This is a video of Sherry Cervi racing. She is a pro barrel racer and watch the way she makes pockets around her barrels. Especially on the last barrel. She goes out around the barrel a little bit and then really close. It was easier to show you a video that try to explain it. Also, make sure you are on the correct lead that really makes a difference on the way they turn their barrel. Once you turn each barrel you need to be looking at the next barrel because that sets your body up for the next barrel. One last thing, when you're training him to run barrels do everything at a walk and trot before lope. I had a trainer that said if you learn slow and get it right, you'll do much better going fast.
