I'm one of those who love chocobo racing, for me it is the most fun activity that the GS offers. I got really into it and have raced, leveled, retired, and bred over a dozen birds. My current bird has over three hundred wins at max level alone. But, the problem is, racing (and the majority of the GS in general) has not gotten any attention for a very long time. It's the same three tracks against the same pool of 10 to 15 NPC birds over and over and over again. If I am lucky enough to encounter another player (a rare thing on it's own,) when they move into my bracket, they are at the very bottom of it and stand very little chance against me and my high-end bird. After I completely blow them away two or three times, they usually give up and don't queue anymore. Then it's back to grinding the same NPCs again. I would absolutely be over the moon if SE showed some love (anything really, new tracks, let us queue via DF, etc) to racing.

Starting out, you are going to have a lot of fun. The track obstacles will constantly change and you will be against a plethora of different NPCs (and, if you get lucky, the occasional player) as you move through the different brackets and breeding your retired birds is fairly rewarding on its own. If you managed to make it all the way to the very top of the food chain though, it will get stale after a while. It's one of those things that you have to enjoy the journey of, not just rush, rush, rush straight to the end.
