Husband, Dad, Head Coach & Founder of Tricentraluk

Tony Cullen Ironman Triathlon Coach

Tony has been competing in triathlon events since 2000, and is just as passionate
today as when he started. Although he is still a very competitive athlete in his own
right, he now takes even more pleasure from helping others achieve their goals.

As an active competitor, Tony has tried and tested almost everything there is in his pursuit of excellence. And after years of endless research, he has a catalogue of successful techniques to pass on to his athletes.

But as the sport of triathlon continues to evolve, Tony is constantly looking for ways to improve both his coaching ability and his athletes - making sure he is always making
the very best of their training time.

Tony has always been a highly competitive sportsman, starting off as a young professional footballer. Following spells at Manchester United, Blackburn Rovers & Aston Villa he turned to coaching and was the Head Fitness & Endurance Coach at FC United - one of the biggest amateur football clubs in the country.

After taking up triathlon in 2000, he also started to build a small client base coaching mostly friends. Before long, he decided to take the next step to specialise in long distance triathlon coaching, meaning TricentralUK was born.


With a full time job as an Imports Manager, a passion for fitness, and a wife and
3 daughters - 2 of whom swim with Bolton Metro Performance Swim Squad -
a 4:45am alarm call is the norm in the Cullen household.

But this hectic family lifestyle is what helps Tony understand how important it is to find
a training structure that fits around different lifestyles. So no matter what you want your work-life-training balance to be, you can be sure that we will find a programme that suits you.

Brian Fogarty

SENIOR COACH Tricentraluk

Brian started Triathlon in 2012 after calling time on a football career which involved playing for Burnley FC and semi professional clubs around the northwest. He spent a few years just focusing on running but constant injuries forced Brian into a change.  Being a very strong minded and dedicated person the appeal to do an Ironman was very strong.  He jumped in with no experience and did it. It’s was then that the love for the sport began. Years on Brian’s love and passion has grown to being his life.  He lives and breaths training, racing and is now helping others reach their potential as a coach for TriCentralUK. 

Brian has shown how balancing his full time job working for his Insurance Brokers and still improving his ironman performances are possible, he is now mixing it at the very top of Amateur world Ironman rankings, we are sure it wont be long until he is racing in the professional ranks.  He is now a coach for TriCentralUk after working with Tony since 2016.

“As an athlete i have worked with some the best and worst coaches around, over the years this has given me a huge amount of knowledge and along with my own racing experiences i believe i have alot to offer as a coach and working along side someone of Tony’s pedigree is only going to help me develop further as a Coach”

Karen Driver

COACH Tricentraluk

Karen started her sporting career as a swimmer at a very young, where she was up at 5am before school, sometimes training twice a day and competing at weekends. This set Karen up to become the committed and dedicated athlete she is today.

In 2014 after achieving everything she wanted to in the world of swimming, Karen decided to take on a different challenge and did her first triathlon and surprisingly finished with a podium position, on an old bike with trainers on, totally no idea what she was doing! From that day she was hooked on triathlon, however always wanting to push herself, Ironman was the ultimate goal.

Karen sought the help of Tony Cullen in 2016 and has since grown into a very successful age group athlete. This shows just how far you can come if you are committed to the process and have the right coach, guiding you along the way.

Karen also works full time for Swim England as a Strategic Partnership Manager so as you can see she lives and breathes sport.

“ I believe if you have the right coach who understands your goals, your outside commitments and you as a person, you can achieve anything….
as Ironman says “Anything is Possible”

I feel privileged to be working alongside such well respected and successful coaches as Tony Cullen and Brian Fogarty and know that they will only develop me further as a coach ….Exciting times!
