Kinderclinic Open Water Alkmaar: entering the water well prepared

Published on: 2 June 2026

On Sunday 28 June, Open Water Alkmaar will take place at the Hoornsevaart. A tough and sporty event for anyone who loves swimming. Children can take part too. Swimming in open water is just a little different from swimming in a pool. That is why a special Kids' Open Water Clinic is being organised on Thursday 25 June.

During the clinic, children practice swimming in open water. There are no lines on the bottom there, the water is darker and sometimes colder than in the swimming pool. There can also be water weeds and little fish. That makes swimming outdoors fun and adventurous, but sometimes also a bit daunting. By practising beforehand, children will start with more confidence during Open Water Alkmaar.

What are we going to do?

During the clinic children learn what it is like to swim in open water. They practise sighting, continuing to swim calmly and dealing with situations that are different from those in the swimming pool. It is also discussed what you can do if you need help, for example with cramp or if you choke.

Where and when?

The clinic takes place on Thursday 25 June from 18:30 to 19:30. It might run a bit over. Swimming is taking place in the Geestmerambacht, in the pool near restaurant El Chiringuito on the north side of the lake. There may also be a short swim in the main lake. Participants will gather at the picnic table near the small playground.

Who for?

The clinic is intended for children taking part in Open Water Alkmaar and for those who are going to swim with them.

What are you bringing?

Bring swimwear, swimming goggles, a swimming cap, towel, flip-flops and a water bottle. Depending on the weather, a wetsuit or swim/surf thermal top is useful. Also remember warm, comfortable clothing for afterwards, possibly a bathrobe and something to eat for after swimming.

Guidance

The clinic is given by Esther de Vries. She has had her own swimming school, is a lifeguard and has been giving swimming lessons to children for years. In addition, she is an experienced open water swimmer, from out-and-back swims in the Geestmerambacht to crossing the IJsselmeer.
