Zachary "Zack" Russell is an ultraendurance athlete living in the high mountains of Breckenridge, Colorado. I began running while a freshman in college after a trail run with some friends over Spring break and could barely keep up. After that the rest is history, I went back to school and devoted myself to running. I began trail running in 2016 while in grad school in Colorado Springs with my first trail race being Pikes Peak ascent. I love competing in all types of endurance events including gravel/mountain bike races, ultrarunning, bikepacking, and cookie eating contests.
I am passionate about helping others achieve their endurance and race goals. I enjoy learning about the entire athlete. Their life, nutrition, family, other hobbies, and what makes them different. I have had the opportunity to enjoy many experiences and have educated myself in multiple aspects related to endurance sports including training, nutrition, and strength training.
I continue to enjoy long adventures in the high alpine of Colorado, summiting 14ers, chasing mountain goats, eating more than enough cookies, and competing in the occasional trail race.
