I love working with runners looking to pursue a goal, whether you are a beginner or a seasoned ultra athlete. From marathon up to the longest ultra races, I will customize our training plan to focus on the physical and mental sides of training. The mind plays a huge role in running performance and I believe that it should be a focus in training to best prepare for an event.


My coaching philosophy is to create individualized programs to develop runners towards their goals. Since each runner is different in so many ways I believe each athlete needs their own personalized plan. This also includes adapting to whatever is going on in the athletes life that may require changes to the plan. Just as runners have to do in ultras we will adapt to each situation life brings.


I have been coaching athletes through Team Run Run since the start of 2022. I completed the UESCA ultra running certification before starting to coach runners to deepen my knowledge of the sport and how to properly train for the variety of possibilities running offers. I have also coached rock climbers for over a decade which has taught me so much about human physiology, program development, and communication with athletes. I enjoy working with athletes at all ages and ability levels.


I am a New Englander, born and raised in Fairhaven, MA. As a kid I loved athletics and playing outside. In high school I found running and immediately made it a part of my life. After graduating high school I started rock climbing and quickly found myself working at the local climbing gym. For the last 13 years I have been working as a route setter in gyms throughout New England, and I am currently the head route setter for Central Rock Gym in Randolph, MA.

I continued running through these years and gradually increased my mileage. In 2019 I did my first ultra races and caught the 100 mile bug. Something about the 100 mile distance has me captivated to pursue understanding running at that distance. Races aside I genuinely love running at its simplest form. The morning solo runs clearing my mind and embracing the outdoors are pure bliss.


My biggest influences have been my running coaches. Through high school I was coached by an amazing team who taught me about everything from proper training structure to the mental side of racing. More recently, coach Matt from TRR has helped me transition into the ultra world and the specifics of the ultra distances. Jack Daniels and Jason Koop have been my influences for running literature and training ideology.


My running started in high school with XC and track. I loved racing XC and my main track events were the mile and 2 mile. After high school I continued running in local 5k to half marathon’s for years before I moved to New Hampshire in 2012. At that time I developed a passion for trail/mountain running. The White Mountains peaked my interest and I started testing myself on the classic routes.

In 2019 I ran my first ultra (Midstate Massive 50 miler) and that gave me the motivation to dive into the ultra racing scene. My first 100 miler was the Midstate Massive in 2020 and that got me hooked on the 100 mile distance. Since then, my main focus is 100 milers but I still race distances down to a 5K. Aside from races I train for FKT routes frequently in New England.

    I’ve been working with Keith for a few months now on increasing my speed in the mountains, and I can already see a change in my performance. I shaved over an hour off my time on a popular 22-mile/8K trail run, and my VO2 max continues to increase. Keith also factors in my climbing training in the program, which is helpful (if you didn’t know, Keith is an incredibly talented rock climber, too)!

    I really appreciate how responsive and positive he is. He is flexible with changing my schedule around as needed for upcoming plans or trips, and provides REAL feedback on my training data, not just like, “good job, nice work.” Keith is the best, I have enjoyed working with him, and plan on continuing. Having a plan to hold me accountable (to running AND to resting) has been such a positive change for me.

    I’m brand new to endurance running and was essentially clueless about how to go about getting into the sport. I started working with Keith back in June and I couldn’t say enough good things about the guy. For starters he’s a great coach. The training program that he writes for me has been the key to my growth as a runner. I feel like I have come a long way in the short amount of time I’ve been working with him. He also is a great source of information when it comes to anything running. I ran my first trail race this past weekend and he had a ton of great advice and helped me come up with a plan of how I wanted to run the race, along with answers to any questions I had about gear and nutrition.

    Keith is a beast and if you’re looking for an online running coach he’s your guy

    I’ve been working with Keith for a few months now and can already feel such a major difference in my fitness levels. I am definitely somebody that likes to push the limits, and Keith has taken into account the type of workouts I enjoy most, while also helping me to hold onto the reigns so that I can keep running and prevent burnout or injury flareups.

    I really appreciate how communicative he is, and how we are able to strategize my training over the long term to plan ahead for any changes in my schedule, or in the short term when things come up, like poor sleep/recovery. I really enjoy having him by my side to hold me accountable to smart, strategic training, and I am growing more and more confident as I head into my next race!

    Keith has been such a help for me in my abilities to get to that next level. He has always been really helpful with my goals, assisting me to outline plans/race strategies for success, and just any odd running questions I may have along with supporting resources to backup his explainations. So much more to learn and understand, thanks for keeping it fresh Keith!

    I’ve been working with Keith for a few months and I couldn’t be happier. He is always available for feedback and discussion and writes a great training plan. My fitness has gotten exponentially better since working with him. I can’t wait to test it out in a race this season!
