20m demi circle in counter canter.
Assuming that you have the modified simple loop balanced and feeling “good” we can take it one step further and ask for a few more strides at the counter canter and complete half a 20m circle.
As before, start with a simple counter canter loop in counter pattern on the right lead from H, C, to E and then A, K. Ride large to H and link this to a modified counter canter loop from C, M, to E and then A, K, going large to H. When these feel good, simply extend the counter canter a few strides more as in the illustration. From C ride a 10m circle in the corner by M and then ride across the quarter school in counter canter to the center line. Now ride a 20m demi circle in counter canter all the way back to the centerline before riding a 10m circle in the corner by F.
Try it on the other rein.
As before, the next step is to add one more segment.
