Keith Chun   K3Multisport

I am a high school Spanish teacher and swim coach as well as a Level 1 USAT triathlon coach with almost 30 years of experience in the sport of triathlon. I specialize in athlete-centered 1:1 triathlon coaching - from beginner to elite, sprint to full distance racing and training. In addition to 1:1 coaching, I offer training plans specific to triathlon, swimming, cycling, and running. Hablo español.


I completed my first triathlon at the age of 15 in 1988. Later as an adult I turned my attention to long course racing and training where my passion for competition drives me to continue to strive toward my ultimate goal of competing in the Ironman World Championships in Kona, HI. Along the way, I have completed and continue to target short term goals as "stepping stones" toward this ultimate vision. I have completed 3 full distance Ironman races, several 70.3's and countless sprint and olympic distance triathlons. Recently, I reached my goal of qualifying to run the Boston Marathon. I mention all of this not to massage my ego, but to highlight the importance of setting SMART goals for one's self. Without a goal in mind, the athlete cannot truly reach their full potential.
I have had a passion for teaching all of my life. I have spent the past 16 years teaching high school English, Spanish, and history as well as coaching competitive swim. After witnessing so many athletes randomly going about their training without structure or organization, I have turned my attention to teaching athletes the value of a structured, organized, well-planned, data-driven training plan. Coaching is more than simply prescribing workouts for an athlete. Coaching is teaching and I am a coach who will teach you what you need to know to reach your goals. Hablo español.
