“Jeffrey is a great coach. He coached me for my first 50k, 9 Trails and 100k all within 7 months. When life threw curve balls at my training he was great at adjusting my workouts to ensure I was ready for the races and not injured going into them. One of my favorite qualities in Jeffrey is his passion for running is contagious.”


-Jenni Miller, 2019 Miwok 100k finisher

"Jeffrey Stern, a good coach that inspires, challenges, and helped me achieve great personal athletic performances in 2019. A little over a year ago, I was looking for a new coach to help me with an epic ultra running dream of mine; The Trans Atlas Marathon in Morocco, a 6-day high mountain stage race. My first attempt at the Trans Atlas Marathon in 2017, but was not physically, and mentally ready for the Atlas Mountain running conditions. 95% rocks! I knew I had to find a runner who knew how to run in the mountains, and could coach me as well.


I followed Jeffrey’s incredible mountain racing performances on social media, and I knew he would be a great runner to learn from. This past year working with Coach Jeffrey has helped me be strategic, methodical, and committed to my training plan being ready for my big Moroccan race. 2019 has been one of my strongest running years ever, but also the most challenging with a chronic injury, which I overcame for the race.


He is a wise coach who keeps me from figuratively straying from the trail with solid focus and commitment. He and I work via distance email and phone communications, as I’m based on the east coast. An athlete/coach relationship is synergistic, weekly planning, daily feedback, communications, and workout adjustments.  I’m super happy to be working with Jeffrey and look forward to continue working with him in the future."

"Jeffrey is an excellent coach. From the start, he didn’t hesitate in pushing me and took me to the next level as a runner. He provided weekly training plans, gave me focused workouts and ultimately lead me to top finishes on distances that I had never even thought I could compete in. He made me feel extremely prepared going into every race not only physically but mentally, giving me a very helpful and informative pre race chat prior to race day. Jeffrey also made me feel very proud with every finish, no matter the results.”
