Ragnar has a big, enthusiastic swimming section. We offer four practices a week and join five big swimming tournaments a year! The practices are made so swimmers of every level can join, as long as you have some basic swimming skills. Each lane has its own level. In the first one, swimmers learn the basics of every stroke, and in the fastest lane you will find swimmers who have swum their whole lives.

Would you like to come and try out a practice for free? Send an e-mail to our swimming commisioner (zwemmen@ragnar-rotterdam.nl), so that we can agree upon a date on which you can attend a practice!


During the season, Ragnar competes in six student swimming competitions (called NSZKs and NSK). The NSZK competitions are held amongst the 11 universities’ teams in different cities in the Netherlands. The NKS consist of a regular competition and one open water competition accessible to all students in the Netherlands. Every competition starts on Friday with a social drink. On Saturday, we compete in the water. After that, we all have dinner together. We finish the weekend with a big party. Depending on the distance where the competition takes place, we either sleep in Rotterdam or in the hosting city.
