Zwemloop Wassenaar

The Wassenaar Swim-Run, known as the i4Housing Zwemloop Wassenaar, is an annual event held on the last Sunday of August. Participants swim in the sea and run through the dunes, with options for both a full and half distance. The event features a unique course that showcases the protected dune area along the Dutch coast.

Since 2022, there is also a standalone trail run option of approximately 10 km. Participants receive a commemorative item, and there is an opportunity to enjoy a barbecue after the event. Registration is open until a few days before the event, with various participation fees. Visit the organization's website for the most recent information.
