That would be rather a spectacular sight to see if that happened. The horseless jockey might not officially win the race but I think he or she would be pretty famous. Beating the horses after being thrown off! Now that would be a sight to behold.
They would have to do something for that jockey. Maybe a trophy and a lifetime membership to a Spin Class club.

What are you smoking?
Same thing, a jockey without a horse or a horse without a jockey would be disqualified. But if a jockey did do that, all horses would become dog food and the jockey would become an Olympic star.
