"Trace du Hourra" is French for "Trail of Hurray".
The story is set during the stone age before man walked on two feet. One day a caveman learns to walk on two feet and excitedly runs down a hill shouting "Hourra" (Hurray) to tell his friends of his discovery.
The roller coasters' course is the path of the caveman as he weaves between rocks. The track is painted brown to represent the trail.
This unique theme is the reason the Trace du Hourra is not painted white with a bobsled theme as all other bobsled roller coasters are.
