Personal Coaching

Every personal coaching trajectory starts with an intake interview and lactate test. We get to know one another, set goals and determine your training structure, tailored to your situation, level and objectives. The lactate test provides insight into your energy balance, your physiological strengths and points of development and determines your training zones.

From exercise test to training plan

3in1Sports uses exercise tests to assess your metabolic profile. Based on lactate readings we assess your physiological strengths and weaknesses and set your training zones. By repeating these tests, we can track and trace your progress and adjust if needed.
Trainer Bert Flier

Talking with your coach

Your coach has personal contact (phone or whatsapp) with you at designated times  to evaluate your progress and to set up your training sessions. Between calls you can email or app any questions you may have. We track your progress via TrainingPeaks, DIY tests and lactate tests.


3in1Sports has teamed up with a sports doctor, physiotherapist, and specialists for cycling, running and swimming technique analysis.

For whom is personal coaching?

3in1Sports coaches athletes of all levels – from beginner to world class. A Personal Coaching trajectory is for every one who wishes to be coached one-to-one:

  • Tri- and duathletes
  • Runners

3in1Sports does not work with contracts. After the intake you receive per email the invoice for the intake and the first 12 weeks – the minimum period for a Personal Coaching trajectory. After that period you will receive your invoice every 4 weeks, which you can pay be automatic payment of via a payment request You can adjust the coaching frequency, pause or stop at any time after the first 12 weeks, without any conditions.

Extra exercise test

Natuurlijk kan je tijdens een Personal Coachingstraject extra inspanningstesten laten afnemen. Een inspanningstest kan je ook helpen na een periode van ziekte of onderbreking van je training, zodat je weer verantwoord en onderbouwd de draad van de trainingen kunt oppakken.

Extra inspanningstest: €149
