About Me
Your IRONMAN certified coach on the road to the finish line
Training Champions Since 2021
I'm Katherine Gomez Aya, IRONMAN Certified Coach and triathlon specialist — 16 years as both athlete and coach, having lived every stage of the journey: the early mornings, long training sessions, mental battles, and the satisfaction of crossing the finish line.
Since 2021, I coach athletes of all levels, from first-timers to competitors targeting IRONMAN 70.3 and 140.6. Every plan is fully personalized — blending sports science, structured methodology, and a champion's mindset across swimming, cycling, and running to maximize performance and minimize injury risk.
My mission: guide you step by step toward your goals — your first Sprint Triathlon, a 70.3, or the podium at a full IRONMAN 140.6.
Because every finish line starts with a decision to begin.

Testimonials
Athletes who crossed the finish line with my training
Made it over the line! Both times :) No chance I would have been able to achieve these goals without Coach Katherine. She was brutally honest with feedback and kept me on track when my motivation was low. The weekly check-ins really helped me understand my progress and I could feel my body tolerating the loads better every week. Highly recommend for anything from a 5km all the way to a full Ironman.
I have been training with Coach Katherine for over 2 years. I started from zero — no base fitness at all — and now I'm running 5km with great times and a well-conditioned body. I'm very happy with my coach, extremely professional.
Coach Katherine, thank you for the exceptional coaching throughout these seasons. Your strategic approach to my training for Ironman 70.3 Barcelona, San Andrés Colombia, the East to West Marathon, and the T100 Doha was world-class. I particularly appreciated how you balanced the intensity for such diverse races while keeping me injury-free and focused. Your expertise has been instrumental in my performance.
I have been training with Katherine for a while now, and I must say her trainings are very efficient and easy to follow. The weekly trainings are different depending on the race you want to do. I have trained with Katherine for 2 years now and I can fully recommend her.
I have been under Katherine's guidance for almost three years and the results speak for themselves. She has been with me from my first marathon at the Qatar East to West all the way to international challenges like Ironman 70.3 Lima and the T100 Doha. I deeply admire her technical approach and the clarity with which she plans each goal. The fact that she is my sister only adds a level of trust that makes the work even stronger.
Preparing for the Bogotá Marathon with Katherine was an experience built on complete trust. Midway through the process I got injured outside of training, and her ability to adapt the entire plan was what allowed me to keep going. She was on top of not just the mileage, but also my nutrition and how to manage the aches that came up along the way. Having that level of support gives you the peace of mind you need to reach your goal.
