Our Founder

Meet Abraham Spring
Head Coach

Abraham delivers world-class strength and conditioning, making sure athletes are robust, resilient, and peaking through structured periodisation. His focus is on getting bodies strong enough to handle the full load of training, from sprint triathlons to Ironman.

He will lead on:

  • Strength & Conditioning: program design, coached sessions, progressions, testing, and injury-prevention so athletes can handle full training loads and peak on time.

  • Running Mechanics – assessing and correcting technique so athletes run efficiently, stay injury-free, and unlock more speed.

  • Nervous System Reset & Regulation – using meditation, breathwork, and recovery practices to keep athletes composed under pressure and ready to perform.

  • Holistic Coaching – blending strength, endurance, mindset, and recovery into one system that builds not just fitness but resilience.

  • Social Media & Storytelling - capturing athlete journeys and showcasing the process in a way that builds community and inspires others.

Abraham brings more than two decades in sport across football, triathlon, Brazilian Jiu-Jitsu, wrestling, crit racing, and track (400m). He is also the only coach in the UK to have spent over 100 days in silent meditation, experience that gives him a unique approach to mindset and performance.

The result: athletes who are not just trained, but fully prepared physically, mentally, and emotionally.

Head of Nutrition

Meet Tess Ström

Our Head of Nutrition at Unbroken, overseeing the full spectrum of our athletes’ nutritional needs.

As a Nutritionist and Functional Medicine Practitioner, she is passionate about using food as both fuel and medicine helping athletes adapt, recover, and thrive. Her work ranges from hypertrophy-focused nutrition to support strength and muscle development, through to endurance fuelling, recovery strategies, and protocols to keep inflammation under control.

Tess uses blood work and functional testing to uncover the physiological and biochemical imbalances that often limit performance. Whether it’s addressing nutrient deficiencies, hormonal stress, or recovery bottlenecks, she creates tailored nutrition and lifestyle plans that help athletes stay consistent, avoid injury, and peak at the right time.

Her approach is science-based, holistic, and athlete-centred. At Unbroken, Tess ensures every athlete has the nutritional foundation not just to perform on race day, but to sustain long-term health and resilience across their training journey.

Swim Manager

Meet Katherine Pires

Katherine brings more than technical skill to the pool she brings presence. Known for her empathetic, kind coaching style, she understands exactly what triathletes need to build confidence and speed in the water.

Her sessions are never flat. Katherine’s fun, charismatic personality keeps the room engaged, making athletes feel at ease while still pushing them to refine every stroke. She blends sharp technical detail with encouragement, ensuring progress feels natural, not forced.

With years of experience in technique refinement, Katherine specialises in helping triathletes sharpen their front crawl, focus on the details, and translate efficiency into lasting endurance.

Training with her means more than swimming laps. It’s about finding flow, rhythm, and trust in the water. You leave every session sharper, lighter, and ready to carry that energy into the rest of your training.

Content Design

Meet Simon Kaplan

Simon is people-first in everything he does. Warm, thoughtful, and driven to support others, he sees content not as words on a page but as a way of making life clearer, simpler, and easier for the people who use it.

Simon will help the way we communicate making sure every message has a purpose, every word works hard, and every interaction feels human. He’s in charge of guiding our content strategy, setting the standards for clarity and accessibility, and helping teams design experiences that people can trust and enjoy.

For Simon, great content is about connection. His focus is on building systems and stories that serve people, not overwhelm them.
