Not sure where to start?
A free 20-minute call. Not sure which format fits, what your level needs, or whether to start in the pool or open water? We talk it through. No commitment.
If your environment is the bottleneck — not your technique — we’ll talk about that too. That’s where the system lives.
Group clinics for clubs and teams.
Two formats. Small Group (3–8, €50 p.p., 90 min) and Large Group / Teams (8–16, €35 p.p. or €500 flat, 120 min). The club brings the pool and arranges lanes — you tell me the date, level, and focus; I bring the coaching. Three optional add-ons: Video Analysis, Nutrition Q&A, Parent Education.
One clinic won’t change your environment — but it will show you what mine looks like.
Lake training, four ways.
Drop-in sessions (€5) or a 10-session strip card (€90, save €10). Three programs: Learn Freestyle (€150, 8 sessions, beginners), Better Freestyle (€125, 6 sessions, base), Technique Clinics (€70, 3 sessions, triathletes). Zevenhuizerplas · May–October.
A program builds a skill. The system builds the environment that keeps that skill working.
