Czech Republic's Jiří Prskavec has claimed the gold medal on home soil in the men's kayak event at the International Canoe Federation (ICF) Canoe Slalom World Cup leg in Prague.
The Olympic bronze medallist put down a time of 90.42sec to take a popular win ahead of Italy's Giovanni de Gennaro, who finished more than four tenths down with a best of 90.87.
Far behind for the bronze medal was Mathieu Biazizzo of France with a best of 92.01 - enough to hold off Britain's Joe Clarke, who finished half-a-second behind in fourth.
The United States' Michael Smolen was fifth, followed by Slovakian Jakub Grigar, Czech Republic's Vit Prindis and Spain's David Llorente.
Slovenia's Peter Kauzer and Czech kayaker Vavrinec Hradilek completed the final field.
Poland recorded a one-two in the women's kayak final, with 22-year-old Klaudia Zwolińska claiming the gold in a time of 100.58.
She was nearly two seconds ahead of her compatriot Natalia Pacierpnik, who made the podium at the ICF World Cup for the first time.
The two-time Olympian showed she was capable of beating some of the best in the field, finishing more than three tenths ahead of the bronze medallist, Australian two-time Olympic medallist Jessica Fox.
Just 0.17 seconds separated Fox from fifth-placed Luuka Jones of New Zealand, and Britain's Kimberley Woods separated the regional rivals.
Spain's Maialen Chourraut was a distance behind in sixth, followed by Germany's Elena Apel, France's Camille Prigent, Czech Republic's Antonie Galuskova and Ricarda Funk of Germany from seventh to 10th.
