Based on the theme ‘sports and faith’ we wanted to excite our teenagers. With a professional speaker, who could speak from his experience. We invited Bert Flier. He talked about how he started triathlon and what God and sports mean to him. Based on statements, we discussed being a christian and engaging in professional sports, the tension between living for God and for sports, and about using your talents. It was an inspiring, educational and fun evening where we could ask serious questions and were challenged to make choices.

Last year I was coached by Bert to improve my running. Bert’s insights provided interesting, new information about competitive running and diabetes. I learned a lot about the possibilities of controlling my blood sugar level in training and racing. This provides a great advantage during racing for both diabetics and non-diabetics.

Yesterday really had to kick the habit… The formula for the 3in1Sports training camps is special, where people of all kinds and levels come into their own.

Bert gives you the feeling that everything is possible and nothing is mandatory. The different levels and goals were taken into account as well as personal injuries, aches and other imperfections.

A big thanks for the coaching to half Ironman Stein! Sometimes it was difficult to make the necessary time commitment, but this was truly one of the best things I have achieved in sports.

Sports became a real voyage of discovery for me. The result: I lost 10 kilos, went via the half marathon to the full marathon, then to the half Ironman… and this year on to the Ironman!

Thanks for the inspiring clinic! During the core stability training Bert knew how to make us feel muscles that we had long forgotten.

When I committed to your coaching last year I never thought I could make so much progress. It was an eye-opener in terms of structure, types of sessions and joy in training, but also in terms of lifestyle, nutrition and attitude to life.
