Challenge Mode tasks players with completing specific objectives, such as clearing a course without touching a single coin or touching the ground. There are four single-player Challenge categories: Time Attack, Coin Collection, 1-Up Rally and Special (miscellaneous challenges). Boost Mode Challenges require two players, with one player using the Wii U GamePad controller and the other using a Wii Remote controller. Once players complete a Challenge, the game saves a replay of the action so players can show off their accomplishments.
