Is it possible to do the race with friends?

Yes, it is possible to participate in the adventure with friends.
To do so, each participant must register individually (1 participant = 1 unique account).
If you want to share a room with your friends, you will have to enter their names in the "hotel" section when you register.
If you want to be in the same cell at the bivouac, you will also have to fill in the names of your friends when you register, in the "bivouac" section.
