I know that having the 'heart' or drive for endurance, along with soundness, can be a huge factor for a horse to succeed (which I define as finishing the race). Any way to tell if a horse might have it aside from going out and doing it? And secondarily, would doing a LD length ride NOT at an actual ride be telling at all? I know the atmosphere of a race is far different than just going out on our own. Anyone want to come down to Corpus and do a long ride on the beach with me? How do you do enough miles for training? This 9 mile track is about the furthest I have without trailering, and the idea of doing it back and forth a couple of times, while doable, isn't particularly appealing, but I know we need to start going longer if I want to be able to do LD at all this year.
