probably need a day or two to rest and get your bearings, even if the ride goes smoothly. What's your back-up plan in case of a break down? Tow insurance? Where's the closest dealer? If you break down in Colorado, tow it to a dealer, leave it, maybe for weeks or months if parts are unavailable, do you hop a plane and rent a car in Orange County to make your meeting? That's the kind of contingency backup plan I'm talking about.
What if you hit a storm track? Just keep going through the storm? Through the Rockies, too? Or, do you take a day or three off and sit it out in a motel? What happens to your perfectly planned schedule then?
Do you know what
"Spot" is? You're gonna want something like that if you end up down a gully wrecked and immobilized. If you survive and DON'T have one, you're wife is gonna kill you for leaving her in fear for hours, days, maybe .... way longer, until help finds you ... if it does.
I'm tentatively planning much the same kind of thing, but going south from Idaho to California (N to S), then Eastward. The optimum time for such a trip across the Southwest to Southeast is ... well, sometime between now and summer. I won't be ready by then, so that trip may have to happen 2024. If I'm crossing the country during Summer to Fall, I would plan a more Northerly route.
My point is that while I might do the same thing you're doing, I'm planning it pretty far in advance, I plan to take a series of 2 hour, half day, full day, and overnight trips, adjusting my load out along the way, as well as conditioning my body. I KNOW that I'm not ready, and I'm pretty certain that I know how to get ready, logistically as well as physically.
There are PLENTY of riders on this forum and others, lol, particularly the younger folks, who'd take your trip at the drop of a hat. (In fact, I have a friend my age (67 yrs old) in Southern California, had he read this post, who'd be calling me and telling me that he was about to come up to Idaho and stage an intervention, i.e. that I needed a testosterone transplant for being such a wuss.) To each his own ...
... which should be your primary consideration. You do you. Have a great trip!
