Here is a great barrel racing drill or exercise to remind your horse to stay locked on a turn and not to leave it too soon.
What you will do is circle the barrel twice (and sometimes more if necessary to get it right) before moving on to the next barrel. Remember to properly prepare your barrel racing horse for the turn (with two hands if you would like), then ask for the turn. Make a perfect circle around the barrel with four wheel drive forward motion. Your horse should be moving forward in a controlled fashion arced/bent around the barrel soft in the mouth and body.
You can do this at a walk, trot and lope as long as you are working at a controlled speed. You can use one or two hands on the rein depending on your horses level of training and your comfort level. Its good to practice with one hand around the barrel since that’s how you are in competition (when the other is on the horn). Remember to use your legs to help position and guide him as well. Your inside leg will help get bend and keep him from coming in too tight. Your outside leg should be keeping the hip in and stopping him from drifting out or going wider than you’d like.
This drill is great for the horse that bows out and off of first, goes wide off of second and/or blows out of third. It will emphasize that you want them to finish the turn before you more onto the next barrel. Remember to do this only at a speed it can be done correctly and with control before moving on to a fast speed.
