if your bad like me u cant get first through the whole races my quwstion is do u have to win the races also im new to speedrunning this game

As far as I know the only thing you have to to is finish the set tracks for the category. Placement doesn't matter.

Ayden is correct, there is no requirement to win all the races, it's just about completing all the tracks in the category as fast as possible.

oh OK thanks my first run was bad so that's why I wanted to know if u did or not have to be first but I will get better :)
