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.

Racers will begin with a 18k gravel road prologue in a loop south of The Ark. Although technically this is a gravel “road” segment, racers will want to conserve their energy as they are challenged by over 1000 feet of elevation change over the full 50k. Once that little jog is complete, racers will then enter the trail system to tackle 3 loops of the 10.5k of Insanity course.
