My athletic accomplishments are listed below but they are secondary to what makes me an effective coach. I believe the most relevant part of my athletic background is my journey from an obese “finance guy” to an elite athlete.
My athletic career started when I decided to go for a walk in 1993. That walk led me to my first season of triathlon (1999) and, eventually, to elite athletics (2001). Along the way, I logged a lot of miles and made many mistakes. This site offers me a vehicle to help you avoid most of the pitfalls that I discovered.
I have studied under the leading coaches in our sport: Scott Molina, John Hellemans, Dave Scott, Mark Allen and Joe Friel. What you will find here is a synthesis of my own experience with the teaching from these master coaches.
My preferred way to interact with athletes is shoulder-to-shoulder at the training camps that we host throughout the year. In my opinion, you will learn much more from a week spent living triathlon with me than just about any other investment you can make in your performance.
I am available for consultations at $275 per session including: running through your agenda via telephone, reviewing your notes as well as post-call follow up. I find the post-call follow-up is essential to make sure that we communicated effectively.

I have no formal background in any of the three sports so I had to train both my knowledge and my body to make any real progress. This is extraordinarily valuable because I have put my studies into practice to find what will result in success “in the real world”.
I have experience with athletes that race long and short (generally Half Ironman to Ironman). My greatest success comes with athletes that have some experience in the sport (and enjoy the work), but need assistance and direction to make it to the next level. Often times this includes helping athletes execute their races properly by learning how to maximize their fitness on race day.
Marilyn Chychota McDonald
Marilyn has been involved in elite sport since she was 9 years old and is the rare athlete whose resume includes professional competition in three different sports: equestrian show jumping, cycling and triathlon.
As a child in Alberta, Canada, she began show jumping and quickly found herself on the international stage jumping at the Grand Prix Level. By the age of 21 she was one of the youngest level three show jumping coaches in Canada. She continued her career as a pro and coach with a trained stable of 30 horses and riders competing at a national level.
Meanwhile she started pursuing triathlons as an age grouper. Success came quickly. She found her calling and became a pro triathlete in 2003, racing to podium positions at Ironman events around the world, including winning Ironman Malaysia in 2004.
While she was racing as a pro triathlete, she was also competing as a pro cyclist. Since 2000 she has raced in more than 300 bike races, including competing in the full NRC circuit, Canadian Road and TT Nationals, the Australian Road and TT Nationals, and the Women's New Zealand Tour and World Cup. In addition to winning stage races, she has won several state championships in both TT and criterium racing.
Marilyn trained under some of the greatest coaches in the sport, including Ironman World Champion Scott Molina and world champion coach Brett Sutton. As well as top cycling coaches such as Kurt Innes. Her experience with the top coaches has helped further develop her coaching style.
Since 2002, Marilyn has worked as a triathlon coach to both amateurs and professionals, and has coached multiple clients to world championships qualifications in both the 70.3 and ironman distance. Many of these athletes secured podium positions in their races and USAT All-American Status.
She's lived, raced and trained throughout the world including New Zealand, Australia, North America, Asia, South America and Europe. Her appreciation and interaction with various cultures gives her a unique perspective and comfort level in working with clients based internationally.
Her philosophy as a triathlon coach is to create an environment that enables athletes to develop confidence in their abilities and to have opportunities to understand their tendencies. A teacher at heart, Marilyn enjoys sharing with her athletes the incredible gifts of knowledge she has learned and continues to learn from the best in the sport.
Marilyn is currently working full time as a triathlon coach with Endurance Corner which she has been a part of since 2008. While she specializes in coaching elite age groupers and serves as a consultant/coach to pro triathletes, Marilyn also has a deep background working with beginners, developing athletes and experienced competitors taking on new challenges. She continues to actively race and enjoy the sport that she loves.
Marilyn summers in Boulder and winters in Tucson.
I have been an athlete my entire life, playing baseball and basketball through high school and college. During chiropractic school, I developed an interest in Triathlon, and after competing in a few small triathlons in 2004, I successfully completed my first Ironman.
I supplement my personal experience with extensive knowledge in human physiology, biomechanics and ART (active release technique) as well as extensive research on periodization training, performance testing, nutrition and recovery techniques. All of these components combine into a comprehensive approach to my personal racing and training philosophy and my customized coaching.
I continue to learn and develop as a triathlete and coach. I am a big believer that in order to achieve success in the sport of triathlon you need patience and truly love to "do the work."

I grew up playing traditional sports, excelling in football and baseball. In the summer of 1992, as punishment given by my football coach, I was forced to train with the cross country runners. At the time I was 5 foot 11 inches and 225 pounds. I played linebacker and I had a decent 40-yard dash time, but the farthest I had ever run was one mile. By the end of that summer I was 6 foot and 190 pounds and was regularly knocking out 10-mile runs. My football coach moved me to free safety from the linebacker position and I was going to be the next Ronnie Lott, but after training with the XC runners over the next two summers, my point of view changed. I grew to love running more and more and graduated high school in 1995 with 5k PR in the high 16:00s.
I moved to Austin, Texas after high school to pursue a business degree at the University of Texas. The running environment in Austin was abundant and thriving and I began to immerse myself in it. I eventually transitioned to longer distance running and finished my first Austin Marathon in 3:24. As most can empathize with, I wanted to bring my finishing time down, and managed to do so the following year with a 2:52 finish.
One day, at a local track workout, a professional triathlete convinced me to buy a bike and do some local road rides as a way to take a break from running. At the time I was not particularly familiar with the sport of triathlon, but after watching a local sprint distance race, I thought it might be fun. I went to the pool and forced myself to swim until I could go 500 yards without stopping. I put some aerobars on my yellow Cannondale 800 road bike and I gave it a try. At the cost of sounding cliché, “I was hooked.” I have spent more than 13 years racing triathlons, from sprint to ironman distance, and my passion for sport transitioned to my professional life.
Endurance sports influenced me in a way that changed everything. I went back to school and earned my degree in kinesiology. I gained the credentials necessary to begin working as a personal trainer which parlayed itself into an endurance coaching business on the side. All this led to my eventual decision to pursue a Doctorate in Physical Therapy.
Triathlon encompasses such a variety of skills. The science behind training and racing became the perfect challenge. Currently, I am pursuing my dreams in graduate school and coaching has become my full time profession. I joined the Endurance Corner coaching network in 2011. I still enjoy competing and regularly race half-iron and full iron-distance events.
My philosophy: “The ABCs of life and fitness” - Attitude, Balance, Consistency
I started my first business in 1996 and I have learned that the practices that enable success in business can lead to success in triathlon. I run my training like my business and my business like my training.
My journey in triathlon started with a 50lb weight loss and continues with a Kona Qualification. I believe in having a plan and working your plan. I believe that triathlon training is a great tool to develop success in all areas of your life: family, health and work.
I take pride in interacting with you frequently by email, text and phone. You can expect a caring coach, an excellent communicator, and a strong leader with clearly defined goals. There is a depth to my craft and a true appreciation for technology and data when training. As an added bonus, I love exercise research/physiology/technology and enjoy finding the edge to what is possible.
I have a BS in Psychology and an MS in Sport Management and Marketing from Indiana University. I am a USA Triathlon and USA Cycling Certified Coach. I work with only a small team of athletes each year to give them my full attention.
My coaching philosophy is that coaches all have the same widgets. We (and even you) know the workouts but where I find coaching to be different is in the relationship between the athlete and the coach. Having been coached most of my athletic career, I know how important that relationship is. I work hard to accommodate your needs and want to make our relationship successful.
You will find that I am honest, direct, will work with you and, if you need it, against you to help you push through barriers.
I can relate. I have been there. I started as a novice age-group triathlete and have memories of getting dropped on club bike rides. Through the knowledge that I’ll share with you, I became an established professional triathlete able to compete in Olympic Trials as well as Ironman World Championships where I have been able to achieve Top 10 (overall) finishes. I feel my accomplishments dictate my work ethic and commitment.
My life experiences throughout my professional career range from holding a full time career, dealing with sidelining injuries, having two children; all allow me to relate on many levels and help you to understand balance and training.
I believe coaching is a team experience and my ultimate goal is to teach you how to coach yourself. Words that I love: empowerment, motivate, fast, inspiration. Phrases that I love: train like a pro, go past yourself, get out of your own way, be purposeful in your training. The races that I love: Ironman World Championships, Kona, Hawaii.
Having started swimming when I was 4, I am a life-long competitive athlete and have been blessed with a number of successes:
Along the way, I have coped with a range of challenges that have taught me about coping with adversity - injuries and race disappointments, mainly.
I work best with athletes that are looking to breakthrough on their swimming, as well as, helping post-natal moms lose their "baby weight". I have had successes working with athletes across the entire performance spectrum.
