We were at Charelvoix last year. No stage notes(like the US) available for teams that didn't do recce. Route book was very skeletal. If you want to drive the event completely blind, you can, but three days of driving like that obviously puts you at a huge disadvantage.
Sometimes you can purchase notes from other teams. We were given notes by other teams, but most of the stages were run in reverse with different start control locations, making it extremely difficult to extrapolate the information.
I've just spent the weekend with my codriver and a Talon on stage roads around New Hampshire changing my pace note system from the old UK numeric system to the Jemba system. In fact we took a couple of roads that we had Jemba for and before seeing them we made our notes and they were very very close which surprised me more than anyone.
So if there's sufficient interest we will copy and sell our Charlevoix notes this year (as well as Defi ones, which we will now make on the Jemba pattern). Marc is going to covert all my old notes for Charlevoix to the Jemba numbering system, and then will do the recce to refine them.
