“For the past two years, Ronald de Haan has been my go-to training partner (well, remotely, that is). His coaching approach is stimulating, challenging, and exactly what I needed to prepare myself for a full triathlon. He always strikes the right tone – whether it’s to pump me up, give me a kick in the pants, or get me to reflect on my performance (yes, even on those missed swim sessions).
What really sets Ronald apart is his passion for data. He meticulously analyzes every session’s stats and effortlessly translates that data into concrete improvements. Every workout became not just a physical challenge, but a smart step toward the ultimate goal. His sharp eye for both performance and numbers helped me bring out the best in myself.
The training is varied and tailored perfectly to my progress as an athlete, but it’s the mental aspect where Ronald truly shines. He didn’t just make me stronger physically; he also helped me build trust in myself, which I needed more than I realized! His commitment is undeniable—whether from a distance or up close, he always knew exactly what was going on in my head.
In short, if you’re looking for a coach who not only makes you better but also helps you discover who you really are as an athlete – with a healthy dose of data love – then Ronald is your guy!”
