I was a spectator in 2011 but I didnt follow the whole race. I went to the bivouac site for the rest day and setup camp a day before the racers arrived. Then we got up early the day they were to arrive and went out to the end of the special (actual racing) section. It was challenging just to find out where to go. Anyway here's a link to the thread.

I actually got in to the bivouac site at the mid race rest day in 2011. I got there while they were still setting things up and just rode right in. I should have setup camp and stayed. Another guy got in when the racers were arriving he just rode in with one of the racers. But, later when everything was setup, I tried to get back in and was turned away. I said that I wanted to visit the U.S. rider Jonah Street. They said I could have earlier in the day but it was too late.
