I don't care how good your horse is going forward, sideways, backwards, jumping up and down, or turning...If you can't stop, you are asking to get you and your horse killed.
I heard a quote once from a cutting trainer, "A good run is built on the stop, but everyone focuses on the turn"
I believe that qualifies in barrel racing too. A good run is built on solid foundations and slow work, but everyone focuses on fast runs and hard turns.
Pssh.I didn't pick up the wrong lead
It's called a counter canter...
...A very advanced maneuver.
