Slide Coliseum is the 17th track in Crash Team Racing. It is located in Gem Stone Valley, near the passage to N. Sanity Beach, next to Turbo Track. It is a bonus track unlocked by earning 10 Relics of any color. It has only a Relic Race available on adventure mode and also features in the Crash Cup in arcade mode. It is also the only race track with no turbos at all. Some people believe that it is the easiest Platinum Relic to obtain in the game.
Interestingly, both this track as well as the Turbo Track share the same background music as Tiny Arena.
Note: If playing against Oxide's Ghost during Time Trial Mode, the ghost will use the terrain near certain spare tire sections as ramps. This is only easily utilized if the player begins and maintains boosted speed.
