In March of 1999 my endurance gelding developed a
thoroughpin and I had my vet look at it. He ultra sounded it and said to
keep riding him as it wasn’t bothering him. Well, I think he was
right as I completed a tough 55 on him last Sunday at Cuyama Oaks and Koztarr+/
now has close to 5,100 miles. He is 17 this year and has been doing
endurance since he was 5. I have never had a vet comment on it as it is
only considered a blemish. My advice to you is to keep riding your horse
and don’t be too concerned about it. I had forgotten about it until
I read the recent post on ridecamp. I wrote to ridecamp on March 10, 1999
asking if anyone had any experience endurance riding a horse with a thoroughpin
but never received any responses.
