Phazon Triathlon uses IRONMAN and British Triathlon certified coaches to deliver personalised triathlon coaching based in SouthWest London. We believe that anybody regardless of age, size, ability or experience can complete a triathlon with the right approach and training.

Why work with a coach?

IRONMAN Certified Coach - Simon OlneyCoaching is the most cost efficient way to improve your performance. A bespoke coaching plan looks at every aspect of your training and lifestyle to optimise your performance on race day, as well as your general health and wellbeing.





Why choose Phazon?


At Phazon Triathlon we believe that triathlon is more than just a sport, it’s a mindset. We help athletes train as efficiently as possible with focused, specific workouts and generous rest periods to allow your body to recover. Injury prevention and quality of life are at the forefront of what we do, ensuring athletes maintain healthy social and professional lives alongside their training.

We can help develop you whether you are a non-swimmer who hasn’t ridden a bike since their childhood, or an experienced triathlete looking to improve their times or step up a distance. We believe in building a strong personal relationship with our clients to help us understand what you’re looking for from the program, and allow for an open dialogue between both parties.

Do I have to live in London?
Not at all! Our level 1 and 2 programmes are distributed worldwide via TrainingPeaks, where we analyse your sessions and discuss progress to help you improve your performance on race day.

Our 1 to 1 and group coached sessions cover the SouthEast of England and can be arranged further afield under special arrangement.


How Personalised is the training?

Personalisation is the cornerstone of what we do, building every single training plan from scratch based on the results of your initial questionnaire to ensure it’s the right plan for you. We will never provide you with a pre-written training plan, and edit the plan as we go to accommodate for illness, injury or change of circumstances.

What do you require from athletes?
An open mind and a willingness to learn is all we require from prospective clients, however to get the most out of your training, a turbo trainer, GPS watch and a finis tempo trainer are highly recommended.


Sounds great, when can we start?
Simply give head coach Simon a call on 07515666325 or drop him an E-mail on Simon@phazontriathlon.com to arrange a no obligation meeting where we can discuss your training and goals.

I absolutely recommend Simon as a coach. His approach to training, knowledge and attention to detail made him the perfect fit to coach me round my first IRONMAN race. Simon got me to the start line, fit and injury-free with a solid race plan. I also had a smile on my face at the finish line..! I will be working with Simon again for IRONMAN number two and I can recommend his services to anyone that is looking for a coach. – Ben Griffiths, first time IRONMAN Finisher

I hired Simon to help me complete my first IRONMAN 70.3 From the very first moment Simon has been excellent. Advice on swimming which I find the hardest discipline and worked with me at building a plan for me to meet my goal of completing an IRONMAN 70.3 Great workouts that are posted on time with notes and each workout explained so I know what is expected of each time I Swim, Run or Cycle. Simon is also around for any questions or queries that I may have about my training and is also working with me on recommending which 70.3 I should be taking on and also planning when I should be doing some warm up Olympic triathlons. I highly recommend Simon for all levels of athlete and I am looking forward to working with Simon to reach my goals for many years to come. – John Wooley, 70.3 athlete
