Okay, hi! I am new to the sport of distance riding, and have recently contacted the AERC for help finding a mentor/sponsor, who then put me into contact with the SERA, with whom I am currently exchanging emails. Now, my horse is an 18 year old Arabian gelding, barefoot, and has NEVER had any soundness issues in his life. You can not tell his age unless you look at his teeth. The vet said he was suitable or daily hard riding, and the farrier is consistently amazed at the quality of his feet. He is very, very nervous and ancy in the arena due to a previous owner, but is a dream horse on the trail (other than not many people like to ride with us because we are rather "speedy"). He is 14.2 hands, and 850 pounds. I am 5'4 and 110. Is he suitable for endurance/LD rides with the right conditioning, or am I just going to kill my poor horse? Also, I am considering going treeless, any recommendations? I have been looking at the barefoot saddles at action rider tack, as they have a demo program. Anyone have experience with these?
