Zach cut his teeth figuring out how to ride on the unforgiving mining trails of Northern California. After watching Earthed 5, he decided to try out enduro racing and continues to seek out the most gravity-oriented events. When not racing he's smashing out big backcountry days in the Sierra Nevada, pushing dirt around the forest with a McLeod, and keeping the stoke high with Trail Peek.
