How do I do this?

[Chiramu]

I've tried chocobo racing, but I always wind up coming in... not the top three and earning ~30-40 MPG for a sizable time investment.

I'd agree about it being fun, but the whole thing seems to control very clunky.

Even if you come lower than top three it is still only a flat investment of 10 mgp, it will always be a increase unlike Triple Triad where the match fee goes up and up depending on the difficulty of the opponent . I feel chocobo racing tends to earn you more mgp because of this.
