How nice that you are thinking about joining Tweeslag! Tweeslag is a student beachvolleyball association where you can always find your place, whether you have never set a foot on sand, or even when you are a professional. We train through the whole year (except for when a pandemic prevents is from doing so) and we are not held back by bad weather. Luckily, we do train inside during the winter. We also organize a bunch of other fun things next to training sessions. With monthly tournaments, borrels and activities there is always something to do. After showing off on the beach court, we roll into the 'Brouwerij' via a running dinner for a borrel lasting until the early morning. So, if you want to increase your beachvolleyball skills, would like to find sand in you shower drain for the whole year or just want to meet fun people, come take a look at Tweeslag!
