I've only landed on my feet once....all the other times it was shoulder, arm, back and chest (did a full swan dive and landed face down...horse had majorly tripped and nearly went all the way down...he recovered and I was still trying to get centered when he took a hard left turn at the end of the arena...I sailed off to the right in very graceful fashion). I've snapped jump poles in half with my hip (horse refused the second jump of a single stride in and out, turned sideways, ducked his shoulder and let me go), broke my left arm in a very gentle fall actually, I was in two-point after a very small jump for that landing stride, horse gave a buck and since I was already forward, I didn't have time to twist to take the hit on the back of my shoulder..landed palm flat down. I've shattered the back of one helmet and cracked the brim of another.
While I don't jump anymore..I still ride...and have been for over 35 years now :)
Kylie...that centrifugal force (horse spinning) will get you every time :) A friend of mine had a little morgan mare that, whenever she got tired of being ridden would start that spin...and she was good at it in both directions...she was an ace at the western keyhole race with her ability to literally spin on a dime.
