Part 3: The riders work over a line of fences. Karen has them focus on riding square turns and staying straight on approach and landing. She gives feedback on their position, working on maintaining an elastic arm and utilizing the correct hip angle over the fence. By highlighting the differences between the horses in the group, Karen illustrates how important it is to plan and adjust that plan to the rideability and tendencies of each horse in order to have a clear go. Executing an effective halt after a line of jumps provides a challenge.
