The Ark is not only home to over 11k of pristine, challenging, technical, groomed single track trail. The Ark is not only home to 3 horses, 7 alpacas, 2 dogs, 2 cats and countless numbers and species of wildlife. But it's home to me, the Race Director, and my wife Monique as well. So races at The Ark don't feel like you're racing at a public venue. Rather it has the intimacy of visiting and exploring a friend's home.
