Well first off i noticed that most of the races are really high level and really low level.  Which means you did not set the "required_level" for any of them.  Some races have "allow_only" set to steam ids already which could also be a problem if its not your steam id.  I also just happened to notice that the last race ends with "{" and it should be "}". Just for starters. There are probably way more problems than that but lets start there. Explain yourself
