Good for you Joe. If you want to be competitive in endurance an Arab or Arab cross is the best way to go. Any horse can do endurance if you are just in it to finish but to win or place high, most are doing it on the Arabs!
Totally jealous of those miles. I just now have 186 miles. Last year at this time I have 270 so I am 84 miles behind. Dang, last year we rode so much because we didn't have any rain outs - this year we have been hampered by too much rain. It poured buckets Saturday evening. Sigh....going to ride in the arena in just a little bit!
