* A, B, C, D, E, F: These letters are often used to mark the starting and ending points of a course, or to indicate specific points where riders need to perform certain maneuvers.
* X, Y, Z: These letters are sometimes used to mark obstacles, such as jumps or poles.
* Numbers: Numbers can also be used to indicate specific markers, especially for larger courses with multiple obstacles.
* Colors: Different colored cones or markers are often used to indicate different areas of the riding school, or to differentiate between obstacles.
It's important to note that the specific letters and markers used can vary greatly depending on the riding school and the lesson being taught.
