In Mario Kart 64, Rainbow Road is hammered by Chain Chomps as they bite the tracks in the opposite direction you are going. In this version, neon portraits of the character are visible all around the course, but that welcomed distraction doesn't pull the player away from the harsh reality that this is well over two kilometers long, and has borders all around the edge, meaning few shortcuts can be taken. One of these shortcuts, however, can be taken by jumping over the borders after coming over a hill. Effective completion can shave a minutes off of the player's lap time. Without it, this track can take almost six minutes. There is also a shortcut at the very end which is really difficult, which is similar to the shortcut in Frappe Snowland at the beginning. What you do is get a Red Shell and hit yourself while you are going fast enough to go past the finish line while falling. You will receive a lap, making Rainbow Road about a minute long or less.
The track returned in Mario Kart 8 and Mario Kart 8 Deluxe and this time, it has three sections instead of three laps, making it much shorter, but it still is by far the longest track in the series. The track has Chain Chomps rolling and bouncing at the same time, causing waves on the track.
