# Horse Racing
The horse racing tournaments are organized into stages. In order to retrieve all the available stages for horse racing, it is necessary to filter by sport id, 55, in the "All tournaments by sport" end point.
The answer of the end point (follows) will list all the stages available, 3 in this case.
```xml
```
To get more detailed info related to the horse racing stages it is possible to filter again using the staging id and another different end point.
For example it would be possible to use the "Schedule for a tournament" end point with the stage 697750 (second in the list above).
The result is the following which shows the list of the stages related to the one we have used to filter.
