I watched Animal Planet's 'Jockeys' and heard somewhere that there's actually a game tied to that horse racing show. I cannot find it anywhere on their site.

There are two places you can go - JOCKEYS : Horse Racing, Thoroughbreds, Racehorses : Animal Planet - on the bottom left of the page you'll find the link to the game, or you can get the same game unbranded to Animal Planet at Horse Racing Simulation, LLC Presents Horse Racing Fantasy interactive 3D Horse Racing Game For Windows. It is a very good game, let alone a horse racing game.
