The difficulty spike from Peach's Castle to Sunshine Road is rather ridiculous, but fun as it is quite challenging. As you can see at the end of the video, my PB is technically a 52:14, but I got that off-screen months ago before this category even existed so it does not officially count. I still had fun running it and wouldn't mind giving it another go one day in the future.
