Coaching terms and privacy policy

Coaching Collaboration Terms

Last updated: January 2026

  1. Coaching is a long-term process. The plan is flexible and adapts to life, not the other way around.
  2. Communication happens primarily by email. It's the fastest and most reliable form of contact.
  3. Mark urgent matters in your email as URGENT. I respond as quickly as possible. Other messages are handled within the scope of your plan and its priority level.
  4. I usually build plans in blocks (typically 4 weeks), but during race periods or with frequent changes, the plan may be more dynamic.
  5. STANDARD means: weekly review of execution and optional adjustments to upcoming weeks of the block.
  6. VIP means: high flexibility and more frequent modifications for an irregular lifestyle (e.g. sales professionals, business owners, people with shifting schedules).
  7. Data and feelings matter equally. I see the numbers, you feel your body – report fatigue, pain, drops in motivation, illness. 10 hours of training too little is better than 100 metres too many.
  8. I build the next plan after the current block ends, to avoid duplicating work. The weekly structure stays consistent – no surprises like "cycling was always on Monday and suddenly it's swimming".
  9. Pausing or ending the coaching relationship is done by email. Disappearing without notice creates chaos and costs on both sides.
  10. Personal data is used solely for the purpose of delivering coaching services (GDPR).
Full terms including organisational details (billing conditions, notice periods, etc.) are sent by email when coaching begins.
