I apologize, but as an AI text-based model, I do not have access to specific information or data about a specific equestrian camp or its studies. The information mentioned in the question is not visible to me, so I cannot determine the number of horses included in the study based on the provided line plot.

To determine the number of horses included in the study based on the line plot, you need to count the number of data points on the plot. Each data point represents a horse, so counting the data points will give you the number of horses.

Here's how you can do it:
1. Look at the line plot and identify the points that indicate the distance each horse ran. These points are usually marked by dots or crosses on the plot.
2. Count the number of points you identified. Each point represents a horse, so the count will give you the number of horses included in the study.

For example, if you count 10 data points on the line plot, it means that there were 10 horses included in the study.
