After a walk break they come back to work on the canter, looking for the adjustability necessary to go from working to collected to medium to extended canters. On the long sides they ride shoulder in and then the half pass.  In the turn back on to the long side Laura asks that the mare stays more straight on the outside shoulder.  In the counter canter they play with positioning and make sure that she doesnt get too low in the bridle to avoid the work. They add a single change when she straighter, and repeat all the exercises the other way.
