Mario Raceway

In mario Kart 64, this was the "most important" course, which you can see its ghost time in the main menu. There are many interspersed mushrooms which you can bump into accidentally. There are also many sharp curves with surrounding sand so that no one can take shortcuts. There is also a pipe tunnel at the end. Here's a map of the course:
