Do the horse bet systems work and can you make money using them? Horse bet systems should first be defined.
A system is something that tells you what horse to bet on and in which races. It sure sounds great but the problem is that most horse bet systems are not very good in the long run.
A big problem is that there are many horse bet systems. If horse racing systems worked then people would be winning money consistently as they bet on horses. A horse racing betting system tells you how to correctly bet on horses that should win. The best way to tell if a betting system is any good is by its results. The problem with using a horse bet system is that you are often going with trial and error. You either have to test out the system by tracking it or you do it with real money. Unfortunately you cannot be sure when you have a system that it is going to be reliable as you bet on horses.
All you can do with a horse bet system is to try it out either by tracking it or by playing it. And even if you find the system has worked for a short period of time that does not mean it will work in the future. You might find that someone has a system of picking horse winners that identifies winners in a 2 yr old race that fits a certain criteria. The problem is that the criteria may not always be the same. And it also could be the system is not time tested. If you look at horse racing betting systems from a sports betting perspective you should know that unless there are 1,000 races it is not time tested enough. That is a lot of races. Sports betting systems that are any good usually have been tested over time, and most fail that test, just as horse racing betting systems do.
