This minigame plays identically to the gameplay of both Action Race and Quick Race: the two players each control a team to race against each other to the Goal Ring. Obviously, the team that reaches the Goal Ring wins. However, these stages are designed in a way that the stage length is long as implied by Omochao's description. When playing through all the stages, the player whose team wins two out of the three races wins the entire minigame.
The following stages played in Expert Race (in order) are brief sections from their respective single-player mode, much like with the stages played in Action Race:
When the player selects "ALL", the game will go through all three of the stages mentioned. The player who wins at least two out of three stages wins the entire minigame.
