Elizabeth Waterstraat — Founder & Head Coach

USA Triathlon Level III  ·  M.S. Public Health  ·  25+ Years Competing & Coaching

I’m Elizabeth Waterstraat, the founder and head coach of Multisport Mastery, bringing more than 25 years of multisport competitive and coaching experience to athletes around the world. As a USA Triathlon Level III Coach, I’ve developed athletes across a wide range of disciplines, distances, and performance levels.

My coaching approach is athlete-centered and performance-driven, blending data analysis, long-term development, and real world practicality. I start by identifying an athlete’s potential and systematically guiding them toward their potential through thoughtful planning, consistent communication, and meaningful education. My academic background includes a Bachelor of Arts in Psychology and Sociology and a Master’s degree in Public Health, equipping me to address performance through a holistic lens that integrates training, resilience, health, and life balance while progressing towards athletic goals.

As a business owner, accomplished multisport athlete, and parent of three, I understand the realities athletes face beyond training and racing. I’m dedicated to helping athletes pursue ambitious goals while maintaining health, perspective, and longevity in both sport and life.

Whether coaching an athlete to their first finish line or the top step of a championship podium, I am deeply committed to the pursuit of excellence and the success of every athlete I work with.

Amanda Wendorff — Coach

USA Triathlon Certified  ·  Ironman University Certified  ·  Based in Ohio  ·  

Amanda has been coaching athletes since 2002, which means she’s had a long time to observe what actually separates athletes who reach their goals from those who don’t. Her answer, consistently: the ones who get there are the ones who figure out how to be consistent inside a complicated life.

Balancing a career in sport law and corporate litigation, Amanda has lived this challenge herself. She understands what it means to train seriously while managing a demanding career — the early mornings, the schedule pivots, the art of protecting the non-negotiables when everything else is trying to negotiate them away.

Since joining Multisport Mastery in 2015, she has guided athletes to World Championship and Boston Marathon qualifications, age group podiums, and personal records across every distance.

Kristan Huenink — Coach

USA Triathlon Level II  ·  RRCA-Certified Run Coach  ·  Based in Southern California

Kristan coaches the whole athlete — not just the physical side, but the mental, tactical, and lifestyle dimensions that determine whether someone actually reaches their potential or just gets close.

Her philosophy is built around smart, strategic training that prepares athletes for smart, strategic racing. She’s not interested in volume for its own sake. She’s interested in building athletes who know themselves well enough to make good decisions — in training, on race day, and in the months between.

As a competitor, Kristan has been to the Ironman World Championship and brings the experience of someone who has felt race-day pressure from the inside.
