MEDICAL DEVICE ENGINEER >>> PRO ATHLETE & Triathlon Coach

Hey, I'm

Coach Shangrila Rendon.

/// Let's Get Real for a Moment 🌟

You're not here by accident. You're here because you're driven, you've accomplished a lot, and you want to achieve more—in triathlons, in endurance, and in life.

You're no stranger to ambition. But there's more to this than just medals and podium finishes. There's a journey, a personal transformation and sometimes, it's a comeback story.

/// From Medical Engineering to Triathlon Engineering—Here's Why That Matters 📊

Before diving into the triathlon world, I spent 15 solid years as a medical device engineer.

Why does that matter to you? Because my love for problem-solving, numbers, and data didn't stay in the lab—it’s integral to how I approach coaching. I left a secure career because I found something that married my analytical skills with a deeply personal mission: helping others excel, in every sense.

/// A Bit About Me and Why It Matters to You

I've navigated through some heavy stuff—battles with depression, PTSD, and years of struggles that I wouldn't wish on anyone. But here's the transformative part: I discovered triathlons. They weren't just races; they were my lifeline.

Now, as a 2x Guinness World Record Holder, my mission is to guide people like you through their own transformative experiences.

/// Why I Founded Feisty Fox Coaching 🦊

Our coaching isn't about turning you into a machine that only knows how to race. It's about making you the best version of yourself, on and off the course.

It's about smart, focused training that respects your time and your body. You're here to be incredible, but you also want a life outside the track, right?

We're about developing the complete athlete—and person—in you. I use the same rigor and analytical thinking from my engineering days to design a path where your biggest dream goals become possible.

/// The 5 Pillar Method—It’s Comprehensive 🌱

We take a holistic approach. Think Training, Nutrition, Body Maintenance, Mental Fitness, and Race Strategy.

We've got a fantastic team, from a registered dietician to a physical therapist and sports performance psychologist, who work in harmony to help you excel. We're solving the entire equation for you.

/// What You Can Expect

Our athletes aren't just surviving races—they're setting personal bests and actually enjoying the process.

They're taking on top-tier races and coming out strong, without burning out, sacrificing their well-being, or their relationships.

/// Our deeper mission is about empowerment.

Our mission isn't just about turning out great athletes; it's about empowering people to overcome and transform. Because, life gains a new level of beauty when you face challenges, emerge stronger and be the best you can be.
