CustomiZed training plans 🎯

Your training plan is created with your schedule and goals in mind

As a team of coaches we are are there for each other - to offer advice, knowledge and encouragement - when needed. We acknowledge that we each have our own strengths and weaknesses, but recognise that our true power is by coming together.

To us, writing the program is the easy part. Putting all the pieces together so that we learn your reason 'WHY', and fitting that into your daily life, now that, is the art of coaching.

We commit to doing our utmost to challenge, motivate and prepare you to achieve your goals with thoughtful planning and guidance. When something comes up and we don't know the answer, we will help search out those answers by reaching out to experts in the respective fields. At JDC we aren't looking to say we are without doubt the best coaches out there - we know and respect many other endurance coaches that do phenomenal work. What we do know, is that we endeavour to give our hearts and souls to help you achieve your goals in a fun and caring way.

Lauren Brandon

Lauren has been under the JDC banner as a professional athlete and coach for a number of years. Her passion and joy for the sport shines through not only during her racing, where she always has a big smile on her face, but also through coaching athletes to their goals. Lauren’s athletes can be seen striving for a wide range of goals from biking around Italy, completing their first triathlon, to competing at the Ironman World Championships. Lauren enjoys coaching athletes on all levels and getting them to any finish line that excites them.

“I love the challenge of finding what motivates athletes year in and year out and helping them achieve their goals, no matter what it is. Each athlete is completely different, so my focus is how we can keep an athlete happy and healthy while also balancing life, training, and racing. Nothing makes me happier than seeing athletes achieve what they set out to do and have fun along the way.”

Lauren has had a long sporting career that started as a swimmer and after the 2008 Olympic Trials made the switch to triathlon. What started out as an ITU career, has turned into 8 years of focusing on full Ironman races and she still loves to race. After being asked by someone to coach them a few years ago, Lauren knew the only way she wanted to coach was under the JDC banner. “It’s amazing to learn from Julie and the other coaches and to have that team of knowledge and expertise to learn from on a daily basis”. With 10 years of swim coaching, a few years of triathlon coaching, and over 30 years of training and racing, Lauren is ready to help all of her athletes get excited about reaching their goals and getting to their first or next finish line.  

Katie Kyme

There is one word that can describe our JDC coach, Katie Kyme; inspiring.

Katie is a seasoned competitor, and dedicated coach. She overcame significant challenges in her career, only to return to sport and rise to the ranks of a podium professional. Katie demonstrated her unwavering passion for the sport over her 25 year of competitive career. Her racing achievements include several Xtreme Triathlon and Ironman podiums.

Along the way, she has discovered an even greater passion for coaching. Her unwavering commitment to helping athletes achieve their dreams shines bright.

A Passion for the Sport: Katie's journey began as a young athlete captivated by the beauty of the three-discipline sport. Her love for triathlon is infectious and spans across all age groups and skill levels. She understands that triathlon is not just a sport; it's a lifestyle. Her relentless enthusiasm for the sport is what sets her apart as a coach. Katie's philosophy is rooted in the belief that every athlete, regardless of their current level, has the potential to be extraordinary and achieve their best. Her coaching offers tailored training programs, insightful guidance, and a genuine personal investment shown through her unwavering support for each of her athletes. She wants each of her athletes to become the best versions of themselves and enjoy the process and has over 10 years of athlete results to prove it.

Whether it's finishing a first time sprint triathlon, conquering an Ironman, or chasing a world championship birth, with KT as their coach, athletes find a mentor who believes in them, inspires them, and guides them towards extraordinary achievement in sport and in life.

Rachel Joyce

Originally from the UK she now calls Boulder home, Rachel lives with partner Brett and sons Archie and Benjamin and pup Maggie. She has been coaching since 2016, but having coached solo for 5 years, she craved more collaboration and community and so in 2021 Rachel joined the JD Crew. “I saw what Julie was building with JDC and I wanted to be a part of it: for my professional development as a coach and for the fun, supportive community they created. Our coaching calls are a great time to share experience and crowdsource ideas for a specific scenario. Between us we have A LOT of experience, and being a JDC coach makes me a better coach."

Rachel’s philosophy is to coach the individual and that means listening and building strong channels of communication. She prioritizes her athletes' goals and also their life commitments so she can create a program that is in balance with their lives. She does this thru lifelong experience as someone who, herself has juggled life as a student-athlete, age group athlete and working lawyer, working lawyer and professional athlete, and ultimately, professional athlete and mother. Rachel is passionate about empowering people to embrace the fact that the balance with training and life isn’t static but ebbs and flows depending on life events and sporting goals. She understands time management and the need to maximise “bang for buck”. In her final year of professional racing, being new Mum to Archie, she lived by the mantra “You can only train as much as you can recover from”.

Following her retirement from professional racing, where she was a 5-time Ironman Champion, and 3x podium finisher at the Ironman World Championship, Rachel can be found coaching with JDC, coaching a run club at her son’s elementary school and being active outside with her family and friends. She's "dabbled" in some ultra trail running and finished 8th at the Leadville 100 Trail race in 2021.

Asked for her proudest coaching moment, Rachel says:

“I coached an athlete to his first Ironman finish after 3 previous attempts. The process of preparing wasn’t easy as he was shoehorning his training into an incredibly demanding work schedule. We communicated well, had frank discussions and I won’t forget power waddling with him in the final miles of the marathon, at 8 months pregnant and seeing him achieve his goal.”

Dede Griesbauer

Dede is 53 years young and is the oldest actively racing professional triathlete on the planet. And she's been coaching nearly as long!

Dede's first coaching client was her nextdoor neighbor, when she lived in Boston, MA back in 2006. "She wanted to race an Ironman and asked me to coach her. I'd only been doing triathlon for 4 years myself and told her I knew nothing about coaching. She ultimately convinced me that in spite of my few years of racing experience, I still knew more than she did. So I accepted the challenge."

Over the course of the next nearly 2 decades, Dede's coaching roster grew, largely by word of mouth. She's coached athletes of all abilities from pure beginners to seasoned elite age group athletes and across all distances and disciplies. She enjoys coaching busy working age groupers because, "I was a busy age grouper myself, when I got my start. I raced for 2 years as an age grouper alongside being a busy career as a Wall Street Vice President. I love making the pieces of the puzzle fit together for each individual athlete so that endurance sport fits into their lives and enhances it. Not dominates it."

Dede takes that Wall Street professionalism to her coaching as well. "I think response time and communication is key to any good working relationship....just don't text me after 7, because that's when I go to bed! But I'll get back to you by 5AM!"

Dede joined the JD Crew coaching staff in 2021 (??) because "I learn so much from Julie and from my fellow coaches. I love the collaboration we share and when I feel I'm stuck helping a client, I lean hard on the 5 other experts I work with to find the right path foward."

Dede's experience includes coaching first time sprint triathletes, all the way up to the most experienced Ironman athletes, as well as ultra distances, where she is the Ultraman World Champion, and World Record holder.

"Mostly I want to share my passion for the sport. Sport has given me so much in life and I want to share that with others to help them achive their goals, be it making it to the finishline of their first 5k, or winning their age group at a World Championship"

Paul ‘Barney’ Matthews

Paul Barny Matthews grew up in a little town called Murwillumbah (bonus points for any non-Aussie who can pronounce that) in Australia before coming to America and now lives in Austin, Texas. Barny did his first triathlon when he was 7, joined the Tweed Valley Triathletes club when he was 11 then did his first professional race when he was 17. As a professional, his race highlights being winning the first ever IRONMAN 70.3 race in the UK in 2005 and finishing 2nd at the Asia/Pacific IRONMAN Championships in 2014 in a time of 8:02:13 and a run of 2:44:07 in front of his family and friends. 

Barny started coaching in 2017, putting all those years of experience to use and rolling them into his own brand and coaching philosophy.  

In 2021, however, he had the opportunity to join the JD Crew. 

“Throughout my racing career I always surrounded myself with the best. I’ve trained with an Olympic champions, and medalists, world champions, and world record holders. I’ve trained under some of the best coaches our sport has seen so when Julie asked me to join her team, I took it as a huge compliment and saw a huge opportunity to keep growing as a coach, once again, surrounded by the best.  The way we all put our heads together to come up with the best solution for our athletes is a great team effort. The amount of experience we have in our coaching ranks is second to none and we use that to great effect to provide the best service and guidance to our athletes."

Outside coaching, Barny loves spending time with his two kids, playing Aussie rules football with the Austin Crows and watching all the sports; especially Liverpool, St George Illawarra Dragons, Sydney Swans, Denver Broncos and Denver Nuggets.
