Maka Wuhu (known as Wuhu Mountain Loop in Europe and Australia) is the final race track in the Star Cup of Mario Kart 7, which takes place on Wuhu Island. It uses the same theme as the one in Wuhu Loop.
Shortcuts: Maka Wuhu has two shortcuts. The first one is a hidden path in the lake in front of the castle near the end of the second section, while the second one is through said castle. The course also has a rather infamous glitch shortcut, activated by colliding into the walls near the water, or by jumping into the water on the right of the course, right after the second section begins, and teleporting the player to the bottom of the hill before the third section begins. The course has another glitch. It is unknown how to perform this glitch, but if the player falls off the cliff in the cavern after the second section line, Lakitu will drop them in front of the finish line. As of version 1.1, the glitch has been removed from Online Multiplayer, but it still exists in the Single Player and Local Multiplayer modes.
Looks like a cross country rally to me, and it only has a start and finish line. That's why they make it one lap due to the distance.
