OT³ Performance Coaching is a results-driven triathlon coaching service led by professional triathlete Ollie Turner, delivering personalised, evidence-based training for athletes committed to long-term progression.

Ollie has been coaching triathlon for over 7 years, working with 40+ athletes across a wide range of abilities and goals. He holds a BSc Sport & Exercise Science from Cardiff Metropolitan University, providing a strong scientific foundation to his approach to athlete development and performance.

Alongside his academic and coaching experience, Ollie has spent 8 years within the British Triathlon high-performance environment, training and working around some of the sport’s leading coaches, practitioners and athletes. This has provided direct exposure to world-class coaching methodologies, performance environments and applied sports science, which he combines with his own experience competing internationally across middle- and long-distance triathlon.

OT³ applies the overarching principles of sport and exercise science to guide training design and coaching decisions. This encompasses areas including exercise physiology, biomechanics, psychology, strength and conditioning, nutrition, recovery, performance analysis and coaching theory.

These principles provide the framework for understanding how an athlete moves, adapts, performs and responds to training. They are then applied practically and individually, taking into account each athlete’s goals, physiology, training history, lifestyle, strengths, limitations and response to training.

Rather than relying on rigid formulas or generic templates, OT³ uses evidence, performance data and ongoing athlete feedback to continually refine the training process. The objective is not simply to complete more training, but to deliver the right training stimulus, at the right time, for the individual athlete.

Every programme is therefore fully bespoke, designed around the athlete and the demands of real life. Whether the goal is an age-group qualification, a podium, a personal best, or completing a first triathlon, coaching is built around developing performance, consistency and sustainability.

OT³ works with a small, focused group of athletes, allowing for clear communication, detailed data analysis and continuous performance review. Coaching extends beyond swim, bike and run to encompass race strategy, nutrition, strength & conditioning and long-term athletic development.

At its core, OT³ Performance Coaching exists to build durable, resilient athletes—athletes capable of training consistently, racing intelligently and performing at their best when it matters most.
