Hyrule Circuit is the last track found in the Triforce Cup DLC in Mario Kart 8.
Mario Kart 8
The track takes place in the Hyrule Castle and some surrounding places, and inside of the castle itself. On the inside of the castle, there are three small pillars with rupees on top of them. Hitting these three pillars not only gives a speed boost, but reveals the Master Sword, and a jump over it. Also, like Waluigi Pinball and Mute City, some certain sounds were changed to Zelda music. Such as when a player gets an item, the music for whenever Link opens a chest plays. Also, rupees replace coins, and Deku Babas and Keese replace Piranha Plants.
