Western horsemanship is a pattern class. You are judged on your equitation and the willingness of your horse, as well as how well you perform the manuevers.
This year our pattern consists of a lead departure, a small collected left circle, lead changes, large serpentines with "increased energy" (aka faster), fast to slow transitions, lope to jog transitions, small jog circles, stop, haunch turn, back up, extended jog. In that order (The lead changes are mixed in the lope serpetine/circles)
In the past there has also been leg yields.
It's a killer for me because in the rules it says "Equines behavior and actions will all be directly impacted by the rider's horsemanship" <--- And I have a bucker, LOL. We place high when she behaves though.
Pssh.I didn't pick up the wrong lead
It's called a counter canter...
...A very advanced maneuver.
