Jockeys that win fewer than 10% of the time are a bad investment. Those that win at a rate of 10-15% are somewhat better. Jockeys that win at a rate of 15-20% are worth a second look, but jockeys who win at a rate of 20% or above might be like money in the bank under the appropriate circumstances. The average winning percentage of all jockeys is about 40%. However, some jockeys are better than others - in fact, there have been cases where one rider has won more than half of his races over an extended period of time. If you find a jockey with a high winning percentage, he or she is likely being given better horses to ride and may even get paid more because of it. In addition to being able to ride well, there are other factors involved in becoming a successful jockey. You must be willing to put in long hours in the saddle, often riding several races in one day if necessary. It's also important that you don't have any medical issues that would make riding unsafe. With these things considered, a winning percentage between 50-60% is about as high as you can go. If you want to become a jockey, you need to know that this is not a career for everyone. It's an extremely physically demanding job that requires lots of training and practice before you are able to race competitively at the highest levels.
