When you register you can indicate that you want to use this. You can also request this later by logging in to your Njuko environment.


The competition area is located at the sandy beach on the beautiful swimming water of the Haarlemmermeerse Bos. There are catering establishments on and around this site and you can look around the expo.

Bring as many supporters as you can imagine. The event area is also a wonderful place for them, where they can encourage you and enjoy the wonderful summer atmosphere themselves.


About one week before DTS HLMRMEER we will carry out a first measurement of the water temperature. As soon as it is known, we will post it on our Facebook page and on this website. The rules for wearing a wetsuit:

– Temperature below 15 degrees: wetsuit mandatory

– Temperature between 15 and 22 degrees: wetsuit not mandatory, but allowed

– Temperature above 22 degrees: wetsuit prohibited

When you register it is possible to rent a wetsuit for € 40. Already registered but still need a wetsuit? No problem! Until registration closes (on Tuesday 12 May), you can still log in to your Njuko environment and still rent a wetsuit.
