But each racehorse has an entire village behind it, and many of the people who help get a racehorse to the winner’s circle have become stars in their own right. Passionate and driven jockeys, cerebral and clever trainers, brash and colorful owners; horse racing has an embarrassment of riches when it comes to big personalities.
