When analysing 10-year trends in horse racing, you’re looking for long-term patterns that can help you identify which horses are more likely to perform well in the future. To do this, you would want to track the results of the winners and placed horses in races over the past 10 years.

For example, you might look at the records of certain trainers or jockeys who have consistently produced winners or placed horses in races over the past decade. You could also analyse the performance of particular breeds or bloodlines that have a history of success over the long term.

Another useful approach is to analyse how horses have performed on specific tracks or under certain weather conditions. For instance, if you notice that certain horses have consistently performed well in races held on a particular track, you might consider those horses as strong contenders in future races held on the same track.

Overall, the key is to identify consistent patterns over the long term, which can help you make more informed decisions when it comes to betting on horse racing. By noting the performance of both winners and placed horses over a 10-year period, you can get a more complete picture of which horses, trainers, jockeys, and conditions are likely to lead to success in the future.
