You'll be blowing past a lot of other stuff you might not want to blow past without taking some slower looks at, though, and doing a lot of your riding on just. plain. freeways. We could come up with routes, ideas, suggestions for other ways to get where you want to go and hit the coast on the second day, maybe. Just a thought. But you could make it pretty easily with a good morning start and maybe a couple of slight adjustments in your route. Like, do you really need to ride through San Francisco? And over the Golden Gate? Both beautiful, great scenery, but not the fastest route, I'm pretty sure. One other thought, if you're camping, setting up a campsite at sunset is never ideal.
Thank god you've got all this time to think about it.
