Head Coach Jason Shields

Coaching Philosophy:

With over 15 years of coaching experience, I’ve guided athletes through both breakthroughs and setbacks. I believe effective coaching isn’t about pushing harder at all costs — it’s about training smarter, with purpose and balance.

My approach focuses on building a strong foundation so athletes can perform at their best while staying healthy, consistent, and motivated for the long term. There’s no quick fix — just consistent, well-structured training that leads to lasting results.

If Your Dreams Don't Scare you, They are not big enough

Jason Shields

What do you Love about the Sport? 

When I transitioned from football to triathlon, I quickly fell in love with the sport. I thrive on the challenge — the racing, the training, the discipline. Now, as a coach, I get to share that passion and watch it light a fire in others. That’s what drives me every day.

What inspires you?

Since the start, I’ve believed that if your dreams don’t scare you, they’re not big enough. That mindset has shaped my journey — as an athlete and as a coach. I’m inspired by athletes chasing their limits, big goals, and bold ideas. Anything is possible when you trust the process and back yourself.
