I specialize in the roads and the track in distances including the 5k, 10k, half marathon, and marathon, as well as the trails (I’ve done most of my own training out on long single-track over summer and fall in Colorado and now in Utah, so I am well acquainted!) I have experience both crewing and pacing in ultramarathons as well.

I believe in implementing strength training into your routine and can prescribe specific strength/weights workouts to fit in your training schedule. I am also familiar with incorporating effective cross-training into running training plans if needed, and can help you work through injuries while keeping fitness up. While I work with any gender, I do have a good base of knowledge on the female athlete body as I spent graduate school studying women’s physiology in endurance sports.


I believe in a methodological approach to training that is specific to you as an individual. Reaching the athlete’s goal is a team effort between athlete and coach, so we will work together to create a plan that is best for you. This includes consideration of not only your current fitness level, but the other important aspects of your life like your family, friends, career, etc. Your training should fit into your life and be an enjoyable and fulfilling component, not an added stressor.

I also place emphasis on consistency, positivity, and doing everything – hard workouts, easy days, recovery, sleep, nutrition, etc – with purpose and intent. As my college coach used to say, “Good days turn into good weeks, good weeks turn into good months, good months turn into good years, and good years turn into good careers.” Showing up for yourself in whatever capacity you have to offer each day is what builds a solid foundation, and my goal is to help guide you along the way.


I started officially coaching in the summer of 2022. I have experience assistant coaching at the NCAA DII level at Western Colorado University as well as on the individual level.


I grew up by the ocean in San Diego, CA with my mom, dad, older brother, and younger sister before moving out to the mountains of Gunnison, CO, and now to Salt Lake City, UT. I graduated from Western Colorado University with my B.S. in exercise and sport science and my M.S. in high-altitude exercise physiology, where I studied the effect of the menstrual cycle on performance in endurance runners for my master’s thesis. I spent a year post-grad in Gunnison assistant coaching xc/track and teaching in the biology department at Western. I know live in Salt Lake City, UT with my crazy pup Ilios, where I have plans to pursue my PhD in exercise and disease while continuing my own training and competing on the roads and trails.

I love running as many miles as I can and exploring the mountain trails with Ilios at my side. I recently caught the cycling bug too and have been pushing my boundaries on two wheels in addition to on my feet. I think science is cool and nature is rad, and am equally likely to be found posted up in my local coffee shop as I am out on the roads and trails. If I’m not out running, I’m usually creating art, reading a book, or teaching myself a new creative skill.


My biggest influences in my running and coaching are my own coach, Thom Hunt, as well as my past college coaches and teammates at Western Colorado University. I highly respect my coaches and learned that the respect you give out as a coach is the respect you gain in return. They taught me the importance and power of believing in your athletes and striving for nothing less than your best. My teammates at Western Colorado University are some of the toughest athletes I know, and taught me how to dig deeper into myself and always find more in me as both an athlete and person. My goal is to instill these lessons into my own athletes moving forward.


Finding a coach who is a great fit for you is really important. We encourage you to email your coach prior to signing up so you can connect, communicate, and ensure a good athlete/coach fit.


I started running in 9th grade on my high school cross country and track programs in San Diego, CA and quickly fell in love with the sport. I didn’t have any raw talent so always had to work incredibly hard to accomplish my goals, but I believe that only strengthened my love and respect for the sport. After competing for two years at Cuyamaca Community College in San Diego, I transferred to SF State and then to Western Colorado University on scholarship where I competed from 2019-2022 as I finished first my undergrad then graduate degree. In my time at Western, I became an All-American in cross country as well as led my team to a podium finish at the national championships. On the track I specialized in the 5k and 10k with a specific love for the grittiness of the 10k, running my personal best of 35:44 in my last year of grad school. Post-collegiately I have plans to move up to the marathon with goals of running an OTQ and competing at the trials.

    Working with Lexie has been great so far! I ended up beating my half marathon PR by 15 minutes after only 2 months of working together. If you’re struggling with base building and consistency like I was, Lexie is a great option!
