Okay, so I am riding in a show in a couple of weeks, and I am planning on doing training level test 4- it is suggested that we go down a level because since I am riding one of the lesson horses, and you don't know who you are going to ride until the day of the show. Anyway, I am going to do training level 4, and it all looks pretty simple except for the 'one loop' that comes up occasionally. Can someone explain to me what this is exactly? It would really help me out. Thanks in advance!
