What is that symbol ?

ΔTRI (pronounced "Delta Tri") represents everything we do here. In mathematics, the greek letter delta (uppercase/lowercase Δ/δ) is used to represent the rate of change in a variable (i.e. how quickly something is increasing or decreasing). It is also a TRIangle, representing the 3 sports that make up a triathlon.


This symbol underpins the primary component of my coaching philosophy:

Increase the rate of change

It is our belief that given enough time and resources, most athletes would still improve and learn to set appropriate training for themselves without a coach. The primary role of a coach is to accelerate this process by drawing on experience, the latest research, and adapting to every athlete’s specific needs. At ΔTRI, we use evidence-based methods to improve your rate of improvement.

Enjoy the process

Success will come through consistency. An athlete will only be consistent over a significant period of time if they enjoy the process of training. What is enjoyable is individual to every athlete.

A coaches role is more than just writing training plans. They should add value, by enriching the whole triathlon experience for an athlete. Training should be enjoyable for all involved - if we aren’t having fun, we are missing the point.


Smarter not harder

Training smarter is always better than training harder. Everything we do should be based on evidence. More complex does not mean “better”, it just means more complex. Injuries arise from applying an innapropriate stimulus at the incorrect time for a given athlete. But you should not expect this process to be easy - endurance sport is difficult by nature. That is why we like it.


There is no such thing as perfection

There are many ways to achieve the same physiological outcome - no single training methodology is best for every single athlete. The prescribed training must fit around other elements in each athlete's life. Individualisation is key.

Striving for absolute perfection in training is unrealistic. Plans and goals often need to change, but expecting and preparing for these changes will help get the most out of your performance.


ΔTRI was founded by me -  Matt Wright. I am a triathlon coach, with 4 years experience in squad,1-2-1 and online coaching environments. I am committed to helping ΔTRI athletes get to the highest possible levels in endurance sport.
As an athlete, I have 20 years of experience competing as a swimmer up to national standard. I race triathlon up to domestic elite level in the British Super Series, have won medals at age-group national championships, and qualified for multiple world and european age-group championships (all whilst balancing training with a successful coaching business, a day job in engineering, and a busy social life).
I fully understand how difficult this can be, because I live it on a daily basis.
