Magical Racing Tour is up to 104%, and I still have a little to go. The percentage goes up very slowly at this point (several objectives), while is started with 5-6% per race won.

All that''s left to do is finishing some of the maps while collecting 8 of some random thing. Finish position doesn't matter, but the 8 things spawn sort of randomly (I think it's 1 or 2 on the map at any time on the main track) and one of the maps has a very large split path. That one might require some luck.
