Specialties
Trail and Ultra, with focus on improvement and enjoyment over strictly results. Would love to work with athletes that are just getting started, or training for goal events, and want to keep motivation high. Being a part of the clients’ journey, and supporting those efforts, is what it is all about! Adapting strength and cross training to build strong runners is also pivotal.
Philosophy
I believe we are all born runners, regardless of ability or performance. The process is the goal, and enjoyment along the way is the payoff! My goal will be to get my clients prepared mentally and physically for the task at hand, and get them to the finish feeling proud and accomplished.
This isn’t training, this is living. – Rocky Mountain Runners
Coaching Experience
Now in my third year of coaching with Team RunRun and I have had the privilege of helping athletes reach major milestones: from first ultramarathons and 100-mile finishes to qualifying for the Boston Marathon, racing on the international stage at UTMB and running sub-19 at Western States! Nothing motivates me more than seeing athletes realize they’re capable of more than they thought possible!
As an ultra-runner myself, I worked with a coach for several years, so I understand both sides of the relationship. I know what it’s like to build patiently through seasons, to adjust when life shifts, and to evolve goals as fitness and experience grow. That perspective shapes how I coach. I aim to be collaborative, adaptable, and always focused on long-term development.
I believe success comes from thoughtful structure and smart progression. Building a logical race calendar is just as important as the weekly mileage. Each season should support the next, while still leaving room for adventure and the realities of everyday life. Whether you’re training for your first ultra, chasing a breakthrough performance, or aiming for a bucket-list race, I’ll help you train with purpose, confidence, and durability!
About Me
I began running 1 mile a day a little over 12 years ago. Fast forward to now, and I have completed over 50 ultras, including Hardrock (x3) and Western States 100! Being out on the trails, with friends and family, is where I am most fulfilled!
Big Influences
I have trained under some of the biggest names in the Ultrarunning space (including TRR Co-Founder Matt Urbanski). Pulling from these experiences as well as connecting with and drawing inspiration from cutting edge thought leaders in the sport is a personal passion. I believe in building ultra-mountain athletes that are durable, and ready for the long haul – to do this I believe in taking a holistic approach to training and how the approach to endurance fits within the construct of our daily lives.
Race History
Started out with a 50 miler in November 2013 (Red Rock 50), and followed that up with another 50 (Sean O’Brien), three months later. Since then, I have run 4-6 ultra per year. I believe in scheduling a yearly race calendar, and building a training schedule from there.

Hong –
Coach Kyle helped me prepare for last year’s Kodiak 100K trail race, which was my first ultra race. During training, I injured my Achilles and started to look for coaching service. Coach Kyle provided strength workouts that did not aggravate the injury while helping strengthen my Achilles.
After my recovery, I felt stronger on the trails. Throughout the training season, as well as before and after the race, Kyle always answered my questions and walked me through the details.
I highly recommend Kyle to anyone training for an ultramarathon. Beginners like myself, in particular, will benefit greatly from his guidance.
Ashley Valentin –
Working with Kyle has been an awesome experience. He does a great job of challenging me while also listening to what I need and checking in on how I’m feeling throughout training. Every workout feels intentional, and he knows when to push me and when to adjust based on how life is going.
He’s helping me train for my first 100-mile race, and I couldn’t be more excited to get to the start line. One of the things I appreciate most is that he keeps running fun while recognizing that training has to fit into real life. I always feel supported, encouraged, and confident that I’m building toward my goals in a sustainable way.
If you’re looking for a coach who truly cares about both your performance and you as a person, I highly recommend Kyle!
Natalie Burkhard –
I’ve been working with Kyle for a few months now, and I highly recommend him! He’s organized, responsive, knowledgeable, and helpful. I find him to be really supportive and present. I especially like the app he uses (Steady State) because unlike others that prior coaches have used (like Training Peaks or similar) it helps me keep track of how I’m doing holistically because factors like diet, sleep, stress, mood all affect how I perform, and I like that that information is readily available and digestible for my coach. Will come back to give a fuller review after my race in 4 months, but I heartily recommend him to anyone looking for a running coach!
Jen Wold –
Coach Kyle is responsive, empathetic, encouraging, and knowledgeable. He’s patiently working with me as I navigate a couple injuries. He’s been a great collaborator and communicator. Just hire him already!
Maggie P –
I’ve been working with Kyle for only 2 months, but I can already feel a noticeable shift in both my strength and my mental attitude towards running. He has a holistic approach to running that is the perfect balance of guided programs and flexibility to spend time on runs with friends. I never feel like I’m choosing between following my training plan and doing an adventure that I want to. Similarly, I appreciate having a coach that understands that running is not my entire life, I have a job, and friends, and a dog that all need attention to – and I feel like Kyle as a coach manages training around your life not the other way around. He is a relentlessly encouraging person, and I look forward to continuing my training with him.
ALICIA SUTPHIN –
I’ve been coached by Kyle for 2 years now, and I love that he makes training stress free and fun! He makes sure I’m not overtraining, and that running is about being psyched to do what you love. Big thanks to Kyle for helping me achieve my goal of a top 5 female finish. I feel very lucky to have found such a great coach.
Junine So –
I worked with Kyle for about 6 months to prepare for my first 100 miler and I couldn’t have had a better experience! This was my first time working with a coach and I have no regrets. While I had trained on my own for a 50k and 50 miler in the past, I realized 100 miles was a big jump up so I wanted to lean on Kyle’s extensive ultra experience to help me take the guess-work out of my training. Working with Kyle surprised me in that I ended up doing lower volume than I otherwise would have; in retrospect, if I had been training by myself, I would have likely ended up overtraining and getting mentally burnt out or injured. I’m really impressed by how Kyle tailored my plan to me and my background as a runner who is newer to distance running (having only started running five years ago), and I got through the whole training block feeling energized and still loving running by the end.
Kyle was also an amazing resource for all things fueling and heat training (critical for my desert race as someone coming from the Pacific Northwest!). I really upped my long run/race fueling game working with him. In addition, Kyle was always flexible and understanding when it came to accommodating scheduling needs (e.g., travel, busy work periods, special long run adventures I wanted to do with friends, etc.) and extremely supportive when I had an injury scare close to my race.
Finally, Kyle was amazing when it came to race prep and logistics. He happened to be coaching two other athletes running the same race as me and helped us borrow a tent and cooler for the race. It was very special being able to race together (though completely by luck) and all three of us finished despite the DNF rate being more than 33%—each of our first successful 100 milers!

I’ve been working with Kyle for the past 6 months to train for my second 100-miler, and I couldn’t be happier with the experience. I originally invested in a coach because the world of training theory can feel overwhelming, and I was looking for some structure and guidance. Kyle brought exactly that, but in such a grounded, thoughtful way. His approach to training pushed me to grow while still keeping things sustainable and healthy, never over the top, always measured. He also has a great way of reminding me that, at the end of the day, ultrarunning is about the journey and having fun in the mountains, which helped keep my training both challenging and joyful.
Midway through my build I broke my foot, and Kyle was incredibly supportive throughout my recovery. He worked with me to adapt my plan week by week, tailoring running and cross-training to wherever I was in the healing process. That flexibility and care made all the difference.
I’d recommend Kyle without hesitation to anyone looking for smart, supportive coaching.
Bradley Roberts –
I wanted to write an update at the end of my second season with coach Kyle. In the 18 months since my last review, I have achieved much more than I expected working with Kyle. Not only did Kyle train me to complete my first 100 mile race, but to enjoy the training, not feel overwhelmed, and ultimately do well at the race itself. While I was focusing primarily on ultra distances, Kyle also improved my speed and he guided me through qualifying for the Boston Marathon and then run a PR at Boston. His plans are highly tailored to my individual goals and are calibrated to how I am feeling week to week. He is also available to talk through schedules, race strategy and nutrition, and long term plans.
Most importantly, Kyle keeps me running and enjoying it. In the past, I would often train with a specific goal/race in mind and then burnout and struggle with consistency once it was completed. Kyle’s supportive, laid back, and understanding approach has helped guard against burnout and has kept me focused beyond individual races and has made me a much more consistent runner. The consistency has kept me improving and I can safely say that I’m a better, faster runner at 43 than I was when I was 33.
As a dad with a demanding career and family life, I often have to juggle many competing priorities. Kyle’s coaching style recognizes running is just a small part of my life and I dont feel the same pressure as I have has in the past running with other programs. This too has helped keep me engaged and on track in the long term.
In all, I could not ask for a better coach or experience. Thank you!

Coach Kyle is amazing. He’s helped me reclaim the joy and freedom of long trail days and intentional training. He’s helped me through an injury and he has me back on the trails injury free. He’s my accountability partner for keeping my training smart and sustainable. He is so knowledgable and experienced and he knows exactly how to help me reach my goals. He’s engaged with my training and my journey and I’m very grateful to have him by my side during my running journey. If you’re looking for a coach that is engaged, knowledgable, experienced, empathetic, and motivating then Coach Kyle is your coach. Sign up with him today and find out what you’re capable of!
Gilad Solter –
I’ve been working with Kyle for a few months now as I trained for my second 50K race, and I couldn’t be happier with the experience. His coaching has been so effective and enjoyable that I’m planning to continue working with him as I take on my next big challenges—training for my first 50 miler and 100K races this summer
I can’t recommend Kyle enough as a running coach! His training plans are incredibly well thought out, providing a solid foundation for progress while staying flexible to accommodate life’s inevitable changes. Whenever adjustments are needed, Kyle adapts quickly, ensuring training stays effective and enjoyable.
Beyond his expertise in structuring workouts, Kyle brings a wealth of experience as an ultra runner. His deep knowledge of endurance running is evident in his guidance, but what truly sets him apart is his approach—he emphasizes the journey, making sure running remains fun and fulfilling rather than just a grind.
Maria –
I’ve been working with Kyle since the beginning of the summer and it’s been fantastic. Very available and responsive as well as encouraging.
Bradley Ames –
Working with Kyle has been a complete game changer for my training. He is encouraging. He listens and adjusts. He asks the right questions and makes excellent suggestions. He has a wealth of knowledge and experiences. He is engaged and available. Full endorsement!
Alex Eaton –
Kyle is everything I could’ve hoped for in a running coach and more. We’ve worked together towards my first 50 miler. His depth of experience doing this dozens of times himself is obvious from the start. Detailed training plans, feedback after my workouts, checking in on progress and how I’m handling the training as we go. I’m also a skier and Kyle worked with me on figuring out how to balance skiing with my training in a sustainable and fun way, while making sure I stay on track towards my goal. Even though he is highly accomplished, his constant focus on enjoying this whole running thing along the way is appreciated. Beyond the tactical planning and feedback of the runs themselves, Kyle has also been brilliant in discussing hydration, fueling, shoes and gear, and chatting about the mental side of this whole endeavor (which is a big part of it). Working with Kyle is like getting a running mentor along with a coach that programs your training. Side benefit: his email newsletter he sends to his clients is great as well exploring many different mental and physical aspects and recommendations in this pursuit.
I can’t recommend Kyle enough.
Alicia Sutphin –
Been working with Kyle a little over a month and he’s been great! He builds plans that make you feel confident while working around your life schedule. He’s very encouraging and always takes time to review your runs and make sure you feel good about them.
Alex Roberts –
Ive had the pleasure of working with Kyle training for my first 100 mile run. I am a run coach, but he is the RUN COACH of run coaches. This man embodies everything you could hope for in a mentor. Not only is his expertise in long-distance running unparalleled, but his ability to inspire, understand, and demonstrate patience truly sets him apart. From the moment I began training under his guidance, I felt empowered and supported every step of the way. His deep understanding of what it takes to conquer long distances not only improved my physical abilities but also instilled in me a newfound confidence and determination. If you’re seeking a coach who is not only knowledgeable but genuinely cares about your progress and success, it’s Kyle.
David Rabe –
New to Distance and new to having a Run coach. 2 Months in and really enjoying working with Kyle. I enjoy the personalized attention and tailored specific workouts designed to build up to my goals. Seeing great progress. Kyle provies daily feedback which is highly motivating. Solid attitude and sense of humor.
Bradley Roberts –
Kyle is simply an excellent coach. He is currently helping me train for my first 100 mile race. His training plan is clear, well thought out, and he takes the time to explain what his goals are with the runs. He tailors each week depending upon my current condition and schedule. I have already noticed significant improvement in the first 8 weeks of working with him.
Perhaps more important than providing a good training plan, he’s just a great guy. He is encouraging without being overbearing and holds me accountable without making me feel guilty about missing a day here or there.
He is also extremely available and responsive to talk through any questions I have as they come up.
I have really enjoyed working with him and would highly recommend him to anyone who wants a steady and knowledgeable coach in their corner as try to improve their running or are attempting to accomplish a big goal.
I hope to continue training with him for years to come.
Thanks Kyle!
