Basic Open Water Course 2026

A total of 6 one-hour training sessions, each with a different theme.

**Beginner open water swimmers learn the ins and outs of outdoor swimming, such as navigation, water safety, and equipment handling. Advanced swimmers can learn to swim more efficiently, get more out of their strokes, and improve their fitness. The course is ideal for recreational outdoor swimmers, or participants in a city swim or triathlon. We also use video to explore your potential improvements. If you have any questions, please contact us at michiel@topswim.nl.**

HBSF series

Have you already taken the course, or are you an advanced open water swimmer? Then you can also participate in the HBFS (Harder, Better, Faster, Stronger) series.

In these training sessions, we delve deeper into open water techniques, endurance, and race tactics. Expect less theory and more swimming! This series runs from 8:00 PM to 9:00 PM, following the Basic Course hours on Wednesdays and Thursdays, at the same location.

Change training days?

That's no problem! You can change days/locations twice during the course period.

For questions please reach out! DM +31626034210 or meet me at the tracks or pool.

I hope to see you in the open water!

Best, Michiel
