Brutal Events Swim Start



It was the summer of 2012 and the Olympics had come to London. Already a keen runner I watched in awe as the best athletes from all over the world competed in various sports for the ultimate prize of a gold medal. One event in particular stood out... the triathlon.

I was inspired and that’s where my journey began.


Just a few weeks later, I purchased my first road bike and began swimming at my local pool with the intention of completing my first triathlon the next year… Fast forward to the current time and I have now completed numerous triathlons over various distances including Ironman and Double Extreme Ironman. I have also represented Team GB at World and European Age Group level.


In order to improve my own performances I researched and studied various training methods and programmes already in existence and have gone on to build my own extensive training library. Since beginning my coaching journey with my local club Havering Tri, I have developed both as a coach and as an athlete. In 2018 was appointed Head Run Coach. I am passionate about coaching and strongly believe in a personal and bespoke approach for all of the athletes I coach.

With a young family and full time job, I understand the pressures involved with work, family and social commitments. Therefore, I will develop a time efficient plan which fits around your personal circumstance taking these factors into account. This plan will focus on ‘quality over quantity’ and look to make the most out of every session.

For much of my life, I have been a swimmer and a runner, competing in the water from a young age before becoming more focused on my running as teenager. After many a comment of, "You should try a triathlon...", I eventually bit the bullet and took on the Blenheim Palace triathlon in 2015. Performing far better than I ever imagined - despite completing the cycle on a heavy, relatively old, hybrid bike (hilariously with a set of FFWD wheels loaned to me by my boss...!) I was hooked and so began my triathlon journey. The following year, I qualified as a GB age-group athlete and competed in both the European and International championships.


I have been very fortunate to have been coached by several inspirational and knowledgeable coaches throughout my sporting career. Being a beneficiary of their commitment, dedication and time has not only enabled me to achieve success, acquire skills and a wealth of knowledge but it has also ignited my passion to help others as a coach. In 2018, having coached young athletes at the school I work at for 3 years, I decided to gain further formal qualifications and embarked on obtaining my coach status with the British Triathlon Federation


In my professional role as a teacher, I am adept at working with a wide variety of individuals and utilise this adaptability to my advantage in coaching. I create personalised training plans formulated from a wealth of knowledge of both the sport and importantly, of the athlete and their motivations and targets.

Sport, in particular individual, endurance sport has been my life since the age of 12. I started off in the rough and tumble world of XC mountain bike racing coming in a very respectable dead last in my very first race – on a Raleigh Activator, wearing a pair of jeans.


Over the following years I managed to improve a little at mountain biking, in the end spending 2 years as Northern Irish champion whilst holding a 100% unbeaten record in all races. I also moved into the world of road racing where I held the same win percentage record as well as racing for a large portion of the year in England with future stars of cycling, including future Tour de France winners and prolific bunch sprinters.


As cross training I decided to join my schools XC running team in the winter and found that I was actually a better runner than a cyclist ending up representing Northern Ireland on multiple occasions.


From there the natural conversation led me to triathlon – even though my swimming was laughably bad, which resulted in some ‘interesting’ race performances – in my first Olympic distance race I managed to come out of the water last, by a long way, come off the bike first, by a good margin, then fade badly in the run. But the bug had bitten.


I have been a personal trainer, sports massage therapist and strength and conditioning coach for more than 15 years and am an Ironman U certified coach.


When you work with me, you can expect sessions that will challenge you, support that will help you to push through sessions when you think you aren’t able to but also a learning experience that will empower you to make sensible decisions when it comes to your own management of yourself and your training.
