Owning and training a racehorse is a rewarding pastime, especially if you make it to the competitive circuit. Unfortunately, it costs over $10,000 to train a horse for racing, excluding other fees and ownership costs.[1] Racehorses need to be young and fit to race, so it’s important to start training when the horse is around 1 year old. If you feel confident in your horseback riding and handling skills, you might have success in your journey as a racehorse trainer!
