Sand Ruins

Sand Ruins is the last EX Grand Prix course, but unexpectedly not the last racing course in Sonic Riders. The last course turned out being Babylon Garden due to the cause of Jet using the "key" to access the giant garden floating in the air.

Overview
In story mode, Sonic is the only playable character, but in a normal race, every character is valid. The course takes place at daytime, in a desert. The start/finish line is in a colosseum, surrounded by people watching. There are many ruins throughout the course, some of them being obstacles that can be hit by a power-type character, or must be avoided any other character that's not strong enough to break through.

There is also another version of this track in the unlockable Babylon story, only playable as Jet the Hawk in the Babylon Story Mode. This track is called Dark Desert.
