Mario Circuit is the first track of the Flower Cup.
The course begins in Toad Town and goes straight for while, then turns left. Then there is a second straightaway near a Chain Chomp. Then there's a underpass and a 90-degree turn. There are many Goombas on the last turn.
- There's a ramp that lets the player avoid the Chain Chomp.
- If the player has a Mushroom, then they can cut off the last corner.
