Tony Cullen – Head Coach & Founder, TRICENTRALUK
Tony Cullen is one of the UK’s most sought after and respected long and middle-distance triathlon coaches. With an illustrious background in professional sports, Tony's journey began as a footballer, playing for top clubs like Manchester United, Blackburn Rovers, and Aston Villa. After his playing career, Tony transitioned to coaching, becoming the Head Fitness & Endurance Coach at FC United—one of the country’s largest amateur football clubs. It was here that Tony first discovered his passion for endurance sports, setting the foundation for his future in triathlon.
In 2000, Tony embarked on his triathlon journey, quickly building a small but loyal coaching client base. It wasn’t long before Tony realized that coaching was his true calling, leading him to establish TRICENTRALUK. Under his leadership, TRICENTRALUK has grown into one of the most respected coaching programs in the country, known for producing exceptional Ironman athletes and fostering an inclusive, supportive triathlon community.
As a coach, Tony’s credentials are second to none. He has personally earned over 10 qualifications for the prestigious Ironman World Championships in Kona, and his athletes consistently achieve elite-level success. One of his most notable coaching achievements is Ben Akin, whom Tony guided from a relatively inexperienced triathlete to a sub-8-hour professional Ironman and coach in his own right. Tony’s track record includes countless personal bests, Ironman podiums, and World Championship qualifications.
Tony’s approach to coaching is both data-driven and highly personalized. Having competed at the highest levels of the sport and with a sub-9-hour Ironman to his own name, Tony has tested nearly every method available in his pursuit of excellence. His carefully developed coaching philosophy centers around finding the right balance between training, work, family, and social life—helping athletes achieve their full potential without sacrificing the things that matter most.
As triathlon continues to evolve, so too does Tony’s approach to coaching. He remains at the forefront of the sport, always seeking new ways to improve both his own abilities and those of his athletes. Whether you’re a beginner looking to complete your first triathlon or an experienced competitor aiming for Kona qualification, Tony’s expertise and tailored training programs will help you reach your goals.
Beyond coaching, Tony has built a strong team of dedicated coaches at TRICENTRALUK, each sharing his commitment to athlete success. Together, they coach athletes of all levels, with a focus on creating customized training plans that maximize performance. The club’s active community prides itself on being inclusive and welcoming, ensuring that every athlete, regardless of experience, feels supported and inspired.
