FLATWORK BASICS - How to tun correctly in trot
The horse must be balanced with a half halt before the turn.
Keep your rhythm.
Make sure your stride is not too big into the turn otherwise they will be unbalanced.
You need active hind legs, controlling the outside shoulder and riding leg to hand.
Look ahead at the line you wish to ride.
It is helpful to have poles or cones on the ground to create a channel to work with and practice.
You need to be sitting tall, weight equal in your stirrups and do not lean in as you make the turn as this will unbalance the horse.
The first turn is late and the trot is too free so overshot the correct line.
The second turn was tight and was then over corrected so the line was not straight.
The third turn was correct, with the horse being balanced into and out of the turn.
