Story Mode: Chapter 9
Mission 9, the last chapter of story mode, takes place here and just like its Grand-Prix counterpart it is extremely challenging. with no walls or hazards (Other than falling off the course) it is impossible to run out of boost here and die.

- It is worth noting the fact that Phantom Road is quite literally the F-Zero counterpart to Rainbow Road from the Mario Kart franchise (which, interestingly enough, actually appeared in F-Zero X for the Nintendo 64).
- Phantom Road is actually a toned down Rainbow Road, seen within the Data of F-Zero AX. This is due to Rainbow Road originally having fast moving bright colors all around the Track(s) which likely would have led to possible seizures. Because of the toned down colors and speed thereof, the name Phantom Road was eventually adopted.
