Harness racing is one of the two main types of horse racing. The other involves saddles, jockeys, and powerful thoroughbred horses. Conversely, harness racing involves a more durable horse, driver, and a two-wheeled vehicle, known as a sulky. It is seen in 30 countries by millions of adoring fans, who wager billions annually. The horses reach 30 mph, even with a driver in tow. These drivers, not to be confused with thoroughbred riders, sit low on the seat of the sulky. They race around a track, just as they do in standard thoroughbred racing. Yet, you will notice that the horses run in a peculiar way. That’s because the horses must run at a trot or pace, depending on the race.
