HAVOC ATHLETES
Testimonials
"When I first reached out to Brett, I honestly had no idea what I was doing. I’d come from a gym bro background, could barely swim to save my life and had plans to sign up for an Ironman 70.3.
From day one, Brett backed me. Every session had a purpose and whenever I had questions he was always happy to explain the why behind the training. He never over complicated things or made me feel silly for asking. He just kept me focused on trusting the process and showing up.
Over the 20 weeks, I went from someone who was nervous just getting through a swim session to crossing the finish line of my first Ironman 70.3 back in my hometown. That wasn’t just because of the training plan. It was because Brett knew when to push me, when to pull me back and how to keep me moving forward without burning out.
The biggest thing I’ve taken away from working with Brett isn’t just the fitness. It’s learning the value of patience, consistency, and understanding that you don’t have to nail every session. You just have to keep showing up. Those lessons will stay with me long after race day.
If you’re looking for a coach who genuinely cares, knows his stuff and wants to see you succeed, I couldn’t recommend Brett enough. I’m excited to keep building on what we’ve started."

"I first connected with Brett from Havoc Training in July 2025 through Facebook. After a short phone call about triathlon, I signed up and I've never looked back.
Brett is professional, knowledgeable, and always responds promptly to any questions or queries. Over our 12 months working together, he's taught me the value of training consistently and showing up every day.
The results speak for themselves. At the 2025 Busselton Ironman 70.3, Brett helped me achieve a 23-minute PB and finish 10th in my age group, a huge improvement from my previous 23rd place finish.
I wouldn't hesitate to recommend Brett to anyone in endurance sport."
HUGH DAVIDSON
"I started training with Brett in January of this year with some clear goals in mind and have been able to accomplish these with his expertise and guidance.
Brett clearly lays out the training plan and I have really enjoyed feeling the progression as we work through the various training blocks. My favorite thing about Brett is his emphasis on smart and consistent training.
Brett is also super available and very responsive to any questions I have about the training, gear, nutrition or races. It’s been great having such a positive and engaged coach to help me push myself and smash some PBs!
I can’t recommend Brett enough for anyone new or experienced."
MAX HAZEL-HARRISON
"I’ve had a great experience working with HAVOC and Brett for the last couple of years. The training program is tailored specifically to me, my goals, strengths, and areas for improvement. It’s much more than just swim, bike and run sessions. Brett incorporates strength work and focuses on the key areas that will make the biggest difference to my performance. The feedback and guidance is always relevant to where I’m at and what I need to improve, which has help me continue progressing and staying motivated. He’s also incredibly responsive whenever I have questions and provides timely feedback on key training sessions.
What really sets him apart though, is how invested he is in his athletes. He genuinely cares about helping you achieve your goals and celebrates the journey with you along the way. On more than one occasion, he’s unexpectedly shown up at events to offer extra support, encouragement and coaching when I least expected it. Having him there at the finish line cheering me on has meant a lot and speaks volumes about the type of coach and person he is.
If you’re looking for a knowledgeable, supportive and genuinely caring coach, I couldn’t recommend him highly enough."
CLINT MAYBERRY
"Before I met Brett, I had completed three half Ironman distance races entirely on my own, with no structured training or professional guidance. While I was proud of my accomplishments, I always felt there was another level I could reach—something missing in my preparation and performance.
That all changed when I started training under Brett’s guidance. From the moment I began following his detailed daily plans, the game completely transformed. His approach wasn’t just about putting in the miles; it was about training smarter, not just harder. Even from the other side of the world, Brett’s coaching felt personal and relentless—pushing me beyond my perceived limits while ensuring I trained with purpose and efficiency.
In just three months, I went from being a self-trained triathlete to being fully prepared for my first full-distance IRONMAN. But Brett’s influence extended far beyond physical training. He educated me on the importance of nutrition, not just during training but throughout race day. He helped me understand how to fuel my body properly, pace myself strategically, and stay mentally sharp throughout the gruelling 140.6-mile challenge.
Looking back, I can confidently say that Brett didn’t just make me a better athlete—he reshaped my entire approach to endurance racing. His guidance turned what once seemed like an insurmountable goal into an achievable reality, and for that, I’m incredibly grateful"
