Some of these times are getting faster and faster! Especially the Vanilla Lake 2 time! All of my time trials were done using Mario. New course records are in blue.

Remember, these runs were made by my favorite karter, Mario.

* The Vanilla Lake 2 times were achieved by going around the track, not by skipping laps with Lakitu. A fast time like this can be achieved by cutting corners. I have found that skimming slows you down, even if the the engine does not. Try not to touch the snow, either. And don't lift your foot off of the accelerator!
