I did the Mexico to Canada ride several years ago and it was a great experience. I want to do it again this year with my son and the guys that run it are a few people short on making it happen. If you ever thought about doing it now is the time, not sure how many more years they will be doing it.
They run 2 routes most days with a hard way for the more advanced riders and easy way for the larger adventure style bikes.
Don't go on it expecting a lot of single track tight stuff its not that kind of ride as there is no way they could cover that kind of mileage in the tight stuff. Its a good mix of everything with minimal paved roads. I would be happy to answer any questions or you can check out there website and contact them at:
