This category is inspired by Jopes. He created it in a video 4 months ago, but did not create any concrete rules for it. So I took it into my own hands.

Jopes video:

You play all 8 tracks from Mario Kart 8 Deluxe + Booster Course, which have “Circuit” in their name.

Mario Circuit [Wii U], Mario Circuit [GBA], Yoshi Circuit, Hyrule Circuit, Toad Circuit, Mario Circuit 3 [SNES], Mario Circuit [DS], Daisy Circuit

Everyone is free to decide the order for themselves, so there is plenty of scope to find the fastest order.

The run is played in Versus Mode, with a similar ruleset to the 48 and 96 tracks run, but with the difference that the courses are set to Choose and the race count to 8 tracks. You could also consider introducing subcategories for 200cc, 150cc, Items and NoItems as in the regular MK8DX run. The timer starts when you press A at the OK button and ends when you cross the finish line in course 8.

Here is a recording of me driving the Circuit%. I play 200cc NoItems there.
