Working with Stefan as my Ironman coach has been an absolute privilege.

Stefan is an amazing character and an incredibly dedicated coach who truly wants the best for his athletes.

His training plans are very well structured and tailored, giving clear direction while still adapting to individual needs. He checks in regularly and is always available with valuable advice—not only on training itself, but also on recovery, race nutrition, strength work, and swimming technique.

What really stands out is how invested he is in his athletes’ progress. His attention to detail, consistency, and genuine passion for coaching make a huge difference. I’m extremely grateful to have had the opportunity to work with him and would highly recommend him to anyone looking to take their endurance performance to the next level.
