The race under the slogan "Let us save the Drava from new hydro-power plants!" will be organised by the World Wildlife Fund Adria (WWF Adria), and the local environmentalist organisation ZEUS together with the Matis rafting club, with the start in the northern Croatian town of Donja Dubrava. The beginning of the race is timed for 9 am.
Saturday's race will be accompanied by other events to entertain participants in the regatta.
"The rivers Mura, Drava and Danube constitute a 700 kilometre green belt that networks nearly one million hectares of one of the most important European river basins," ZEUS and Matis club said last year before the start of the ninth edition of the race, recalling that the region is also called the European Amazon.
The organisers also recalled that in the summer of 2017, the WWF multiannual campaign in Croatia called "Our rivers, our treasure" was held on several rivers.
"More than 200 rowers paddled down Sava, Drava, Kupa, Zrmanja, Korana and Mreznica, with support of Slovenian Olympic athlete Rok Rozman, who is also originator of the whole story through its Balkan Rivers Tour. The campaign aims to save Croatian free-flowing rivers from planned hydropower plant constructions and other damaging projects," according to information issued on the WWF Adria website on 14 June 2017.
