“What impressed me the most about Matt and Boulder Underground was his level of interest to develop his athletes in all aspects of the sport. I asked him to train me to my first Boston Marathon. And although the weather in 2018 was absolutely dreadful, Matt kept me motivated and optimistic.

Typically the day after a marathon the last thing I want to be doing is thinking about racing again. But that’s exactly what I did. I wanted more. I felt like I was in the best shape of my life, and I was excited. I wanted to know what else was possible... and I still do.

Being coached by Matt changed my approach towards running. The drills, injury prevention exercises, dynamic warmups, all the little things that never mattered before now do. The system works. Over three years later I’m still healthy, motivated and tapping into potential I never thought I had.”

“Thanks to Matt I'm running faster, further, and more frequently than I have ever done before! New to intentional training, he explains the "why" behind workouts (hi easy days!) and is incredibly genuine in his approach to learn more about me and my goals. Even in the short time together he has challenged me to expand my views of myself as a runner and I cannot wait to see what the future holds.”

“After working with Matt for a few months, my perspective on training has changed for the better. I’m learning how to take the pressure off myself and run for the joy of it. I feel less stressed about workouts and upcoming races because I’m not striving for perfection, but making progress towards my long-term goals.

Boulder Underground understands that the mind plays a powerful role in performance. Matt not only focuses on my physical strength and endurance, but also encourages me to develop effective coping strategies so I can show up on race day confident in my ability to succeed.”

“I have known Coach Matt for the better part of two decades. We first raced in High School and then became teammates while running together at the University of Florida. We remained friends after college and then after taking some time off from the sport I began training again in 2012. I reached out to Matt and we've been working together in some capacity ever since.

I qualified for the 2016 Olympic Trials under his guidance and then left the sport for a few years to travel the world and pursue other passions. Then in my early 30's I decided to get back into competitive running again and Matt was the first person I called.

Within a year, I made my debut in the Marathon running 2:18 to Qualify for the 2020 Olympic Trials all thanks to Matt. I then went on to PR in the 1500, 5k, 10k, 15k, and Marathon. I lowered my Marathon PR to 2:13:04 in 2019 and then finished 24th at the Olympic Marathon Trials beating many professionals along the way.

Despite working with Matt from halfway across the country, we were able to accomplish all of my goals and had a blast doing it. I've never had an injury under Matt's guidance and had success in all of my Marathons.

Matt has a unique gift of being able to deliver short term success while always keeping an eye on the big picture. His seemingly endless knowledge of the sport is only surpassed by his love for it. I am also a Coach and I have helped many runners reach their goals and dreams. And most of what I've learned is from working with Matt over many years. I regularly refer runners to Matt and I will continue to do so as long as he offers his gift to the world.”

“Boulder Underground keeps me grounded through professional and personal life changes. Whether I am setting 4:30 a.m. alarms to run or working on my mental health, BU is fundamental to my success on and off the roads. BU’s focus on being “the eye of the storm” sets Matt’s coaching and training apart from the competition. His comprehensive approach continues to make me a stronger athlete!”

“Boulder Underground is the REAL DEAL! Training and being guided under Matt's wing showed me how much true potential I was capable of. The motivating energy that is throughout the BU group is so uplifting and helps keep you on track for your goals. I was training for the Boston Marathon 2020 which ended up being canceled. Matt helped keep the momentum going and was creative in a way for me to put my fitness to the test, even though it was not my A race, the Boston Marathon.”

“I asked Matt to train me so I could run the 10K Bolder Boulder with my daughter- who already trained with him. The challenge: I was a 58-year-old achy athlete who lived across the country at sea level and had continued to be active but hadn’t run regularly since college... and frankly didn’t like it much. Matt’s challenge to me: Would I commit to the workouts? Matt’s Challenge to himself: for me to learn to love running.

Matt’s training plan kept me safe and opened my eyes to the importance of “active recovery days” rather than just pushing harder every day. With strategic scheduling of longer, shorter and harder workouts I was able to keep my commitment to the program and was amazed to see my progress every week. Not only did I surpass my goals for the Bolder Boulder, but I never could have imagined that I would be able to run 9 miles during a training run.. far more than I had ever run in my life.

As for my love of running... While I can’t say I’ve become a loyal runner, I have a newfound appreciation for it, and continue to run “just for fun” intermittently thanks to the confidence that Matt helped me develop in my ability to get out of my comfort zone and onto the road.”

“Boulder Underground has changed my life over the past year. After a tough post collegiate transition to racing Matt welcomed me with open arms to a team and program I could channel my competitive energy while keeping long-term goals in mind. He has taught me to be patient, trust in his training and that working on the little things outside of running is what makes us better athletes. I’ve accomplished things in the last several months I would never have thought a year ago. I wake up excited to go to practice and grind out hard efforts at 6 am before work. Matt and Boulder Underground as a whole, is very special. I feel grateful every day to be a part of something so much bigger than myself.

Here’s to many more PR’s in the future 😊”

“Nicole coutures each plan to your body and how it is impacted by her training. Her style of training is effort based which fosters an environment of quality training over quantity.

Nicole listens and makes you feel heard and validated. I trust and respect her input and know that if I am honest and open she will work to push me through my insecurities.

She does this while also pushing me outside my comfort zone not just in effort but in routine. Placing value on all the little things I don’t put much value in, but really make the difference.

Nicole wants nothing more than for you to succeed at your goals and will be there every step of the way. As I move forward from a previous over-training injury into my ultramarathon training, I am excited to see how the 2021 season progresses.”

“When I began working with Nicole, I was coming off of a stress injury. My running needs had to be tailored to fit my long term running goals, she helped me work through all the mental and physical roadblocks that came with recovering from an injury. I’m now about 9 months into her training and I have never felt more confident and strong with training. If you’re looking for personalized training and thorough communication, Nicole is the coach for you!”

“Matt started coaching me shortly after concluding my college soccer career. Running was a new sport for me in general, and he was really starting with the basics of running that I had yet to experience. It didn’t take long for me realize I loved running and Matt was a key component to my development in the sport.

I can’t say enough about his commitment to building a strong foundation within my running toolbox that allowed me to keep progressing now 7 years later in the healthiest way possible. While Matt has taught me nearly everything I know about running at this point, what I needed most from him is to learn to believe in myself again after ending soccer unfulfilled. That alone has been monumental in him/ Boulder Underground being with me from the transition from college soccer player to US marathon Olympic trials qualifier.”

"I have never had a dedicated coach for running since before BU and removing the energy required to coach myself has been one of my favorite things. My other favorite part is Matt’s methodology and the results that have come from it. I have been running faster than I ever have in my late 30s and have been doing the least amount of miles I ever have. I also have not been injured for more than a week or two which was a dramatic change from before BU."

“Having the opportunity to know Matt for so many years, it came as no surprise to me that he became such a successful runner and coach. What I couldn’t have predicted is what makes him such an incredible coach. Matt truly understands people. Not just the PRs they can hit or progress they can make, but he understands the athlete as a whole, and the level of investment he has in his athletes in unparalleled.

Matt has a way of building the confidence of the athlete and creating a space for them to simultaneously set big goals and believe in their ability to achieve them. His optimism and relentless belief in his athletes is infectious. The creation of Boulder Underground was simply an extension of something Matt was already building through his coaching and involvement in his community. BU meets a need that as athletes, we crave - an organized, fun, and supportive group that brings out the best of everyone who is fortunate enough to be involved with it.”

“I could not thank Boulder Underground enough. In the last year my performances have improved dramatically working with BU. I have used programs based on the ideals of Jack Daniels, Renato Canova, Arthur Lydiard in the past, but I would say nothing has worked better than the philosophy that BU uses. The mindset endowed by BU on their athletes is a mindset that you can apply to everyday life. My level of confidence has increased and my level of fear has decreased in all my endeavors.

I have PRd in every distance from 3k - Marathon working with BU. Workouts are made specifically for you. Pre-race hype talks are also made specifically for you. The best coaching service I have ever used.”

“After knowing Matt for years, I can attest to his attention to detail in every aspect of the sport. Matt is a true student of running, taking learnings from years of being around some the best coaches and athletes in the game. He prescribes training based on physiological objectives, but most importantly he relates to people. I have big goals for over the next four years, and Matt is the right coach to share my journey with.”

"Matt was such an amazing coach and person. His training helped me to qualify for both the 2016 and 2020 Olympic Marathon trials.

Before working with him, I didn't really ever think I would be able to get back into competitive running after burning out in a D1 athletic program. Matt made training fun again and helped me to believe in myself as a runner and human. I would recommend Boulder Underground to anyone really looking to get to the next level."

“After becoming a mom, I wasn’t sure I’d be able to return to running at the same level I was before having a baby. I assumed my PR years were behind me. Running with Boulder Underground and being coached by Corey gave me the self-confidence I needed to prove myself wrong.

I’ve run faster times than ever before from the 5K through the half marathon with the schedule, guidance and company of this team. I can’t wait to conquer more goals in the future knowing I have the full support of Boulder Underground behind me.”

“Boulder Underground is one of the best communities of athletes I've ever been a part of. I worked with BU coach Corey Wall throughout most of 2020. The program he put me on was tailored to my specific goals and helped me achieve several PRs. Corey got me in the best condition I've ever been in, all while avoiding injury.

I am 37 and a father of two so it was really fun to knock off times that I hadn't run in a really long time. Not only that, I've had a blast in the process and made some amazing friends.

It's obvious that Corey and the other BU coaches really care about their athletes and the community that BU represents. Finding BU was one of the best parts of our move to Colorado...and that's saying a lot because CO life is amazing!”

“I am not an easy person to coach. I'm stubborn. I get in my own way, a lot. I'm impatient, injury-prone, sensitive, and slow to trust.

Yet thanks to Nicole, I've come a long way. Not just in training, but in life.

When I started training under Nicole, I was a burnt-out, former D1 athlete, struggling to balance major life changes with maintaining my mental and physical health. I wasn't performing well in any area of my life, let alone running. She met me where I was. Nicole listened to my story and goals, and positioned herself as a guide, letting me control the pace and direction of training. Her holistic approach to running continues to challenge me to set sustainable training goals and keep the long-range-view in mind, which, for me, means that health and happiness are just as important--if not more--than a PR.

Part of what makes Nicole's insight so invaluable is that she's been there herself; she knows what runners struggle with, and more importantly, she knows how to overcome those struggles. Nicole is more attuned to her athletes than almost anyone I've been coached by, and she communicates training philosophy and objectives in a clear, creative way that tends to stick with me long after a workout.

I still struggle with mental blocks and staying healthy in general, but Nicole is getting me there. After years of going through the motions, exhausted and unmotivated, I finally feel like I'm beginning to race again. She's given me strategies to take control of what I can in my life, and helped me re-prioritize my goals, with a view toward longevity and enjoyment. As a result, I'm fitter than I've been in years, and having a whole lot more fun.

Nicole is a great coach, and a great person. Trust her with your dreams; you won't be disappointed, no matter what the journey brings.”
