If the system is the same as just plain W3O, you don't even have to get all gold. A mix of different colour medals worked for me, without having to go back and gold every race. I just went through as fast as I could taking the trouble only to win a medal, so I could get all tracks and ships as soon as possible with the least effort possible. Then I just spent my time with my favourite ships on my favourite tracks.
