 The ultimate horseman's challenge is right off of the EXCA, the Extreme Cowboy Racing Association. We like to pride ourselves in horsemanship, the ultimate horseman's challenge. That's why we use it that. It's basically the same as the EXCA, but we have our own governing body and our own rules. We are co-sanctioned with them, so to say, because we can run our UHCA and gain points.
