What is the difference between mini prix and jumper derby?

A mini prix is a competitive show jumping event typically featuring a set height and course designed to challenge riders and horses, often serving as a stepping stone to larger competitions. In contrast, a jumper derby combines elements of traditional show jumping with cross-country obstacles, requiring horse and rider to navigate a varied course that may include natural fences. While both events assess jumping ability, the mini prix focuses solely on show jumping, whereas the jumper derby emphasizes versatility and adaptability over varied terrain.
