The mare I show is a DEADHEAD. Her flatwalk is the pace of a horse's normal walk, and her running walk makes me feel like I'm crawling compared to all the rackers in the show ring. :P She stands tied FOREVER. Her saddle falls off of her back, she just looks at it. She neighs when she sees me coming for her in the field, and stands at a respectful distance to let me come into her space to halter.
However, put a beginner on her, she PACES to no end. She needs strong, clear cues. I think that with Walkers, you HAVE to have a trainer working with you.
I am looking to move up and buy my own horse when I have the funds, but until then, I am riding only that mare(her brother, a champion racker I liked, was sold) under the guidance of my trainer. And even when I get my horse, my trainer will be riding it 30 min a day to help set gait, and she will ALWAYS be around when I ride.
