Your supporters are welcome here to cheer you on. Also outside at the finish there is plenty of opportunity for your supporters to cheer you on.


About one week before DTS OUDERKERK we will take an initial measurement of the water temperature.

As soon as this is known, we will post it on our Facebook page and on this website. Rules for wearing a wetsuit:

– Temperature below 15 degrees: wetsuit required

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