Triathlon & Endurance Training

  • The Journey Is Yours.

    The Path forward
    is together.

Every athlete's journey is different. The individualized training I provide reflects that.

Are you thinking about your first triathlon? Dreaming about crossing the finish line of your first Ironman or Marathon? Or are you the athlete frustrated that you have not reached your full potential? I help athletes not only reach and cross their finish lines, I help athletes reach their potentials by not just training their bodies but also break down the mental barriers holding them back. We will create a personalized plan and belief system that fits your goal

Through expert guidance, accountability, and ongoing support, we’ll build the confidence and consistency to help you perform at your best. 

 

Every finish line starts with a decision.

Meet Your Coach

Dena Colie

I’ve experienced the excitement of crossing finish lines, the challenges that come with training, and the lessons learned through every setback and breakthrough along the way. From completing Ironman races to representing Team USA, endurance sports have shaped not only who I am as an athlete, but also the coach I’ve become.

My Coaching Services

Whether you’re preparing for your first race or striving for your next personal best, I’ll create a training plan tailored to your goals, experience, and lifestyle.

The Principles Behind the Plan

My Coaching Philosophy

Success doesn’t happen by accident. It comes from a thoughtful approach built around four key elements:

Goals: Clear direction creates meaningful progress. Every plan begins with understanding what success looks like for you.

Balance: Training should complement your life, not compete with it. Sustainable progress comes from consistency.

Mindset: Confidence is built one workout, one challenge, and one breakthrough at a time.

Guidance: An experienced coach helps remove the guesswork, provides accountability, and keeps you focused on what’s next.

Achieving More, Together

Words From the Athletes

What's Possible With the Right Support

Coach Dena is amazing! She trains the whole athlete from workouts, nutrition, recovery, mindset and everything in between. She helps you achieve your goals. As an athlete herself she is always learning, listening to the latest information and sharing it with her athletes. Not only have I become a faster triathlete but I am more knowledgeable about the sport.

Mandi

Over the past 6 years, Coach Dena has become more than just my triathlon coach, she has become a partner in my Ironman journey. Weekly check-ins and multiple opportunities to train and race together has produced a foundation to build a customized training plan. The check-ins has allowed my feedback to be incorporated into more of a colaberative plan, a plan that is challenging but more importantly prepares me to race with the confidence I can achieve my goals.

Gregg

Dena Colie is an amazing coach! She has coached me through four 70.3 Half Ironman, a Marathon and one Full Ironman. Her coaching from tweaks on the bike, to my running gait or nutrition intake has been invaluable. She is hands on and assesses your workouts daily. It really helped me to become a stronger triathlete as well as love the sport!! She is also a top level age group athlete- she got 2nd at Ironman Des Moines and 3rd at the T100 in Lake Las Vegas this year. ⭐️ 🏆

Laurie

Dena, I want to thank you for the coaching I receive from you. Seriously! Your training style is something but motivational approach helped me greatly. Lucky to have you as my coach!

Darlene

Dena is a coach who will always go above and beyond for athletes.  She understand that each athlete is unique and will always fine tune training plans in order to assure success.  Dena also makes it a priority to continue to learn about new advancements in training and coaching.  This advanced knowledge of endurance training is one of the many assets of having Dena as a coach.  All of my biggest racing accomplishments are attributed to her being my coach.

Scott

Seamless transition from my coach of six years to Dena. Excellent communication skills. Always knew what the goal of the workout was and the why. Responded to questions promptly, incredibly consistent. Thorough and professional… Coaches the whole person, physical and mental. Of the mindfulness exercises included with physical workouts. Passionate about her athletes, our sport. Genuine interest in the well-being of her athletes. Knows when I needed a kick in the pants and when a handout would be better. Achieved a personal race goal this year that I had been pursuing since 2019.

Karen

I have been coached by Dena for two years, each year I had a PRred every race I raced. She is very attentive, direct, and most importantly nimble during my difficult times.
