Outdoor swimming on the Nieuwe Meer
No walls, no turns, no lane ropes. On Sunday mornings we train in open water with a TSA coach: for fitness, for better technique, or to get ready for a swim event or triathlon.
Season 2027. We share the definitive schedule at the end of March. We plan to start in early May, depending on the weather and the water temperature. Let us know you're interested and you'll hear it first.
Why swim outside with us
Swim further
Open water lets you swim long, unbroken stretches. Group 1 covers 2.5 to 3 km in an hour, group 2 800 m to 1.5 km.
Learn what open water asks
Every week has its own focus: navigating and sighting, drafting behind other swimmers, breathing, and technique sets with different strokes.
Get ready for your event
Training for a swim event or a triathlon? You practise the situations you'll meet on the day, in a group, with a coach watching your stroke.
How it works
- Sunday mornings, 60 minutes, with a TSA coach
- Two groups by distance, so you swim at your own level
- Single sessions and packs of five; prices follow with the schedule
What you need
- Your own wetsuit
- A brightly coloured tow buoy (you can buy one from us)
- You can swim the distance of your group comfortably in the pool
