1200km/day! You can do it.
3 days of 800km would be better unless your used to looooong days. When doing days of that length I like to leave very early, 5:30 am, give or take. Get on the road early, beat the heat of the day and beat busy traffic if it is a weekday and you are in a heavily populated area. You can cover a lot of ground by noon as long as you can keep going without stopping saving for fuel. I would stop riding around 3 pm, maybe earlier depending on the distance made. You do go a good distance in a day, are able to stop early, can relax, get a good meal and get a good nights sleep to repeat the next day.
Thank you for the replies.
I will be going on a Ducati Monster 620, so it should be fairly comfortable. The only long distance touring I've done is ~800 km toronto to NYC on a Ninja 250r:lmao:. I regularly do ~600km days around Ontario
I think you guys are right - 2 days of 1200 km each is pretty ambitious. I am going to do a day trip of Toronto - Montreal - Toronto some time this week. It should give me a better sense of what "1000 km/day" feels like. If Denver ends up being too far, I may stick with the Tail of the Dragon (about half the distance away as Denver).
