Am I dreaming to think that at 57-58+ I could be competitive at training or prelim level?
However she is a yearling so no riding for the next 2 years
I would say that these might be 2 separate goals. If your goal is to go training/prelim, you might have to be open to doing it on a different horse (just in case she takes longer to bring along or decides that water is the devils spawn) Or, your young horse could be a complete eventing superstar. Good luck!!
