John's dedication, honesty and constant support has helped me in my journey to become a top cyclist. The most important thing he has shown me is that I need to believe in myself more.

I've been with John for many years now, through my Motocross days and then I carried on training with him when I moved to cycling..He has a great understanding and a lot of patience with each individual athlete, which is really important. He is always trying to find ways to make you better and stronger through his coaching, I have complete confidence in what he gives me to do

Starting to work with Jeroen was the most important step I did in my career so far. I trust and believe in his work 100% and I love to follow and furthermore feel the progress we did already in our first year. I‘m sure he is the one who can help me to become the best version of myself!!

From when I started with Jeroen, the effective allocation of training, energy and rest was clear to me. I’ve taken steps up repeatedly since. His knowledge of the sport that is cycling and human physiology is incomparable and I have no inch of doubt in me when it comes to trusting the process he sets out for me so that I can achieve my targets in this sport and set my mark. He has helped me more than anyone to get closer to where I want to be in performance measures, all while he was dead honest and perfectly realistic about what I should expect from myself. This is how I like to work, this is why I train with Jeroen.
