Hej,
I did the rally in 2006. A lot was lost to us due to the language barrier. The provided interpreters were horrible. So we missed lots of updates and route changes.
The food was descent but I would recomend to bring more food that you would eat for breakfast. Unless you like eating just rice and a few others things put in. I think they were meat like objects
.
Obviously bring the usual energy bars and energy powders.
The road book was in English and French with horrible drawings. So navigation is "normal".
I think I would just rent a bike there instead of shipping your bike over. I sent mine over and the cost was very expensive for the shipping to and from.
The terrain was breathtaking and the course not very difficult.
Lycka till, hej da.
