Meet Arthur

Hi triathletes,
My name is Arthur de Niet and I have been working with Dora in the Trifharder team from the start approx. 4 years ago, first as an athlete and  since 2023 I am also an IRONMAN certified coach myself and joined the coaching team.

Next to Triathlon coaching I also work on motivation and have done several courses on motivational coaching. Doing an Ironman is not just doing the physical part, you also have to be mentally prepared for it. That's why I started to offer mental coaching for athletes; just to get that last bit out of you that you can't get by just training more and harder.  I am certified both in Neuro Linguistic Programming (NLP) and in Hypnosis (see below). 

Neuro Linguistic Programming - Certification at the American Union of NLP ( Cert. #: 5729
Hypnotherapy - Certification at the American Alliance of Hypnotists ( Cert #: 3978.

To help athletes  (and everybody else interested to make more out of  life) I have written the motivational book "FastForward to your ultimate success" but for the athletes that prefer to watch video's over reading books I have also created the online course "Fast Forward Program" at  Both are easy to process, but strong hands on help to get you focused on what's important for you in life and in sport.   To get you started go to the Get Started! section of this website and download the ebook "Goal setting 101" for free.  

For 2023 I have a few shorter races in the agenda then full triathlon and I am looking forward to start working together will you all!
