Belgium's International Regatta of Bathtubs was held on Sunday.

Starting in 1982, participants vie to create the most impressive bathtub-based craft and compete in the one km regatta down the Meuse River in Dinant on Aug. 15 each year.

This year's event has been downsized due to the COVID-19 pandemic.
